About

Log

Features
Read full description

Log is a thought log for people who turn ideas into reality. Capture an idea in one line. Not a record, but a log for evolution. You wrote it down, then lost track of it. Ideas pile up, but you can't tell what moved forward and what stalled. Log keeps your thinking not as scattered dots, but as a history of change. CAPTURE IN ONE LINE Save a thought before it fades, with the fewest taps. Organize later. Type #tags in the title and they are added automatically. CONNECT YOUR THINKING Link related logs and keep a thought history (v1 β†’ v2 β†’ v3), so you always know where an idea came from and where it went. DIG DEEPER WITH AI Chat with Claude, ChatGPT or Gemini about one log or a bundle of logs. Save a good reply back as a new log with one long-press. AI ideas suggests three next steps: dig deeper, branch out, or move to the next stage. SIX LAYERS OF THINKING Idea β†’ Output β†’ Build β†’ Launch β†’ Review β†’ Reach. Give each log a layer and see how far each thought has grown. SPIRAL GRAPHβ„’ See the density, depth and reach of your thinking on Log's own logarithmic spiral. Tap a layer to open its logs. WRITE MATH Wrap text in $ to show it as math, in your notes and in AI replies. Great for math and physics study logs. EXPORT AS MARKDOWN Export a whole folder as a ZIP of Markdown files, one note per log, ready for Obsidian and other apps. Back up and restore everything with JSON. PRIVATE BY DESIGN Your logs stay on your device. Log has no server and never uses your logs for training. Lock the app with Face ID. AI features use your own API key, stored in the iOS Keychain and sent only to the AI provider you choose. PRICING Free: up to 3 folders and 50 logs, with every feature. Pro: unlimited folders and logs. One-time purchase, no subscription.

About

Ambient Timer

Features
Read full description

A timer that creates space β€” for stillness, and for deep focus. Paired with field recordings and ambient film β€” crafted by a single artist, not a sound library. Sounds and visuals by Chisato Ohori, whose work has been exhibited at Kunstpavillon, a historic contemporary art gallery in Munich. Set the ring. Press play. Let time pass. Optionally, pair your session with field recordings or ambient film β€” or keep it in silence. When the timer ends, a break mode continues the same atmosphere, so the transition from focus to rest feels natural. A minimal ring interface. A gentle bell to close each session. And a record of every session, quietly accumulating over time. The timer, sound selection, and session history are free. Field recordings and ambient film are available with Unlimited β€” a one-time purchase of $2.99.
