About this app

📷 A sit-up coach that counts for you with your camera

SitUp Coach is a fitness app that recognizes your sit-up form through your smartphone camera and automatically counts your reps. On-device AI analyzes your form in real time and counts only correct movements. Just stand your phone on the floor and start exercising right away.

■ Key features

✅ Automatic camera counting
It analyzes the angle between your torso and thighs in real time to automatically count your sit-ups. Half-finished movements and overly fast reps that rely on momentum are treated as invalid, so only properly performed reps are counted.

🦴 Real-time posture feedback
The screen shows a skeleton overlay and a posture badge (Good posture / Adjust posture / Not detected). It automatically pauses when no person is visible and resumes when you are detected again.

🔊 Voice count (TTS)
It reads your count aloud so you can focus on your workout without looking at the screen. You can adjust the voice volume in the settings.

🎯 Goal and record management
Check today's achievement at a glance with a daily goal and a progress ring. It provides session summaries (valid / invalid reps, average tempo), history, and graphs by period.

⏱️ Set and rest presets
It supports presets such as 3 sets x 20 reps and 5 sets x 10 reps, plus a custom mode where you set the sets, reps, and rest yourself. It announces set completion and rest time by voice.

🔔 Workout reminders
Receive a workout reminder notification at a time you set each day to build a consistent habit.

🔒 Privacy first
All processing happens on your device. Camera footage is never stored or transmitted; only coordinates are used and then immediately discarded.

⚙️ Convenience features
Front / rear camera switching, light / dark theme, and use it right away without signing in.
