Sum Review

I bought Sum to be able to track my push-ups, sit-ups, and miles on a regular basis. So far so good, but, of course, there is always room for improvement.

• I would like to see a more responsive + / - buttons. Yes, they do their job, but their delay sometimes throws me off.

• It would be very convenient to have access to adding and subtracting from the lock screen in the widgets.

• Sometimes I do the exercises in larger or very small amounts and when I put them in Sum, it takes me a while to get to the number. Perhaps the option for increments of .5, 5, or 10?

Overall, I’m really enjoying the app and like the graphs and the history features.

Simple counter and tracking tool

Thanks for the tiny but mighty tool to track attendance records! If you add direct number input, it would be very practical for larger numbers. +- button on hundreds are very time consuming.

Developer Response ,

Thanks for the review! One way to add large counts to an event is to go to 'All Instances’ on the event’s page, where the + button menu lets you directly type any number

Love the app but!

Can not contact developer & app crashes when I try to delete a task and won’t delete.
