What's New in Fifteen
3.1
August 3, 2026
Two new ways to lock, and neither one waits for your willpower. SCHEDULE — Recurring blocks that fire on their own. Pick the days, the hours, even every-other-week. Overnight windows included. AI — On-device only. Fifteen learns when you habitually reach for the apps you are trying to quit, then warns you before that moment arrives and offers you the lock. It never locks you without your say-so, and your usage data never leaves your phone. ALSO IN THIS RELEASE - A running lock no longer takes over the whole app. The countdown stays, but you can step out to manage Schedule and AI, then step back in. - Larger, easier controls throughout, especially the time pickers. - Every mode now comes with three free sessions before Pro. - Many fixes to blocking accuracy, trial counting and purchase restoring.
