Simple Stopwatch & Timer

This application contains two simple, but very useful tools: stopwatch and timer. Only minutes and seconds are used, which is sufficient in most cases. No ads. No in-app purchases.
When you start the application, the tab with the stopwatch opens by default. Switching between the tabs of the stopwatch and timer is carried out using the lower navigation bar.
HOW TO USE THE STOPWATCH.
Pressing the START button will start the stopwatch. In this case, the button itself will change its appearance and the inscription on STOP.
Pressing the STOP button will stop the stopwatch (the button itself will change its appearance and the inscription on START). If you then press the START button again, the time will continue from the moment it was stopped.
Pressing the RESET button will stop the stopwatch and reset it to 00:00.

HOW TO USE THE TIMER.
Set the required time interval in minutes (no more than 60) and seconds using the visual element for choosing numbers.
Pressing the START button will start the timer. In this case, the button itself will change its appearance and the inscription on STOP.
Pressing the STOP button will pause the timer (the button itself will change its appearance and the inscription on START). If you then press the START button again, the timer will continue counting from the moment it was paused.
Upon reaching the specified time, the background of the application will turn yellow, a beep will sound and a text alert will be displayed.
Pressing the RESET button will stop the timer and reset it to 00:00.
