The Purpose of Extend

Extend your fitness tracking and planning. Log your exercise journey. Use alongside Apple Health. Or don't, it's up to you. No subscriptions, no ads, no unneccesary bloat. Personal records, volume trends, streaks, muscle distribution, and more. Important stats and charts you want to focus on, are readily available where you want them.

What You Can Track

Weights, kettlebells, dumbbells, cardio, bodyweight — any exercise you do. Build routines, log sessions, and watch your progress and personal records build over time. Track water intake. Track the distance your shoes take you.

Customization

Make it yours. Rearrange the navigation bars and build a custom Dashboard with the stats and shortcuts you care about. Choose a light or dark theme and then customize the colors even further. Customize what you see and how you access it.

Getting Started Fast

1. Build a workout routine in the Workout module. Standard sets, complexes, supersets, circuits, intervals (Interval, Tabata, EMOM, AMRAP), rest timers, and audible (voice-called) exercises. Lots to choose from. 2. Want to do a single exercise quickly? Tap ▶ Start Exercise on any exercise in the Exercises module. 3. Unsure what exercises to do? Explore the Generate module to keep your body guessing. 4. Do a workout! a. Start and control from your watch (iphone/ipad can be close by or not). b. Start and control from your iphone/ipad (will mirror on your watch). 5. Save what you've completed and review your progress in the Log and in all related module reports. 6. Optionally, set up a Training Plan to schedule workouts and activities across your week.

Settings

Theme, units, navigation, dashboard, iCloud, HealthKit, Water, and data import/export.

▶

Navigation Bar(s)

Add, remove, and reorder modules across the top and bottom navigation bars. Each bar is configured independently. • Color — set a background color, optional gradient, gradient direction, and text color. • Customize — opens the full nav bar editor to add, remove, and reorder module icons.

Dashboard

Configure the appearance and contents of your Dashboard. • Color — set a background color and optional gradient for the Dashboard. • Customize — opens the tile editor to add, remove, resize, and reorder tiles. Tile types: • Module Shortcut — opens a module. • Stat Card — shows a live stat. • Shortcut — launches a specific workout or exercise. • Blank — fill in space with an animated emoticon. Stat cards available: • Today's Plan • Top Activities • Favorite Day • Workout Frequency • Muscle Group Distribution (7 days) • Volume (Weekly) • Distance (Weekly) • Duration (Weekly) • Personal Record - Weight • Personal Record - Duration • Personal Record - Distance • 1RM Leaderboard • Top Durations • Top Distances • Water Intake (14 Days) • Gear Life Each tile supports optional: custom title, icon, size, accent color and placement, and background tint.

System Preferences

• Theme — Light or Dark. • Image Set — chooses the built-in anatomy images used in workout and muscle views — Option 1, Option 2, or None. • Weight Unit — lbs or kg. Affects all weight display and entry throughout the app — logs, stat cards, personal records. • Distance Unit — mi or km. Affects distance display in stats and complications. • Keep Screen On During Sessions — prevents the screen from locking during active workouts. Uses more battery.

iCloud Sync

Your data syncs automatically to your iCloud account so it's available on every device signed in with the same Apple ID — and survives a reinstall. • Account — shows your current iCloud status. Sync requires you to be signed in to iCloud on the device. • Last Sync — when the most recent push/pull completed. • Sync Now — pulls the latest workouts, logs, exercises, water, and settings from iCloud. Use this if a reinstall didn't restore your data, or after a long offline period. • Sync Appearance Settings — when on, nav bar and dashboard colors also sync across your devices. Turn off if you want different looks per device. What syncs: workout logs, routines, exercises, muscles, equipment, training plans, water logs, journal entries, gear, and (optionally) appearance settings.

Apple Health

• Export Workouts to Health — sends completed workout sessions to the Health app as HKWorkouts (with heart-rate and calories when available). • Use Apple Watch for Workouts — when on, starting a workout on the phone runs a live session on your Watch for accurate heart-rate and calorie tracking. Falls back to an iPhone estimate when the Watch isn't reachable. • Mirror Log — diagnostic log showing the iPhone↔Watch handshake for mirrored workout sessions. • Import Activities — opens a chooser to pick which HealthKit activity types pull into your Log (running, cycling, hiking, swimming, etc.). • Body Weight — optional. Used to tighten calorie estimates for exported workouts. Leave blank to use the default ~70 kg baseline. • Last Synced — relative time since the most recent HealthKit sync. • Sync Now — manually triggers an import (from Health) and an export (to Health) of pending logs.

Water

• Daily Goal — your target intake for the day, in your chosen unit. • Unit — oz or mL. Used everywhere water is shown. • Export to Apple Health — when on, every logged entry is also written to the Health app as a water intake sample. • Import from Apple Health — when on, water samples logged elsewhere (other apps, Siri, Watch) are pulled into Extend. • Last Synced — relative time since the most recent Apple Health water sync. • Sync Now — manually triggers an import from Apple Health (only shown when Import is enabled).

