❓ FAQ

How many timers can I run at once?

There is no limit. Add as many timers as you need. Note that very many timers may make the screen crowded.

How do I save my settings?

Press the 'Copy URL' button and the URL containing your current settings is sent to our shortening service, then the short URL is copied to your clipboard (the original URL is copied if shortening fails). Bookmark it or share it to restore your setup anytime.

What is Reverse Standby?

Enter your desired finish time and the app automatically calculates when to start. The timer begins counting down automatically when the start time arrives.
