You already know what you should be doing. Time Tiger is the habit coach that's incredibly annoying about making sure you do it — and 100% effective. COMMIT TO A HABIT Gym, running, reading, drinking water, waking up without snoozing — pick the thing you keep putting off. Once you commit, Time Tiger won't let you quietly skip it. THE ALARM RINGS UNTIL YOU START A real alarm that breaks through silent mode and Focus — and only stops with photo proof. Say you'll hit the gym at 7:00, and your phone won't go quiet until it sees you there. PROOF, NOT PROMISES Check off a habit with a tap, or hold yourself to evidence: a photo or screenshot, checked and then immediately discarded — never stored. PUT MONEY ON THE LINE Add a commitment stake and you'll only lose it if you quit. Nothing makes you show up like real money on the line. Questions or stuck?
