The longer the list, the less you move. Today Only Three does the opposite of every other to-do app. ◆ Three. That's all you get. There is nowhere to write a fourth. That is the whole idea. Choosing the three things that actually matter today is the hardest work you'll do — and the most effective. ◆ Resets daily. Nothing carries over. When the date changes, today's sheet is replaced with a blank one. Unfinished tasks never pile up in red the next morning. If it still matters, you write it again by hand. Every day is a fresh commitment. ◆ Finishing feels good A big checkmark and haptic feedback. Clear all three and confetti celebrates the moment. ◆ Your streak takes shape Two separate streaks: days you wrote, and days you cleared 3/3. Haven't written today? Your streak holds until the date changes. ◆ For night owls Decide where your day ends yourself — "anything before 3 AM counts as yesterday" (0–5 AM configurable). ABOUT ADS One small banner sits at the bottom of the Today screen and the review screen. It is placed where it won't get in the way while you're writing. REMOVE ADS (one-time ¥100 / $0.99, no auto-renewal) Want the banner gone? One purchase removes it permanently. Every feature is free and unlimited (three slots, daily reset, streaks, monthly calendar, plain-text export). Nothing is unlocked by purchasing. Only the ads disappear. Stop working hard at task management. Today, just three.

Verdict

The call

The clearest difference is in-app purchases: BrainBox at none against 今日3つだけ's 1. BrainBox also leads on ads (none vs shown) and device support (4 vs 1). On price there is nothing between them.
