Some thoughts don't need a folder, a title, or a five-step workflow. They just need to be written down before they disappear. Sidenote is a quiet capture app for the in-between moments - the reminder you think of on a walk, the sentence that arrives in the shower, the idea you don't want to lose before you reach your desk. Open the app, start typing, tap Done. Your thought drops into a simple stream, timestamped and waiting whenever you scroll back. No accounts. No sync. No noise. Everything stays on your iPhone. CAPTURE WITHOUT FRICTION Sidenote opens ready to write. A single prompt, a clean canvas, and nothing else competing for your attention. When you're done, your thought settles into your stream with a subtle, satisfying motion - then the screen is clear again for whatever comes next. Drafts are saved automatically, so if you're interrupted mid-thought, nothing is lost. YOUR THOUGHT STREAM Scroll down to revisit earlier sidenotes, grouped by day with timestamps. Search when you need to find something specific. Edit a note, share it, or remove it with a long press. Export your entire stream as plain text whenever you want a copy outside the app. Removed sidenotes stay on your device for 30 days, so you can restore them if you change your mind. GO LIVE Pin any sidenote to your Lock Screen and Dynamic Island with Go Live. Keep a reminder, a phrase, or an idea in sight for up to eight hours - without opening the app again. Choose a default or clear appearance to match how you want it to look on your Lock Screen. HOME SCREEN WIDGET Add a Sidenote widget to see your latest thought at a glance. Tap it to jump straight back into your stream. MAKE IT YOURS • Light, Dark, or System appearance • Font choices: System, New York, Georgia, or Mono • Adjustable text size across the app, widget, and Live Activity • Thoughtful haptics and animations (respects Reduce Motion) Sidenote is designed to feel calm, fast, and personal - like jotting something in the margin of your day. PRIVATE BY DESIGN Sidenote keeps your thoughts on this iPhone. There is no account to create, no server to sync to, and no data leaving your device. Your sidenotes belong to you. Built for people who think in fragments, capture in bursts, and want a place that stays out of the way until they need it. Start typing.

Verdict
The clearest difference is update cadence: Sidenote at every 8 days against Aqua Temp's monthly. Aqua Temp's advantage is iOS requirement (15.0 vs 18.0). On price, ads, in-app purchases and device support there is nothing between them.
