Sleep and recovery

Last update fixed some lag but broke adaptive TDEE, TDEE history, and nutrition sync.

Last update fixed some minor lag but unfortunately completely BROKE TDEE. My entire TDEE History chart is now blank and it’s miscalculating my TDEE by 1000s with the Zolt adjustment also heavily inflated. It seems the issue is it’s no longer registering any entries for weight or food logs since it’s suddenly saying there’s not enough history - shows 0 entries entered for this week and last - despite the fact that there are logs for all the days going back a year. And I’ve tried syncing to force a correction in all the ways possible - pulling down, syncing option in TDEE section - except nutrition sync in setting section because that’s broken too. Every attempt made is quick to say sync failed. I really don’t understand why every update is worse than the last. I’m beginning to wonder if any thorough test runs are done prior to these updates being submitted. Bummer because this was a good app when I first subscribed to it. And I can’t even export my nutrition data to go elsewhere because it only lets you export weight history, and clearly nutrition data was not syncing to the supposed server anyway since the sync is broken.

Hi! I'm sorry you ran into this issue. This issue affected a small subset of users with the last update and it should be fixed now as soon as you update to the newest version. Again, really sorry - feel free to email me at hi@zolthealth.com too!

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.

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.
