  1. [R9] Noom Weight Loss 3/5 · US Too gamified now: This is my second time doing Noom; the first time was a great success, and this time around started off great with a bang. But then an update hit the app a couple of months ago that made it nearly unusable. The gamification has been taken to the extreme and it seems like I can’t log a meal without 5 pop-ups to shower me with affirmation, seeds, and lightning bolts, and then anoth
  2. [R12] Noom Weight Loss 3/5 · US Good but: It’s generally very good but has been very glitchy lately
  3. [R54] Noom Weight Loss 3/5 · US Great, but….: The app is great at teaching and tracking more than just food. But the database for scanning barcodes needs a serious update. How can I reach my “green” food goals if I’m constantly having to manually add what I’m eating because it’s not in Nooms database. I shop mostly at Costco, Kroger, or Safeway. So it’s not like I’m buying unheard of products.
  4. [R78] Cal AI 3/5 · US Great App - But Needs Improvement: First of all, the aesthetic of this app is fantastic. The AI is also shockingly accurate. HOWEVER, the food database needs a drastic improvement. If you travel and you have to eat out a lot, easy things like a McDonald’s Burger with no bun are not in this system. There’s an only a few fast food items and they all seem to have odd names associated with them. Im gi
  5. [R6] Noom Weight Loss 3/5 · US Program great - app awful: The program and mindset is fantastic but the app is terrible. It takes forever for it to actually load. You have to sit there and watch a box spin aground for minutes on end. I’m currently going on 11 minutes waiting for it to load.
  6. [R19] Noom Weight Loss 1/5 · US Terrible design, annoying daily usage: Out of all the apps on my phone this is the one I hate using the most. It is slow to load, there is no customization of the order of the dashboard screen. It is tediously slow to log a meal. There is no shortcut from the desktop to log a meal. They have tried to gamify it and have you submit seeds at night, which is totally pointless and requires unnecessary
  7. [R28] Noom Weight Loss 2/5 · US Not so good weight loss tracking system: I got this using the upgraded app and finally decided to continue with the no paying option- terrible!!! You can’t track your exercises. To enter any item you have to go through multiple screens and hit done like three times- just not user friendly. Also, if you have a meal on repeat, unless you make it into a saved meal, you can’t just repeat the lunch fro
  8. [R63] Cal AI 3/5 · US Synch issues: I really like this app after using MyFitnessPal for years I tried Cal AI and I really like it a lot. The issue is the sync to apple health is unreliable. It syncs some entries and not others. so until they figure that out I’m going back to my fitness pal
  9. [R3] Noom Weight Loss 3/5 · US Latest update buggy,: erases recorded data every evening, water that had been manually recorded and steps, both day’s auto goal and steps completed uploaded from Fitbit. health tab will no longer connect even after multiple reboots.
  10. [R24] Noom Weight Loss 3/5 · US App works when it works: The app has a lot of power, but it is not easy to find things. It often doesn’t work where you just get a lot of spinning when you try to open it. In addition, the Support people don’t even know where things are or what is available or not available. You get different answers from different support people when you ask a question. Noom needs to boost its support and fix all
  11. [R67] Cal AI 2/5 · US Freezes a lot: I give this app a 2, it’s great when it works but it’s freezes constantly. Please fix the freezing problem!!
  12. [R1] Noom Weight Loss 2/5 · US What happened?: I used to use Noom pretty regularly. I got frustrated because one day when I clicked on the app, it made me log back in and provide all my biometrics again. That happened twice and after the second time, I didn’t have the time to complete all the specifics anymore, so I stopped using the app. I use the free version because I couldn’t afford the subscription. After several months,
  13. [R4] Noom Weight Loss 1/5 · US Scam!!!: This is a scam! I cannot possibly believe that the positive reviews here are real! They will not allow you to cancel. They will continue to charge you. The user support function does not work. They will not respond to my correspondence through any other means. I may have to take legal action
  14. [R22] Noom Weight Loss 1/5 · US Charges for cancelled subscription: I cancelled my trial subscription within the allotted time and was still charged over $100. Stay away from this company!
  15. [R61] Cal AI 1/5 · US Misleading Trial offer!: When I clicked 3 day trial it charged me 29.99. I tried to reach out to customer service and they didn’t reply.
  16. [R31] Noom Weight Loss 1/5 · US Awful customer service: Given that this medication is so powerful, it is their responsibility to have even basic customer service to support clients. They do not. Prepare for your account to get mishandled over and over again. Loved the app, their call center and long delays in response to serious issues is horrific.
