bombClock is an app that uses a timer to motivate children to complete any task. Just set the desired minutes and seconds and press the bomb, the timer will start. When the task is finished (getting dressed, brushing teeth, etc.), you can press the Stop button and a positive point will be added to the history. If the time ends without pressing the button, a positive point will be added to the explosion score. The timer will tell you every 30 seconds how much time is left until it reaches the last 10 seconds, at which point it will start a countdown. I hope this app motivates your children to carry out different tasks. bombClock is free to try for 30 days. After that, unlock the full app forever with a single one-time purchase — no subscription.
