Stroll

Some of your clearest thinking happens on a walk — and then it's gone by the time you're home. Stroll is a calm place to keep it. Leave your phone behind, take an unplugged walk (a sunrise one is lovely), and when you're back, write down the thoughts that surfaced. That's the whole app. No feeds, no streaks that punish you, no noise. WALK FIRST, PHONE SECOND The best walks are unplugged, so Stroll is built to work even when your phone never came along. Just enter how long you were out when you get home. Prefer to time it? Bring your phone on airplane mode — the timer keeps perfect time even with the screen locked and no signal. ONE NUMBER THAT ONLY GROWS Stroll adds up every walk into a single, quiet total: the time you've spent walking and thinking. It never resets and never guilts you. It just grows. A GENTLE PLACE TO REFLECT • A simple, notebook-style space for what came to mind • A calm prompt to get you started • Your past reflections, gathered by day • A quiet "look back" months later, so you can see how your thinking has changed PRIVATE BY DESIGN No account. No login. No ads. No analytics. Your reflections live on your device — they're never sent to a server, and no one (including me) can read them. Optional iCloud Backup keeps a private copy in your own iCloud so your words survive a new phone. FREE, AND IT'LL STAY FREE Stroll is free with nothing locked away. If it's helped you, you can leave a one-time tip to support an independent maker — but there's no pressure, and tipping never unlocks anything. Take a walk. Let your mind wander. Keep what it brings back.

Verdict
The clearest difference is iOS requirement: CBT at 12.0 against Stroll's 15.1. On price, ads, in-app purchases and device support there is nothing between them.
