Time every solve.
Understand the slow moments.
Use the local-first Browser Timer for daily practice, sessions, stats, learning, WCA comparison, and supported physical timers. In the iOS or Android app, record a solve and add optional AI coaching tied to sampled moments from the video.
Browser Timer works without an account · Mobile app on the App Store and Google Play
Two focused tools
Practice in the browser. Review recordings on mobile.
The website and mobile analyzer have different jobs, so you can use either one without confusing local calculations with AI estimates.
Browser Timer
A local-first practice workspace with a precision timer, sessions, stats, visual scrambles, algorithm learning, WCA comparison, and supported Bluetooth or StackMat-style timer input. Start without an account; sign in if you want sessions and solves synced through Supabase.
Mobile AI Analyzer
Record a solve in the iOS or Android app. Timing and pause windows are calculated on your device. If you request AI coaching, the app sends up to 12 compressed still images plus timing, pause, and cube-type data through Supabase to Anthropic for visual estimates.
No MP4 or audio is sent for AI coaching. Visual explanations and phase splits are estimates, not move-by-move reconstruction.
Built for deliberate practice
Know which results are calculated and which are estimated
Local-first practice tools in the browser, plus optional evidence-linked visual coaching on iOS and Android.
Browser precision timer
Use keyboard or touch timing, WCA-style 15-second inspection, +2 and DNF penalties, adjustable hold-to-start, and two- or three-decimal display.
Local-first sessions
Practice data starts in your browser with sessions, visual scrambles, and solve history. Account sync is optional, and the local copy remains available offline.
Evidence-linked AI coaching
The mobile app anchors visual suggestions to sampled still images around detected pauses. Low-confidence pause causes are withheld instead of presented as facts.
Traceable progress
Review ao5 and ao12 trends, personal bests, and per-session summaries built from the solves you actually recorded.
Public WCA records
Link a WCA ID to compare public competition records with unofficial practice results. The two sources stay visibly separate.
Learning and hardware
Study algorithm cases in the Learn area, or connect supported Bluetooth and StackMat-style timers where your browser supports them.

Practice vs. Official
Link your WCA ID and see exactly how close your practice bests are to your competition results — side by side. Your practice times stay yours, and official WCA data is always clearly separated from unofficial practice.
