## What is 15 minutes - An idea of Alex H?

I watched a viral Alex Hormozi reel about tracking your time in 15-minute intervals to become aware of where your hours actually go. Instead of creating yet another spreadsheet, I got out of bed and challenged myself to build an app.

15Minutes helps you log what you're doing throughout the day in simple 15-minute time blocks. No complicated features, no overwhelm — just tap, type, done.

✦ Log activities in 15-minute slots
✦ Get gentle reminders every 15 minutes (reply directly from the notification)
✦ Set 3 daily objectives to stay focused
✦ See where your time goes with visual stats and streaks
✦ 8 beautiful themes to make tracking feel less like a chore
✦ iCloud sync across all your devices
✦ 100% private — your data stays on your devices

The goal isn't perfection. It's awareness. Once you see where your time actually goes, you can't unsee it.

Built as a weekend challenge, now on v[X] with improvements based on real user feedback.
