It also deletes your weight loss progress which is frustrating. ### 4/5 — Helpful app *2019-02-11* Super helpful for anyone using this eating plan!! Can you build in an alarm mode setting for an eating reminder? ### 4/5 — Pretty great *2019-01-08* Love it, just wish there was a way to write down what foods you ate not just the containers and also to track when you go over ### 2/5 — Disappointing *2018-03-05, version 1.45* Okay if you only care about weight and containers. Without measurement tracking it was a big disappointment. ### 4/5 — Nice app, adaptable *2017-11-16* I like the way it helps count containers and you can edit workouts, so If your doing the counts with a different program you can still track. ### 2/5 — Needs a lot more *2017-07-11, version 1.45* Need to be able to click on food and it fill the container. Need to be able to find more foods on here as well. I would like to be able to view examples of daily foods. ### 4/5 — Easy To Use! *2017-04-05* I like using this tracker. It's easy to use and you can modify your targets. I lowered mine after realizing that it was presenting me with way too much food daily. I use it on my phone which is super convenient! ### 4/5 — SIMPLY GREAT! *2017-01-11* This app is the quickest easiest way to keep track of what you've eaten on the 21-day plan! AND you have a handy list of foods for each category there too! Super! Love it!!! ### 4/5 — Great tracker *2016-08-05* I like that I see what I have left to go as I use up (tap on) the containers Easy to use and can back date for anything missed. User friendly and has help with keeping a visual of daily intake on one screen! Well done. ### 3/5 — Good but can be better *2016-07-15* This app is good, but needs to be improved. You should be able to double click on the food and it automatically takes away the container. ### 3/5 — Loving it *2016-07-10* So I just got this app and I haven't been using it very long but I really like it. It makes keeping track of your containers so simple. Especially if you're someone like me using the 21 day challenge with just the diet using a different exercise program. I did give it three stars because the app is not fully accessible to VoiceOver users. The only serious issue I found was on the tracker tab the containers are presented to you as an image therefore for VoiceOver cannot read them. And there's no option to enter your containers manually. ### 5/5 — Very Easy *2016-06-16* So easy to use. Just getting started, I wasn't sure how much of what but just tapping the container was quick. The food list is also very helpful. ### 2/5 — Be aware! *2016-06-11, version 1.45* This app doesn't "roll" your measurements over when it switches to the next 21 day count! Gah! ## Most critical reviews (10 lowest-rated) ### 1/5 — Not free *2024-05-12, version 1.48.4* Not free… only a free 3 day trial ### 1/5 — A waste of money *2024-01-05* It said a free 7 day trail and my fault I didn’t read the fine print. It’s a three day trail. I didn’t like the way it was set up and there is a free one that I used in the past. My fault I thought they just updated the app and started charging people for it. ### 1/5 — Not cool bro *2023-01-27, version 1.48.4* When I upgraded the app just yesterday it is now telling me I need to pay 29.99 a month to enter weight and inches. When before the upgrade it was free… what the heck? No warning about the price difference in the bold text next to the upgrade button, otherwise I wouldn’t have done it and kept it the old version ### 1/5 — Paid for App for them to make it a subscription *2023-01-10* Paid for the app a few years ago, they decided to make it into a subscription service and did not reflect my original purchase. Disappointed in the app. ### 1/5 — Waste of money *2020-07-31, version 1.46* 4.99 is absolutely too much for this. I hate the way it tracks food. Can I have a refund??? ### 1/5 — Rate *2019-02-03, version 1.46* Would be easier if you could list food ### 1/5 — Lame app *2016-02-21, version 1.44* Needs more notifications etc ### 1/5 — Z *2015-06-12* Not very detailed ### 1/5 — Best 21 day app! *2015-06-02, version 1.1* I had a 21 day tracker app since January that ended... very sad very lost without it. I wasted days searching and trying apps to replace the one I had. I thought I would never find another 21 day tracker app that was complete until I found this one. Very thorough, easy to use and now I am back on track to finally take off my last 20lbs. I am almost glad the first app ended. The best $.99 I've ever spent!! thank you! ### 2/5 — Daily food containers *2023-05-26* I liked the older app better when I could see the food list with each colored container. It would encourage to eat certain foods I wouldn’t have thought of. ## Most praised reviews (10 highest-rated) ### 5/5 — I F***ING LOVE THIS APP! *2020-01-21, version 1.46* I’ve been wanting to try 21dayFix for a while but I never understood how to use it. I’m finally taking a chance and because of this app I am so happy and excited! At first I was thinking “what in the world do put in here? How do I know what it is I can actually eat?!” And BOOM! You guys have a list. I am sooooooo happy! Thank you thank you! I think I will be able to crush this weightloss journey this time around! 😎 ### 5/5 — I love this app *2019-09-05* I use this app everyday because it allows me to keep track of my vegetables, fruit, and water intake. I know exactly how much to eat and how often. ### 5/5 — Portion Control Diet APP *2019-05-29* Very user friendly and makes the program easy to follow. ### 5/5 — Keeping it simple *2016-12-05* I got this app on the recommendation of a co-worker. It's easy to tap the containers as I use them; I'm usually a paper & pen user. We all have our phones with us and helps me to track my food as I eat instead of waiting & possibly forgetting. It also tracks weight & measurements. It's a great app & would definitely recommend. ### 5/5 — I love this app *2016-10-19* I am using the cups diet and I am able to set up my daily program. Like I have said befor I would pay to sync to iphone ### 5/5 — Excellent App *2016-08-31, version 1.45* Makes tracking a breeze! ### 5/5 — Great! *2016-08-30, version 1.45* I especially like that I can customize my containers! ### 5/5 — Great app! *2016-08-01* Very easy way to keep track of my containers during the day. I like that it allows you to use half containers. Also easy to personalize the container counts and the daily exercise. Highly recommend! ### 5/5 — Great App *2016-07-15, version 1.1* Makes this program much easier! I can log on my phone now instead of paper. Great app:) ### 5/5 — User friendly *2016-07-02* This app is great. It is a completely doable way to eat. I like this app better than the 21-day app. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
