Write down what you have to do, so you stop forgetting it. That is all this app does. Tasmo is a to-do app you can write in the moment you think of something, and search later when you cannot remember the words. There is no account and no sign-in. Your tasks and memos stay on your device. ■ Fast to write Tap + at the bottom right and start typing. Every task has a memo field, so you can keep the detail you will need to remember next to the task itself. ■ Due dates and reminders Give a task a date and a time, and a notification arrives at that time. You can also be told early — 5 minutes before, an hour before, or the day before. You no longer have to remember today's list yourself. ■ Home Screen and Lock Screen widgets Keep your list on your Home Screen, or on your Lock Screen. You can tick tasks off in the widget itself, without opening the app. Each widget can show what you want: everything unfinished, or only tasks with a due date. ■ Folders and tags Work, chores, shopping, study. Make folders and keep them apart. There is no limit on how many. Tags cut across folders, so you can also group things as "urgent" or "this week". ■ Search when you only half remember Search task names, memos and tag names — across every folder at once, not just the one you are in. Matches are highlighted, so you can see why a task came up. ■ Subtasks Hang the individual steps under a bigger task. Nesting stops at one level, so a list can never get so deep that you lose track of it. ■ Recurring tasks Repeat on an interval ("every 3 days"), on days of the week ("every Tuesday", "weekdays only"), or on dates of the month ("the 1st", "end of month"). When the day comes around, the task is added for you. ■ Nothing is lost when you delete it Deleted tasks go to the trash. If you delete one by mistake, you can restore it. ■ Make it yours Switch between light and dark, and change the theme color. Sort by hand, by due date, by color, or by tag. Give individual tasks a color, so you can pick them out at a glance. ■ English and Japanese The app follows your device language, and you can also choose one in Settings. ■ iPhone and iPad Both are supported. ――― Your tasks and memos are stored on your device and are not sent to a server. Writing, searching and reminders all keep working in airplane mode. Note: ads and anonymous usage statistics do use the network. Tasmo is for you if - You are tired of switching between a notes app and a to-do app - You have tried a powerful task manager and never got the hang of it - You rebuild the same shopping or packing list every time - You want to start using something now, without signing up Free to use, supported by ads.

You know GTD. You just couldn't keep it going. This is for you. What stops it is the effort. Sort everything into lists, name it, review every week... and you are back to a plain to-do list. Imaya is the GTD loop itself, with the heavy parts made light. ■ Capturing is not deciding Whatever comes to mind goes into the Inbox with no name and no place. The field returns to you, so you can throw the next one in straight after. You can capture without opening the app: - A Home Screen widget (with the count waiting to be clarified) - A button on the Lock Screen or in Control Center - The share sheet in other apps - Siri and Shortcuts, out loud, while walking ■ Clarify one at a time Imaya asks one question at a time. What is this? What kind of action? Is it yours to do? Once there is an answer, the questions stop. The name is built from what you wrote, so you are never handed a blank field. When no name comes, ask the AI for a draft (Premium). It moves only when you ask, and marks drafts as drafts. ■ See only what you can do now Next Actions has two views. - Available now — only what passes where you are, the tools and time you have, and the energy you have left - All — the whole list, with what you cannot start yet faded and the reason beside it At @Home, nothing from @Work appears. Away from your desk, switch @Computer off. Place and time are judged by your phone; the rest is yours to say. ■ It tells you when you can act Set a defer date, a place and contexts as conditions. When all are met, the action appears in Available now and can alert you: when the date arrives, when you reach the place (pick a one-off place on the map), or when the action ahead of it is done. Arriving can sound an alarm until you stop it, even with the app closed (iOS 26 and later). ■ A stalled project does not stay stalled Finish an action and Imaya asks: what is the next move on this project? When nothing comes to mind, pick from the action ideas you jotted down. ■ Delegate it, then stop remembering it Send a link. If they use Imaya, the task lands in their Inbox, and accepted, declined and done come back to your Waiting For list on their own — so you never have to ask "how's that going?" Anything waiting more than seven days gets a flag on Home. ■ Above your projects "I want to live more healthily" becomes a project that never ends, and gets forgotten in Someday/Maybe. Four horizons sit above: Areas of Focus, Goals, Vision, Purpose and Principles. Nothing here holds actions — they are for reading back over. ■ Once a week, trust the system again The Weekly Review looks past the lists. It names the actions untouched for 30 days, shows what you finished this week, then asks: what would you change about how you work? ■ You can always turn back Everything you make can be deleted. Anything that cannot be undone asks first, and shows exactly what happens, in numbers. What you delete waits in the Trash. Export any time, free: readable (Markdown) or a copy with nothing missing (JSON). - - - - - - - - - - - - - - - ■ Pricing The app is free and shows ads. Imaya Premium (auto-renewing) gives you: - AI drafts for names (projects, routines, actions) - No ads - Apple Calendar events in Next Actions and the Calendar - The same data on your Mac - Filter by how long things take ("I have ten minutes") - Filter by energy (on a tired day, only the light ones) Premium (monthly) $2.99 / month Premium (yearly) $29.99 / year First month free (new subscribers) The subscription renews at the end of the period unless you cancel at least 24 hours before it ends, and your Apple Account is charged.
