No subscriptions, ads, accounts or in-app purchases. SEE YOUR N-LEVEL PROGRESS Follow the levels you practice across weeks, months and years. View daily, weekly or monthly averages and ranges, and see when you first completed each level and how much practice led up to that milestone. A practiced level is not a claim of mastery. GO DEEPER THAN A SCORE Explore position and sound accuracy separately, hits, misses, false alarms, sensitivity and correct-response timing. Compare sessions with date, level and cadence filters. Inspect a spatial performance map and a trial-by-trial ledger. BUILD A DAILY RHYTHM Use optional energy and focus check-ins, separate check-in and training streaks, an activity calendar and local practice reminders. Miss a day without losing your history. MAKE IT YOUR PRACTICE Start with a guided introduction. Choose your N level and pace, check your sound, and pick from three voice treatments with optional haptics. KEEP YOUR RECORD Your training history stays on your device unless you choose to export it. Back up and import JSON records, export raw CSV for analysis, or share a block result without your private check-in ratings and notes. Device backups follow your Apple settings.
