Some tasks just feel too much. And when new ones come up, we often tackle them first — even if they’re not that important. "Shiatomawa" takes a different approach. It’s a task manager designed around a simple rule: do things in the order you added them. [Tasks always go to the end] Every new task is added to the bottom of the list. [Focus on the one at the top] All you need to do is handle the task at the very front — one by one. [Only two actions: “Done” or “Later”] Decide whether to do it now or postpone it. There’s no sorting, no reordering — ever. On devices that support Apple Intelligence, your AI assistant will cheer you on. Even when you’re stuck on a tough task, it might just give you the push you need.

Verdict
The clearest difference is update cadence: Shiatomawa at every 2 days against NanaTimer's weekly. NanaTimer's advantage is iOS requirement (17.0 vs 26.0). On price, ads, in-app purchases and device support there is nothing between them.
