3.1.0
August 12, 2026
New in 3.1: the app now teaches you! Tap Teach Me for a step-by-step lesson on opening your first combination lock, with an arrow right on the dial showing which way to turn. Made a wrong turn? The lock now explains what happened instead of silently resetting. Plus My Locker: save your real locker's combination, practice it, and look it up if you ever forget it (saved only on your device). Locks with numbers up to 49 are now fully supported, and the whole app got a cleaner look.
