KEEPER
Read full descriptionHide full description
This app tells you the time by voice every 10 minutes. There are only two buttons to use: start and stop, so it's easy to operate. It speaks for 4 hours. Ideal for running and training. ---- This app uses the iPhone/iPad notification function. Therefore, you will need to allow "sending notifications." Also, due to the nature of the app, it will not work properly in an environment where notifications do not arrive at the correct time. Please be careful if you are using focus mode or sleep mode. Please note that the app will not speak if the sound is on silent mode. To avoid any problems, it would be helpful if you could check the operation before using it in real life. This app does not have a reservation function. You must launch the app and register an alarm before using it. To customers using Apple Watch Voice notifications will not be available if the app is linked to an Apple Watch. If you want to hear the voice, please unlink the Apple Watch.

Verdict
The clearest difference is price: NotificationTimer at Free against KEEPER's $0.99. KEEPER's advantage is ads (none vs shown) and update cadence (every 4 days vs every 3 weeks). On in-app purchases, device support and iOS requirement there is nothing between them.
