PushUnlock — Work Out to Unlock, No Awkward Poses

Do pushups to unlock apps without lying down in public or setting up your phone first

Problem

Users who want a "do pushups to unlock your phone" app find current options annoying: you must prop up the phone so the camera sees you, and doing pushups at a gas station is embarrassing—so people quit.

Solution

Replace camera-based pose detection with phone-only motion detection using non-posture exercises (shake, grip, rapid squats) that you complete while holding the phone naturally, no stand or camera framing needed.

Users

Everyday users and students who want to cut phone use and like fitness, but don't want to perform publicly.

MVP

Accelerometer-based recognition of 1–3 handheld exercise motions (e.g., rapid squat counting); require a target count before unlocking; no camera; integrates with iOS Screen Time / Shortcuts; simple streak stats.

Revenue

Free basic version plus subscription for more exercises, stats, and app allowlists ($3–5/mo), or one-time purchase.

Why now

Phone addiction and digital wellbeing remain hot topics, and existing camera-based competitors have poor UX—sensor-based unlock is a clear wedge for an indie dev.
