Hukko's alarm does not stop until you do the task. Not a reminder. An alarm โ full-screen, through silent mode โ tied to your to-do. The only way to silence it is to actually do something. - Alarms that don't quit โ repeat until the task is done. Like a clock alarm, but bound to your to-do list. - Active dismissal โ it won't stop until you open the app and respond. Silence it with the action you set for each task: tap Done, slide to complete, type the task name, or check the routine's step. You choose how easy or hard โ but you can't make it stop by ignoring it. - 2-minute start โ "just start for 2 minutes." One nudge to get past the wall of beginning. - Snooze budget โ limited snoozes, then a guilt-free "skip today." Not endless dismissing. A real limit. - Routine chaining โ finish one step and the next alarm arms itself automatically. - Pre-alarms, urgency labels, widgets, and a live countdown. Built for the real ADHD problem: not knowing what to do, but starting it. Gentle notifications get ignored. Hukko doesn't let that happen.
