It’s zoomed in so the sides of the app aren’t accessible. ### 2/5 — Fix it please! *2020-04-14, version 2.3* I’ve loved these apps before and had them on other phones but now, I went to use it and it’s zoomed in really close and you can’t use it. Please fix so I can continue using! ### 1/5 — Doesn’t work properly *2020-04-05, version 2.3* The calendar shows up too big. Unable to click day one to start the challenge. ### 2/5 — Bug *2020-03-29, version 2.3* I’ve previously has this app on older devices and it’s worked perfectly, like the other reviews mention it keeps you motivated and there’s pelwnty of rest days in there so you don’t over work yourself!! However, since being in a relationship I’ve gain a few too many- happy fatty definitely! So with the isolation I’ve turned to motivation at home and these apps are great for it!! But I’m Gutted as one review has already mentioned that the page where you track your progress seems to be ‘zoomed’ in to fit the whole screen of the iPhone 11 generations! I’m gutted about this is the case for all of the 30 day challenge apps!!! Please please pleaseeee I hope this can be fixed ASAP!!! ### 1/5 — app not compatible with iphone 11 *2020-03-26, version 2.3* you can’t click on the first challenge on the iphone 11 and therefore can’t go to the next and complete any of them. ### 1/5 — Does not work with XR *2020-02-21, version 2.3* This app does not fit the screen of an XR. DISSAPOINTED ### 1/5 — Poor app *2019-07-12, version 2.3* Does not work for XR. The calendar is wider than the screen so I can’t choose the right date ### 2/5 — Crashes since last update *2018-03-16, version 2.3* I loved this app prior to the most recent update. Now every time I open it to do the day’s workout, it crashes. I even tried deleting and re-installing. It’s disappointing. ### 1/5 — App stuck on day 4!!! *2018-01-06, version 2.2* I can’t get past day four because all of my 30 day apps (I have them all) are not working on my iPhone X ### 1/5 — Kills music playback *2016-01-01, version 1.0* Unlike their other apps there is no option to schedule reminder for this one. If you have music playing this one will shut it off when you open the app. ## Most critical reviews (10 lowest-rated) ### 1/5 — Issue with calendar size *2022-08-19, version 2.3* I used this app before I got pregnant and loved it now I’ve had my baby and am ready to start working back out and I like to do cardio first and figured I’d use this app again since I’m working out from again (Covid was the reason before) but when I click on the calendar it’s like it’s large and doesn’t show all the dates in a small enough setting so I can’t even click on day 1 to begin. I tried deleting and re downloading and nothing.! I tried contacting support and it took me to a 401 page. I’m pretty disappointed cuz I was looking forward to using this app again ### 1/5 — Bug *2022-03-27, version 2.3* When opened, the app only displays half of the screen that is supposed to be displayed. Meaning you cannot click on day 1, meaning you cannot progress through the days so the app does not work. Same for all these 30 day apps by this company. Disappointed, I was excited about using these. ### 1/5 — BUG *2022-01-29, version 2.3* all your 30 day apps have a big it is zoomed in and unable to use the apps at all unable to click on days as day one is not in screen ### 1/5 — CALENDAR TOO BIG *2022-01-10, version 2.3* Cant even start day 1 or any days because the calendar is way too big. ### 1/5 — iPhone 11 *2021-02-10, version 2.3* It doesn’t fit in my phone. It’s zoomed in so I can’t press day one to start so I can’t even complete any of the activities ### 1/5 — App doesn’t work *2021-01-16, version 2.3* For some reason when I downloaded and opened the app the screen is almost like it’s zoomed in and won’t allow me to select ANY days to exercise! This is the same for all of their fitness apps as I have tried them all. Not sure what the issue is with their software or what?...weird. I have used this apps in previous years and had no issues which is why I’m not sure why now they seem to be broken ### 1/5 — Not working on iPhone 11 *2020-12-23, version 2.3* I’m giving this app a one as it doesn’t fit my whole screen and I can not press the days I want. Please fix this ### 1/5 — Can’t Start *2020-12-02, version 2.3* The calendar is too big for my screen and I can’t even start day 1. ### 1/5 — Can’t do day 1 *2020-06-08, version 2.3* Everytime I go to the app to check it out I try to open day 1 but I can’t cuz the screen is a glitched mess DO NOT DOWNLOAD THIS APP ### 1/5 — Won’t load *2020-05-13, version 2.3* Cannot load day 1 challenge on my iPhone 11 so app is useless until fixed. ## Most praised reviews (10 highest-rated) ### 5/5 — Great for the workday! *2023-01-29, version 2.3* I downloaded all 8 of the 30 Day Challenge apps. I set them to rotate reminding me so every hour one of them says to get out of my chair and spend a minute or two exercising. It’s great. They are short but effective at making me less sedentary…I am at a desk 8-10 hours a day. I can already feel the results. My muscles are showing more definition. The cardio doesn’t wind me like it did at first. I really like that there are levels so each 30 day challenge gets harder. A few coworkers have started joining me. Just a great fun little app! ### 5/5 — Fitness *2021-01-25, version 2.3* I LOVE this app! I always wanted to work out every day but gave up, this app was great because it has different levels. It got me motivated to get up and work out in the morning!! Truly awesome app! ### 5/5 — AMAZING! *2020-12-27* I am absolutely in love with this app! ### 5/5 — Get yo body movin *2020-04-17* Great set of apps. Really motivating and simple for beginners who want to workout in their bedroom & get the body they dream of. Good luck! ### 5/5 — iPhone 11 *2019-10-01, version 2.3* Could y’all make all of the apps compatible for the iPhone 11? ### 5/5 — So simple anyone can work out *2019-03-13, version 2.3* It’s just the push I need to establish a habit. Easy but effective. Rewarding check off stars. Love it. ### 5/5 — Excellent *2017-06-26, version 2.2* Excellent for motivation and quick workout. ### 4/5 — Really like it, but at times I think it is too difficult *2023-06-19, version 2.3* I downloaded this app years ago and honestly it helped a lot! It definitely worked. One thing that I do have to say is, is that I think it increases the intensity of the workout too fast. I think about this with all their apps. Other than that, I really like it! ### 4/5 — Awesome free app *2021-02-10, version 2.3* Always thought that an App to remind me what to do would be great, and this is one of those... except better!!! It targets specifically the areas that you need to work on to gain or define specific muscles. I’m doing 5 of these 30 day challenges, and so far, it takes me less than 30 minutes to complete them all... and they’re starting to get harder, but I’m also feeling my muscles forming and busting through that thick layer of skin and fat. Only complaint is the diagrams showing us what to do, sometimes it isn’t very clear when compared to the spelled out descriptions. In the end, a video of an instructor doing the exercises would help. Looking forward to what 6-months can do, one-month at a time... ### 4/5 — Good app but... *2017-01-15, version 2.0* The exercise daily are abit easy for a daily routine I need do 3 or 4 days for a decent sweat. I do intermediate and go gym 3 times a week. Overall a good app if ur just looking to start getting fit! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
