MotionBloom: Tremor & Rehab

MotionBloom

About this app

Tremor feedback and neurorehab practice in one app.

MotionBloom combines live camera-based tremor estimates with guided movement practice for neurorehabilitation. See feedback during games, Focus activities and Video Gate sessions using your Android phone or tablet.

Observe tremor-related movement
An on-screen score estimates tremor-related movement from camera hand tracking. Calibration supplies a personal reference for in-app feedback. Camera scores are estimates, not clinically validated tremor severity measurements. Intentional movement, camera motion and tracking errors can affect the results.

Practice specific movements
The guided activities focus on hand and finger control:
• Reach the Targets: move your index finger to each target.
• Follow the Path: follow a moving guide at a comfortable pace.
• Touch Each Finger: bring your thumb toward the highlighted finger, then relax.
• Move and Place: pinch a virtual object, move it to the target, then release.

Make practice interactive
Use hand movements to control games, with MotionBloom's animated characters alongside the activity. Focus provides guided practice, and Video Gate connects practice to video playback. The app shows movement feedback during the activity rather than treating a completed exercise as proof of recovery.

Keep your account ready
Stay signed in between sessions. If a compatible calibration is saved to your account, MotionBloom can load it instead of asking you to start over. New calibrations sync to your account when connected.

Camera-based, without a watch
This Android release uses on-device computer vision. It does not require or connect to a smartwatch or external motion sensor. Place your device on a stable surface with good lighting and keep your hand in view. Tracking depends on camera performance, lighting and hand visibility.

Understand your data
Live camera frames and hand landmarks are processed on your device. This Android release does not record, save or upload camera video or hand landmarks. Supabase provides sign-in, account management and saved calibration. Activity summaries cover the current app session, not a permanent clinical or exercise history. You can permanently delete your account in the app.

MotionBloom is a practice and self-observation tool. It does not prescribe a rehabilitation program or establish improvement in tremor. It is not a medical device and does not diagnose, treat, cure or prevent a medical condition. It does not replace professional medical advice. Consult a qualified healthcare professional for medical advice, diagnosis, treatment or an appropriate rehabilitation plan.
