Glitched

UPDATE 9/16/26:
I like this app. The problem in my earlier review was resolved. I’ve logged a few days of meals, and I’m finding the AI features helpful in unexpected ways.

Using my previous logged meals, it identified where nutrition gaps may be hiding, and suggested meal ideas.

The flare tracker is especially helpful, it would be cool if you could write in your own symptoms to track.

I’ve used many apps for dieting and nutrition, never one that suggests meals based on nutrition gaps.

Another complication for me is that I’m dealing with some gastritis, so I can only tolerate bland foods. It might be cool to include a meal planner or nutrition analyzer that can take that into account.

But the AI chat did respond to my questions about bland foods and recommended I consult a doctor for gastritis.

Overall, I really appreciated the developers responsiveness and the new and unique features!! I plan to keep using it!


9/8/26 Such a great concept! But I signed up for the free trial and it said “payment processed; failed to log in. Try restore purchase.” I clicked restore purchase and it said “error. Try again later.”

I’ve now tried again three times after waiting a few hours in between.

I guess it’s still new and glitchy? Too bad.

Response from developer

Update Oct 14th - Will work on updating the flare tracking. Will also let users add the condition so meal recommendation takes that into account. Thank you ---- Thank you for trying Klenz, and I'm sorry, that's not the experience you should have had. Can you please try again as we patched an issue recently. If you still run into an issue, please reach out using this link and let me know the email you used, and we will sort out the issue ASAP for you: https://klenz.app/support. Thank you Klenz Support
