All that is promised is a timer. That’s all it is.
However for something that just counts down, it is buggy. The final countdown sound as the clock approaches zero keeps playing when we try to stop the timer. Forces a reset to fix.
Why not include rules? A scoring aid? A virtual player sheet? A reference guide? Anything more to make this app actually useful.
Also: an initial setup/construction guide. How to organize pieces in the box guide. Score tracker. So much more could be included!
