This app is a timer that can measure multiple elapsed times. As an example of use, when you are feeding your baby breast milk and infant formula, you can quickly check how long it has been since the last feeding. You can also measure various things at the same time, such as sleeping time and the interval between taking painkillers after childbirth. As another example, it can be used to manage study time for each subject, such as math or physics, or multiple cooking times during cooking. To use the app, tap the "Add new task" button, set the name and color, and you're ready to go. Tap the play button to start measurement. It is a simple structure that the measurement is completed when the stop button is pressed. Double-tap a task to edit its name, color, start time, and more. In addition, the free version can measure two elapsed times at the same time. If you want to set 3 or more items to measure, or if you want to hide advertisements, please consider purchasing the premium version in the app. ---------------------- Terms of Service and Privacy Policy: https://akikibai-labolatory.jimdofree.com/privacy-policy/

Elapsed Timer's advantage is ratings volume (6 vs 1) and device support (3 vs 1). On price, in-app purchases and monetization model there is nothing between them.
