So much potential but just doesn’t work

I mean literally does. Not. Work. Data appears and disappears at random, things take forever to load (if they load at all). I completely sympathize with the fact that it’s just one developer doing everything here and that kept me using this app for longer than I would have otherwise, but after a week of infinite refresh/retry/reload, I’m just too frustrated by this app to keep going.

Response from developer

Hi! I'm really sorry to hear about all the issues you've been having. The latest updates resolve most of these issues and there's an announcement going out soon to explain what happened. I hope you come back and give Zolt a chance again, there's a lot of great stuff coming up!

Ugggh

I want to love this app. It has everything I want in a fitness/meal tracking app. The problem it only works for me about 25% of the time. It freezes or gets hung up adding items and then I have to force close it. I have a goal to track my meals every day and it’s already a struggle for me because I find it incredibly boring. When I try to use this app and it takes me about 5 minutes before I can get the correct things to load I’m not going to do it. I’m pretty disappointed. Especially since I paid for a year subscription.

Stopped working

I really loved this app but now for more than a week all of the features I use do not work AHA level, heart rate zones, cardio load, and adjusted maintenance calories all stoped working. They all get stuck in a state of loading and will sometimes flash until a second until the whole app freezes. Making it useless.

Hi there! I'm sorry you ran into syncing issues! Most of these issues should be fixed in recent updates.

Data nerd’s dream come true

Simply put, this app tracks so many variables and creates near real time analyses on how those variables impact things like your TDEE, sleep, recovery, energy levels, etc. Easily worth the money.

I haven’t used the in app AI for food tracking yet, but I use a separate AI to help me meal plan and track all my intake, then provide me end of day totals in nutritional label format which I use Zolt’s nutrition label scanning feature to input it as one meal at the end of the day.

UI is not always intuitive but workable. Instructions are sparse and it can be buggy sometimes but the developer is *extremely* responsive and seems genuinely enthusiastic about integrating fixes and adding more features.

Great concept poor execution

The app is buggy beyond belief, it doesn’t import macros stored in Apple health all the time and when it does it’s not accurate.
