I really wanted to like this, and even paid for the full version hoping that the extras would provide what I needed, but am disappointed. My needs are pretty simple: I want a 1 minute countdown timer for between sets in the gym. Nothing more complex than that. But I do want it on both phone and watch. This app provides both, as well as a widget and a dynamic island and lock screen version, so once running you can always see it. Great. However, the phone and watch versions are separate. You can't set the timer on one and see it on the other, there are two discrete versions of the timer, which isn’t really what I wanted. Also, the watch version has to be set each time, you can’t just start a preset like on the phone. Secondly, and most importantly, there’s no haptic alert, ie vibration. You either have to have an audible alarm (who wants that outside of your house?) or else you to visually check the phone regularly. This, sadly, makes it almost useless.Lastly, and weirdly, when the timer gets to the end it just carries on going in reverse - ie it starts counting upwards. No idea why. So you have to manually stop it every time. I have to admit I regret paying full price for it now, though I’m sure these things could be fixed. There are a million timer apps but I’ve yet to find one that does what I need, strangely.
