Didmark is the dead-simple way to remember when you last did the small, recurring things — take your meds, change the HVAC filter, water the plants, give the dog his pill, clean the litter box. No planning. No projects. No streak guilt. Just one tap to log that you did it, and Didmark remembers the rest. ONE-TAP LOGGING Tap Done next to any task to timestamp it instantly — or log one you did earlier today or this week. That's the whole loop. KNOW AT A GLANCE Every task shows how long it's been — "3 days ago," "just now" — so you can see what needs you without thinking. A CADENCE THAT LEARNS YOU Didmark quietly learns your real rhythm from your own logs and flags what's coming due or overdue — no rigid schedules to maintain. A REMINDER WHEN IT'S DUE Turn on the bell for a task and Didmark sends a notification on the morning it expects the task to be due. HISTORY WHEN YOU WANT IT Every completion, grouped by day, with any note you added — and fix a mistaken log in a tap. NO ACCOUNT NEEDED Start right away. Create a free account only if you want your tasks backed up and synced across your devices. FREE FOREVER FOR THE CORE Track up to 3 tasks free, forever — one-tap logging, the cadence lane, due predictions, reminders and your full history included.
