Topmost is the simplest possible to-do list. Everything goes on a single stack β€” and you only ever see the one thing on top. Add something new and it becomes the top. Resolve the top and the next thing rises. That's the whole app: one thing at a time, and you can't hide from it. Most to-do apps let you hoard. A 40-item list isn't a plan β€” it's a guilt museum. Topmost makes hoarding impossible by design. No backlog to scroll, no priorities to fiddle with, no "done" pile to admire. Just the thing in front of you, and the relief of an empty stack. THE REWARD IS THE EMPTY SCREEN Clear the last thing and you've earned it β€” a calm, quiet moment that's the heart of the app. Nothing on top. That's the whole point. DESIGNED TO DISAPPEAR β€’ Pure, typography-forward design that follows light and dark β€’ A crisp pop when you resolve something β€” and a warmer one for the last β€’ Undo a pop whenever you need to β€’ Push and resolve from widgets, the Lock Screen, Control Center, Siri, the Share sheet, your Apple Watch, and the Mac menu bar β€’ Syncs across all your devices with iCloud TOPMOST PLUS (optional) β€’ Contexts β€” separate stacks for Work, Home, anything; only one active at a time, so switching stays deliberate β€’ Themes and your own reward colour for the empty screen β€’ Look back β€” a quiet, read-only record of what you've cleared One purchase covers all your Apple devices, forever. Family Sharing included. PRIVATE BY DESIGN No account. No tracking. No analytics. Your stack lives in your private iCloud and nowhere else. Data Not Collected β€” and we mean it. One thing at a time.

Verdict

The call

The clearest difference is in-app purchases: ONE at none against Topmost's 2. Topmost's advantage is update cadence (every 2 days vs every 2 weeks) and device support (5 vs 1). On price, ads and iOS requirement there is nothing between them.
