Timer issue ongoing

I did the app update via the Play Store as advised and followed instructions provided. Timer still going at 180 seconds.

That solution would work. So long as the app calculates based on the actual weight the user enters rather than its recommendation.

I agree. I use metric so often I can't use the suggested weights because our metric dumbells don't have the "right increments". The metric dumbells and plates we have go from 10kg > 12.5kg > 15kg >17.5kg > 20kg etc (+2.5kg each time) and the plates we have are 1.25kg and 2.5kg then 5kg, 10kg, 20kg, 25kg.
