I would stick to strength training made at its best, like it is now. There’s a ton of apps dealing with general fitness objectives and I wouldn’t enter in this red ocean. There’s risk to lose focus

Hi, are you sure your default exercise setting wasn’t set to rest pause? In that case there’s no issue

A quick tip: if you go to the calendar at the bottom of the home page, you can check what’s next in the following days. At any rate, a, b and c programs have always the same exercises and there’s no need to plan ahead every single week

Just to help 😊

Our body doesn’t recognize the week, so it’s not useful to have fixed trainings for every single day of the week. Our body does recognize only frequency. 
The ppl split is ideal for a frequency from 4 to 6 trainings per week. 3 would be too low. So, if your frequency is 5 times a week, ppl in itself would be perfect. The split you’re suggesting has the 2 leg days too close. Obviously what I say applies if you exert the right intensity to every workout…

Exercise sequence is meant to respect intensity placed on the right exercises. If needed you can change the order as you like, for instance if there’s queue at a machine or rack. If possible I try to respect the order to place the right intensity. I.e.: it has no meaning starting with a leg press and finish with deadlifts

Maybe it’s not all you’re asking, but if in the settings, in the custom rep section, you input 5 -20, the app gives you a wide array of rep ranges following your 1rm. I’m doing this and I’m quite satisfied

The feature you’re requestiing is already existing in the execercise setting. You can tweaks the increments

In medium and easy sessions it’s better to follow app’s suggestions. In the hard ones you can push to the limits. 
otherwise, in exercise settings, you can select ‘challenge’ in order to adapt more quickly

I confirm that after a two weeks break the app adjusted weights and reps to reflect a smoother start. My first leg day, in the medium version, was totally doable. Even the warm up was lighter than before.

I think the option it’s already and adequately covered

There are lots of caloric trackers around. Currently I’m using Yazio, but the most used in the world is my fitness pal. That’s why the best option would be to import data from the health app (Apple or android) that collect all data related to caloric expenditure and intake, no matter what nutrition tracker you are using
