## What is One Hundred Hours?

One Hundred Hours is a timer for tracking practice, one skill at a time.

Pick a skill — an instrument, a language, a sport, a craft, code — and give it a target: 100 hours. Start the timer when you sit down, stop it when you're done, and One Hundred Hours keeps the running total. No streaks, no social feed, no account. Just the hours, logged.

WHAT IT DOES
• A live, on-screen timer for each practice, with a Live Activity so it stays visible when your phone is locked or you've switched apps.
• Set a target length for a session and see it right next to the live timer, so you know when you've hit it.
• Attach a photo to a session — a sketch, a set list, a scoreboard, a screenshot.
• Add a note to any session afterward.

YOUR DATA STAYS ON YOUR PHONE
One Hundred Hours has no login and no server. Every session, note, and photo is stored locally on your device. Nothing is uploaded, and nothing is shared. No ads, no tracking, and no in-app purchases.
