Editor's Overview

OnTime - Presentation Timer is a timer application developed by jakobkreft, packaged as a single Android APK of version 3.0 weighing in at 1.33 MB. The package targets Android 4.1+ and above. Below you'll find the publisher's own description, a quick spec sheet, and a short buyer-beware checklist so you know exactly what you're installing before tapping download.

Install Checklist

Only download through the button on this page — never from third-party mirrors or shortened links, which are the most common way malware spreads.
File size is a light 1.33 MB, so it installs quickly even on modest connections.
This build is signed by "jakobkreft" — always verify the developer name matches what's listed on the app's official store page before installing an update.
After install, Android may prompt you to allow "Install from unknown sources" — approve only this one install, then revoke the permission in Settings > Apps > Special access.
We link directly to the APK file or the publisher's repository; we do not modify the binary. Always run a virus scan after any sideloaded install.

About this app

OnTime keeps speakers on schedule at live events, presentations and lectures.

Set a total time and two warning points, then start it. The whole screen is the signal: green while you have room, yellow when you should start wrapping up, red when you are nearly out. When the time runs out the clock keeps counting upwards, so you always know exactly how far over you ran.

Features:
- Total time with yellow and red warnings, each set as the time remaining.
- The background changes sharply between green, yellow and red — readable across a room.
- The overtime clock keeps running past zero.
- Save as many timers as you need, name them, and switch between them from the Timers list.
- The screen stays on while a timer is on screen.
- Rotating the device never disturbs a running timer.
- Everything fits on one screen. Nothing to scroll, nothing to hunt for.
- No permissions, no network access, no tracking.

Durations can be typed the way you think of them: 25:00, 90, 25m or 1h 30m.
