Oztai Harbor

Oztai Harbor is a quiet on-device organizer for the small repeating moments of the day. Four tools share one calm dark interface and work entirely offline. Quick Notes lets you anchor a thought the moment it surfaces. Type the line you need to remember, add an optional tag, and the note stays in your private list on the device until you decide to remove it. Checklists lets you build small, named groups of items for the days when several little things have to happen together. Pack a bag, gather things for a trip to the shop, or track progress on a small project; tick items as you complete them and the count updates instantly. Pocket Timers offers a row of practical presets plus a custom builder for any minute and second combination you need. Start, pause, and reset with a tap. A short chime plays when the timer ends, so you can step away with your hands free. Unit Converter brings together four everyday categories: length, mass, volume, and temperature. Pick a category, choose units, type a number, and the result appears live. The last conversion is remembered between sessions, so frequent jobs feel natural. The app runs without any sign-in, account, or remote sync. Every entry stays on the device, can be removed at any time by clearing the app data, and the experience continues to work in the same private offline shape from one session to the next.
