Scroll - Outliner for Notes, Lists & To-Dos Scroll is a modern outliner that turns scattered thoughts into a clear, structured record of everything on your mind. Notes, checklists, to-dos, plans, and ideas - all in one app, organized exactly the way you think. Most notes apps force you to choose: a quick list here, a long-form note there, a to-do app somewhere else. Scroll brings them together. Nest your notes as deep as an idea needs to go, collapse what you're not working on, and keep a precise, detailed record of your thinking without ever leaving the app. WHY YOU'LL LOVE SCROLL - Infinite outlining - Break any idea down into sub-points, then sub-points of those. Add as much detail as you want and keep it all neatly organized. - Everything in one place - Replace your notes, lists, and to-do apps with a single dynamic workspace that adapts to whatever you're capturing. - Instant search - Jump straight to the exact note you're looking for and start writing in seconds. No scrolling, no folders to dig through. - Track your progress - Mark items complete or cross them off to see what's done and what's left at a glance. - Built for focus - A clean, dynamic design that gets out of your way so you can think clearly and write freely.

Verdict

The call

The clearest difference is review sentiment: Backlog Studio at 100% against Outliner's 77%. Backlog Studio also leads on rating (5.0 vs 4.7) and update cadence (every 2 weeks vs every 2 months). Outliner's advantage is ratings volume (66 vs 1) and device support (4 vs 2). On price, ads, in-app purchases and monetization model there is nothing between them.
