TRMR AI runs an on-device motion engine that steadies the screen in four places, PDFs, Maps, web browsing, and webmail, so reading and navigating feels calmer if your hands shake. PDF Stabilizer is free forever; Maps, Web, and Email unlock for a 7-day trial then cost $0.99/month as TRMR Premium. It processes motion data on-device, needs no account, and says plainly it's an assistive display tool, not a medical device that diagnoses or treats anything.

What holds up

- +No account required and no third-party trackers, motion and location data stay on-device
- +States plainly it's not a medical device and doesn't diagnose or treat tremors, no overclaiming

- −Maps, Web, and Email Stabilizers cost $0.99/month after a 7-day trial, only PDF stays free
