If you have ADHD or time blindness, you know the feeling. You had plenty of time. Then somehow you're late again, apologizing, watching someone's face fall. It's not that you don't care — your brain just doesn't track time the way clocks do. Ontime is the external clock your brain is missing. Tell it when you need to be out the door and what your routine looks like. It does the backward math and tells you the exact minute to start — no guessing, no "one more minute." HOW IT WORKS • Backward planning: enter your deadline; Ontime stacks your routine steps and finds your true start time • Start-now alarm: one loud, unmissable alert at the exact minute to begin — not a vague reminder • Step-by-step mode: while you get ready, see what to do now and whether you're ahead or behind • Built-in buffer: pads for the transitions your brain skips MADE FOR ADHD BRAINS • Live Activity: the countdown lives on your Lock Screen, always in sight • Apple Watch: glanceable time pressure without picking up your phone • Widgets: "start in 23 min" right on your Home Screen • Insights: see which routines run over and which weekdays need more buffer • No streaks, no guilt. Just out the door on time. ONTIME PRO Ontime requires an Ontime Pro subscription — monthly or annual, auto-renewing. The annual plan starts with a free trial: nothing is charged until it ends, and you can cancel anytime in Settings. Prices are shown in the app before you subscribe.