Data

• Export Workouts — exports selected workout routines as a JSON file. Useful as a backup or for transferring to another device. Exports routine definitions only, not logged session history. • Import Workouts — imports workout routines from a previously exported JSON file. Missing exercises, muscles, or equipment are created automatically. • Export Plans — exports selected training plans as a JSON file, including all referenced workouts, exercises, muscles, and equipment. • Import Plans — imports training plans from a previously exported plan JSON file. All dependencies are resolved by name — created if missing, matched if found. • Export Log Data — exports your full session history as a CSV file. • Reset App Settings - Restores customizations to defaults - navbar layout and colors, dashboard tiles and colors, theme, units, sceren-on toggle, game progress, and log view state. Also re-adds the default workouts (suffixed with "(Default)" if you already have one with the same name). Keeps all your data: logs, workouts, exercises, muscles, equipment, gear, plans, journal, water history, favorites, filter presets, and Apple Health / iCloud settings. • Erase All Data (including iCloud) — Clears all data and customizations - logs, workouts, exercises, muscles, equipment, training plans, and settings. This also clears your iCloud copy and will sync the empty state to your other devices. Apple Health import is disabled and a cutoff is set so historical HK workouts don't resurrect if you re-enable Import later. Cannot be undone.

Header Buttons

• 📁➕ — create a new folder to group workouts (see Folders below). • ➕ — create a new workout routine.

Row Buttons

Each workout row shows: • ☆ / ★ — toggle favorite (pins to the Favorites grid at the top). • 🕐 — session history for this workout. • 📊 — stats (volume, frequency) for this workout. • ✏️ — edit the routine. • ▶ Start Workout — launches the session. Swipe the row for more: • Leading swipe — Edit, Clone, Move to Folder. • Trailing swipe — Delete.

Favorites Grid

Favorited workouts appear as 3-piece tiles at the top: • Top — tap to launch the workout. • Bottom-left 📊 — opens stats. • Bottom-right 🕐 — opens history.

Folders

Tap 📁➕ to create a folder. Group related workouts together — Push/Pull/Legs, Warmups, Kids, whatever. • ▾ / ▸ — collapse or expand a folder. • ⋯ on the folder header — Edit, Move Up, Move Down, or Delete. • Edit — rename the folder and pick a color. The color tints the folder's 📁 icon and shows as a thin left accent on every workout row inside. • Swipe a workout to move it to a different folder. • Deleting a folder does not delete the workouts inside — they move back to Uncategorized.

Creating a Workout

Tap ➕ and name it. Add exercises from your library with ➕, or tap 🔗➕ to add a group (Circuit, Interval, or Complex) and then fill it with exercises. Each workout also has: • Notes — optional description. • Warmup / Cooldown — countdown seconds (0 = skip). • Warmup/Cooldown warnings — spoken 3-2-1 at end of warmup and "Starting cool down" when the cooldown begins. • HealthKit Activity Type — how the session is categorized when exported.

Groups (Complex, Superset, Circuit)

Group exercises together. Each group has a color and a type: • Complex — exercises performed back to back with no rest, usually the same weight/implement throughout. Configure rounds. • Superset — two exercises performed back to back, typically opposing muscle groups. • Circuit — three or more exercises cycled through in sequence. Tap the group label to change type or rounds.

Interval Types

Add an Interval block via 🔗➕. Four modes, each with its own parameters: • Interval — classic work/rest. Set work seconds, rest seconds, and rounds. • Tabata — same fields as Interval; defaults follow the 20/10 × 8 pattern. • EMOM (Every Minute On the Minute) — set the interval length (usually 60s) and number of rounds. New round starts on the clock. • AMRAP (As Many Rounds As Possible) — set a total time cap. You cycle through the exercises inside until the clock hits zero. During a session the interval drives the timer; you log reps/weight per exercise as you go.

Rest Timer

Add a Rest item between exercises. Set a label (e.g. "Rest"), duration in seconds, and whether the last few seconds are spoken aloud. Runs as a full-screen countdown with a ring during the session.

Set Options — Repeat Set List and Fill (×N)

Open an exercise's sets editor to configure sets. Two shortcuts speed this up: • Repeat Set List — an integer multiplier (1–100). Instead of listing the same 5 sets 3 times, list 5 and set Repeat to 3. During the session all 15 slots are walked in order. • Fill (×N) — appears inside a Complex when the exercise has fewer sets than the complex has rounds. One tap fills the list up to N using the last set's target and weight as a template.

Logging a Session

Tap the ▶ Start Workout button (or the row itself) to begin. Enter sets (weight, reps, duration) and tap Save/Next Set. Skip forward or back with the chevrons. Previous session values are shown as reference. Tap the exercise's muscle diagram to enlarge the image(s). Complete Workout when done and the session is saved to the Log.

Personal Records, 1RM and Volume

The app tracks PRs, estimated one-rep maxes, and Volume automatically as you log sets. View them on the Dashboard (stat cards) or per-exercise in the Exercises module.

👟

Gear

Track wearable / consumable gear like shoes and bikes with ownership dates, mileage, and retirement thresholds.

