Building an app for your audience
Workout App MVP: The Features You Need at Launch (and What to Cut)
Short answer: A workout app MVP needs onboarding that places users into a program, a "today" screen, a workout player with logging and rest timers, basic progress tracking, a subscription paywall with a free trial, reminders, and the account features Apple requires. Leave community, nutrition, wearables, live classes and AI coaching for version 2. Every feature you cut gets you to launch, and to real user data, sooner.
What should the core loop of a workout app be?
Before listing features, define the loop. Every feature should serve it:
Open the app → know exactly what to do today → do it → feel progress → come back tomorrow.
If a feature doesn't make one of those five steps better, it doesn't belong in the MVP.
The MVP feature list
1. Onboarding quiz → program placement
Ask 4–7 questions: goal, experience level, available equipment, days per week, session length, and perhaps injuries or focus areas. Then show the user their plan right away.
This does double duty. It personalises the experience, and it builds investment right before the paywall, which lifts conversion. (Paywall conversion)
2. "Today" screen
The home screen should answer one question: what do I do today? A big button to start today's workout, the week at a glance, and a streak or progress indicator. Don't open on a library of 200 videos.
3. Workout player
This is where users spend their time, so it has to be excellent:
- Exercise demo (short looping video or GIF)
- Sets, reps, weight and RPE inputs with one-tap logging
- Rest timer that keeps running when the phone locks
- Swap exercise (for when equipment is busy or missing)
- Works with poor gym Wi-Fi: cache the next workout's media ahead of time
4. Progress tracking
Keep it simple at launch: workouts completed, a streak, personal records, and weight or volume history per exercise. Visible progress is what keeps people subscribed.
5. Subscription paywall
Monthly and annual plans, a free trial, and clear pricing and terms (Apple requires them). Use RevenueCat or a similar tool so you can change offers without shipping an app update. Restore purchases is mandatory.
6. Notifications and reminders
Let users pick their training days and a reminder time. Add a nudge if they miss a planned session. Keep the volume low, because annoying notifications get switched off for good.
7. Account essentials
Sign in with Apple (required on iOS if you offer other social logins), email login, password reset, and in-app account deletion, which Apple requires for apps with accounts.
8. Analytics and crash reporting
Not a user-facing feature, but non-negotiable. You need to see onboarding drop-off, trial starts, trial conversions and week-1 retention from day one.
What should I save for version 2?
| Feature | Why it waits |
|---|---|
| Community feed / comments / DMs | Needs moderation, reporting and blocking tools (Apple requires these for user-generated content), plus real-time infrastructure. Use Discord, Skool or Instagram for now |
| Nutrition and macro tracking | Basically a second app. Food databases, barcode scanning and recipes are a big build |
| Wearables (Apple Watch, Garmin, Whoop) | Valuable, but most users don't need it to get results |
| Apple Health / Health Connect sync | Nice to have, and a good early v2 feature |
| Live classes | Scheduling, streaming and chat add a lot of scope and cost |
| AI coaching / chat | Can be great, but get the basic program working first |
| Challenges and leaderboards | A strong retention feature, best added once you have enough users to fill a leaderboard |
| Web dashboard | Most users train from their phone |
Which features are worth their cost at launch?
A few features punch above their weight and can earn a place in an MVP:
- Offline mode for the current program: gyms have bad signal, and a workout that won't load is an instant uninstall.
- Home-screen widget showing today's workout or streak: cheap to build on iOS and a steady source of re-engagement. I've built widgets for Dry Quest and they keep the app in front of people every day.
- A "creator message" slot: a short video or note from you on the home screen that you can update remotely. It reminds users this is your app, not a generic tracker.
How does a smaller MVP make more money?
Three reasons:
- You launch while your audience is excited. A launch that slips four months loses momentum.
- You learn what people actually do. Analytics after launch beat any amount of planning before it.
- You keep budget for iteration. The best-performing version of your app is version 1.5 or 2.0, built using real data. Plan budget for it.
Sample MVP scope for a 10-week build
- Weeks 1–2: Spec, designs, content structure, data model
- Weeks 3–4: Auth, onboarding quiz, program engine
- Weeks 5–6: Workout player, logging, offline caching
- Week 7: Progress, streaks, notifications
- Week 8: Paywall, subscriptions, analytics events
- Weeks 9–10: Beta testing, fixes, store assets, submission

FAQ
What's the minimum a fitness app needs to get approved by Apple?
Real functionality beyond a website or a video list, working in-app purchases with restore, clear subscription terms, privacy policy, account deletion if there are accounts, and a demo login for the reviewer. Details in App Store rejection reasons.
Should my MVP include a community?
Usually not. Point users to an existing community (Discord, Skool, a private Instagram group) and build in-app community once you have enough active users to make it feel alive.
Do I need video for every exercise?
You need a clear demo for every exercise, but it can be a short loop rather than a full video. Short loops are cheaper to produce and host, and easier to follow mid-set.
Should I add AI features to my workout app?
AI can personalise programs or make logging easier. My caffeine tracker, Drip, uses AI photo logging, for example. But it should improve the core loop, not replace it. Add it once the basics are solid.
