Was loving it until *UPDATE!! It works again!!

NEW UPDATE: I ended up emailing the support staff about the issue I was having and one of their people was in constant contact with me until the developers were able to fix the issue. My Polar Fitness Band is now back to syncing with the app, and my activity data (i.e. calories burned) are showing up in the app again! I’m back to losing weight!! Thank you so much, Developers and Support Staff!!!


The app all of a sudden stopped working with my Polar Fitness Band five days ago. Now, my activity data (i.e. calories burned) won’t sync with the app anymore. I’ve tried everything. I unlinked/re-linked my Polar Band with the app. I’ve logged out and back in after changing the settings. I uninstalled the app and reinstalled it. Now, any time I try to link my band with the app, I get an Error message, and the app gets stuck on a page that says “Connecting Device” with a little circle going round and round like it’s “loading.” To get out of that screen, I have to exit out of the app, and when I go back in to the “Connect Device” page, it says my Polar Band is linked- even though it’s not! Been dealing with the for 5 days now. Very frustrating. The app is only useful for me to guide as a weight loss tool if I know the correct amount of calories I am burning, and thus what a true 500 calorie deficit is, so that I can aim for a one pound a week loss. Please fix!! Otherwise, would be 5 stars!!

Perfect for me!

I’ve always had a low BMI and after getting pregnant consulted with a nutritionist. I needed more protein in my diet so I started eating meat after being a pescatarian for a year. Unfortunately, the app they had me using was clunky and not very intuitive. At 18 weeks pregnant I was not gaining enough weight still so I searched for my own app and found this one. It’s absolutely perfect! It takes into account that I’m pregnant and let’s me adjust how much weight I want to gain per week if I want. It tracks the important stuff that I need to make sure my little man is getting everything he needs! And it’s soooo simple! I’ve created recipes with my daily shakes and was able to scan in all my vitamins. The copy and paste feature is perfect and the barcode feature is fantastic. I’ve been using for two weeks and have only had one item that the barcode didn’t recognize. I’ve never written a review on an app before but as of yesterday (after using the app for only two weeks) I am on track with my weight where I should be at 20 weeks pregnant and I couldn’t be happier that I found this app! Thank you for making something so easy to help people track their diet for whatever purpose they choose!!

App is getting buggier with every release

Pretty explanatory. Also, I feel this is one of those concepts that was amazing in the beginning and went downhill in time. I’ve used Cronometer from its early browser days- excellent since then at what it does. Since they expanded and grew, the made poor choices along the way. Firstly, the team is downright incompetent. Customer service/ support team is probably founder’s extended family/ friends or just unqualified for the job. Absolute garbage at handling questions, feature requests. Take a look on the support forums if you don’t believe me. Downright embarrassing. Secondly, whoever is in charge of the app probably learned coding in 2 months from online tutorials- which is not bad, just not good enough to charge money for. After years of requests from basic functionality like time stamps, they finally introduced the feature a couple of years back and immediate made it paid. I walked them through 2 errors they had made, but eventually just gave up when I realized they’ll never figure out how to properly integrate their app with apple health.

All in all it’s my preferred app since I loathed the big fitness tracker apps, but it’s basic database search functionality for micronutrients- the thing everyone used Cronometer for, has been there since day one. Everything else is just trash. Hopefully the founder decides to hire the right people soon, preferably talented professionals this time.

Developer Response ,

Hello there!

Thank you very much for providing all of this helpful feedback. We're happy to hear that you've been using Cronometer since the early days and we appreciate the support! We are sorry to hear that you've had an unsatisfactory experience with the customer service team - they are truly an amazing group of very educated individuals who actively try to solve every request we get in a timely manner!

Of course we would love to implement all of the feature requests we get from each of our users, however, our improvements to the app/added features are typically done based on what majority of the users want. In fact, we collect all of the feedback daily and use these to guide future iterations.

Again, our sincerest thanks for taking the time to send us your thoughts - I have forwarded them onto the entire team.

Have a great week!
