Increment feature doesnt work

Got this app to help with Smolov and wanted to round my weights to the nearest 5 lb increment, but it doesnt work. Also wish there was more functionality with each lift/set (like a place to take notes and the ability to change the weight if I have to modify). The only thing you can do is check off the set, saying that you did it. It would also be nice to know what the percentages are supposed to be and not just the weight based on your 1 rep max. Overall disappointed with this app. I didnt end up using it.
