Hello all, For a number of years I have used the simple NHS BMI Tracker app to enter my weight daily. This app appeared to be abandoned from the word go, was never updated for iPhone 5, nor seemingly even for retina display screens. I put up with it, as it was the only simple app I could find that didn't include food tracking etc. Anyway, I got an iPhone 6 and it no longer works properly. What I am looking for is a simple app that when I open it, I can type in a passcode and then immediately type in my weight. The only other feature it should have is historical data/graphs, and as I'm coming from another app, an ability for me to enter dates in the past. I don't use apps with ads, so if it is paid that is fine. Thanks!
