Counterintuitive user interface, confusing nonfunctional buttons, very versatile and useful – Time Tracker+ Task Manager Review

This app is a bit fuddy-duddy, and has not been updated in a long time. However, it gets the job done, albeit with some very confusing nonfunctional buttons and limited, counterintuitive entry methods. I am trying to use the "bedtime" template to track my rise time each morning. However when I tap the "Add current time" to the journal entry field, this does not update the time field in the upper right-hand corner. The user is forced to manually click and type in the time. Otherwise, the time will not show up on the monthly calendar view for tracking purposes. Unfortunately, the task of manually entering a time presents new challenges and limitations. For example, if I type in 500, this gets interpreted as minutes, converted to hh:mm format and shows up as "8:20". Or I would need to type "7" ":" "0" "3", to get 7 hours, 3 minutes. There is no way to indicate a.m. or p.m. for these entries, which I suppose is not crucial, however it would be nice. After all, it is possible to get a.m. and p.m. in the journal entries, so why not in the main data entry field in the upper right-hand corner? The plus and minus buttons do not serve any function in this template, which is confusing. When I press them, my data entry gets deleted and replaced by a "+" or a "-". It is a steep learning curve for such a simple app, and the functionality is still lacking in many ways. It is a promising app because of its versatility – it is a great idea to have an app that can track just about anything. However it needs some re-tweaking of the user interface, as well as some serious rethinking about the various ways in which people would want to use an all-purpose tracking app.
