support@ludyem.devWhat's the difference between the four apps?
Push-Ups, Sit-Ups, Pull-Ups, and Squats are four separate apps that each focus on a single movement, so your home screen stays about the one goal you're chasing. They share the same trainer, plan engine, and watch app — pick the exercise you want to build, or install several.
How does the training plan work?
When you set up the app you enter your current max and a goal (for example, 100 push-ups). The app builds a multi-week ladder of sets and rest periods that ramps you from where you are to your goal at the pace you choose — Relaxed, Standard, or Aggressive. The bigger the gap, the longer the plan. You can change your goal or recalibrate any time from the Plans tab.
How does camera rep detection work? Is it private?
Push-Ups and Sit-Ups can count your reps using the front camera. It runs entirely on-device with Apple's Vision framework — video frames are analysed live and immediately discarded. Nothing is recorded, saved, or uploaded. The camera is only active while you're on the counting screen with detection switched on. You can always just tap to count instead.
Why can't the app write to Apple Health?
The app needs your permission to save workouts. Go to iOS Settings → Health → Data Access & Devices → [the app] and enable the categories you want it to write. You can also grant permission again from the app's own settings.
Does it work on Apple Watch?
Yes. Each app includes a standalone Apple Watch trainer — count reps with taps or the Digital Crown, guided through your plan's sets and rest right on your wrist. Your watch sessions sync back to your iPhone automatically.
How do I cancel my Pro subscription?
Subscriptions are managed by Apple. Go to iOS Settings → [your name] → Subscriptions, select the app, and tap Cancel Subscription. You'll keep Pro access until the end of the current billing period. For refunds, use reportaproblem.apple.com.
How do I restore my purchase on a new iPhone?
Sign in with the same Apple ID you used to buy Pro, open the app, and go to Settings → Restore Purchases. Your subscription will be restored automatically.
The rep counter miscounted. What can I do?
Camera detection works best with good lighting and your whole body in frame. If a count looks off, you can adjust the number manually before saving, or switch to tap-to-count for full control. Detection improves with a stable phone position — prop it up so the camera can see your full range of motion.
Do I need an account?
No. There's no account and no sign-up. Everything is stored on your device, and optionally synced across your own devices through your private iCloud. See our Privacy Policy for details.
