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.

Verdict
The clearest difference is in-app purchases: Sabolog at none against Log's 1. Log's advantage is ads (none vs shown) and update cadence (every 4 days vs every 3 weeks). On price and device support there is nothing between them.