▶

What Gear Is (and Isn't)

Gear is for items with an ownership window and cumulative wear — shoes, bike tires, straps, watches. Unlike Equipment, Gear is not attached to individual workout logs at log time. Instead, each gear item resolves usage on the fly by matching a log's date to its ownership window and the log's exercises to its linked activities. Why the split: a new pair of running shoes should automatically count every run from the day you got them, without you tagging every past log — and old runs should keep their prior gear (or none). Doing that with the Equipment model would require rewriting historical logs. Gear resolves at read time, so nothing is mutated.

Header Buttons

• ➕ — add a new gear item.

Row Buttons

Each gear row shows buttons: • ⭐ — favorite / unfavorite. • 🕐 — history of qualifying logs for this gear. • 📊 — stats (lifetime + selected time range). • ✏️ — edit name, brand, icon, activities, dates, threshold.

Favorites Grid

Favorited gear appears as 3-piece tiles at the top: • Top — tap to open stats. • Bottom-left 📊 — stats. • Bottom-right 🕐 — history.

Adding & Editing Gear

Tap ➕. Fill in: • Name (e.g. Nike Pegasus 40). • Brand (optional). • Icon — pick an SF Symbol. • Linked Activities — the exercises this gear applies to (e.g. Running for a pair of shoes). Only logs of these exercises inside the ownership window count toward this gear's stats. • First used — the day you started using this gear. • Retired — toggle on and pick a date when you stop using it, so a replacement pair's stats don't overlap. • Retirement Threshold (optional) — target distance (e.g. 500 mi). The stats screen surfaces a progress bar and warns as lifetime distance approaches the threshold.

Stats

Opens a stats sheet with: • Lifetime — total sessions, cumulative distance, and start date. Always full history, not affected by the time-range picker. • Retirement Threshold — progress bar toward the target distance (only shown if set). Turns orange at 90%, red at 100%. • Time Range Picker — 7D / 1M / 3M / 6M / 1Y / All. Filters the range summary below (sessions, distance, duration). • Linked Activities — the exercises this gear resolves against.

History

Lists every log inside the selected time range whose date falls within the gear's ownership window AND that includes at least one linked activity. Each row shows the date, workout name, and the matching exercises with their distance when available.

Retiring & Replacing

When you get a new pair, edit the old pair, toggle Retired on, and pick the last-used date. Then add the new pair with its own start date — the two won't overlap. Retired gear stays visible in the list (marked "Retired") so its lifetime stats remain accessible.

Gear vs Equipment

• Equipment = static gym items (barbell, rower, dumbbell). Attached to a workout log explicitly at log time. Filters and history use the tagged IDs. • Gear = items you own with a lifespan (shoes, bike tires, wearables). Resolved dynamically from ownership dates + linked activities. Never mutates prior logs when you add or replace an item. If you're tempted to give an Equipment item a start date, it's probably Gear.

💧

Extras

Fun extras built into the app.

▶

Weekly Activity - bubbles

A playful full-screen view of everything you've logged this week. Each of the 7 days is an open-top cup along the bottom of the screen; each workout is a bubble that lands in its day's cup. • Bubble size = calories burned. Bubble color = the workout's primary muscle group. • Tilt your phone to slosh the bubbles around, or tap the screen to send ripples through them. • Use the chevrons at the top to step back or forward a week and revisit past activity. • Score points as you play — your best is saved, and every 100 points a bonus window opens for extra flourish.

Stick Figure Animator

Build frame-by-frame stick figure animations, export as GIFs, and attach them to exercises as how-to references. • Frame Editor — drag joints to pose the figure. Use X/Y controls to position it on the canvas. Adjust scale, limb thickness, and body proportions with the sliders below. • Saving Frames — tap "Save Frame", give it a name. Open the frame list to load, copy, rename, or delete frames. • Animation Studio — tap "Open Studio" to arrange frames into a sequence, set speed, preview, and export as a GIF. • Adding Objects — tap "Add Object" to place emojis, images, or colored boxes on the canvas. Each object can be moved, scaled, and rotated independently.

Empty Tiles on dashboard

Add an empty tile to the dashboard and choose an emoticon to go with it. Wind it up counter-clockwise and let it go to spin forward. For your OCD, it keeps track of how many times you've done it.

Extend has no subscriptions, no ads, and no paywalls. If it's earned a spot on your home screen, a tip keeps development moving — always optional.

Privacy

Privacy as a first principle — short version below, full policy linked.

Extend collects nothing. No accounts. No analytics. No tracking SDKs. No ads. No third-party services.

What lives where:

  • On your device — all workout logs, routines, exercises, plans, water, journal, and preferences.
  • Your iCloud (optional) — if iCloud sync is on, data syncs to your private iCloud database across your own devices. Apple's terms govern that storage. We can't see it.
  • Apple HealthKit (optional) — opt-in import / export of workouts and water. Stays on your device.
  • Apple Watch — data flows between iPhone and Watch over WatchConnectivity. No external server is involved.
  • Exports — JSON / CSV files go wherever you choose to save them.
