You've tried every time-tracking app. None of them stuck. It's not you. It's the friction. Scrolling time wheels. Tapping through categories. Switching between "deep work" and "shallow work." By the time you've logged a session, you've lost the thing you were trying to measure. We rebuilt time tracking from the ground up. Speak, don't tap Press the Action Button on your iPhone, or tap once on your Apple Watch. Just say what you did: "Spent 90 minutes writing the proposal, took a 10-minute scroll break." On-device AI parses, segments, and categorizes it — automatically — into a clean Markdown file. Hardware-level frictionless capture Built natively around iOS Shortcuts. From impulse to logged entry in under two seconds. No unlocking, no app-opening, no category-picking. Your data never leaves your phone Everything lives in a local folder on your device. Not on our servers. Not in iCloud (unless you decide to). Not even visible to us. If this app disappears tomorrow, your archive stays intact — forever. Built on the Obsidian philosophy Under the hood, it's just a folder of Markdown files. Drop it into your Obsidian vault and your time data instantly plays with Dataview, backlinks, daily notes, and graph view. Any Obsidian plugin would love to do this — but plugins can't reach into iOS Shortcuts. We can. Built for: Knowledge workers who've abandoned every other tracker Apple Watch / iPhone power users Obsidian users and PKM enthusiasts Privacy-first, local-first believers Quantified Self practitioners Readers of Lyubishchev who want to actually see their lives The point of tracking time isn't to optimize yourself. It's to be honest with yourself about how you actually spend your one short life. Make logging feel like breathing. Keywords (English): time tracking, voice journaling, Obsidian, Markdown, local-first, Apple Watch, Shortcuts, quantified self, productivity, daily log, privacy, deep work
