Why can we not see whether or not there is a wait list until after booking? And how hard would it be to let me know how many are on the list in front of me? I use Red Effect as a supplement to other workouts, so the details are important, like type of class and wait list status - but conspicuously and frustratingly absent with this app. Please update!!! ### 1/5 — MrMarathon 26.2 x3 *2020-12-14, version 5.0.5* the booking on this app is really bad. especially when i am trying to book in advance. there needs to be some drastic improvements ASAP! ### 1/5 — Love RE; WORST App Ever *2020-12-12, version 5.0.5* Red Effect is great but the booking APP is awful and extremely frustrating to use. It only works part of the time, freezes, super slow, not intuitive or easy to use. It should show the class format (strength, ess, etc.), if there is a waitlist for a class AND where you are in the waitlist so you know your odds of getting in or not. Hope they upgrade this soon. ### 1/5 — Waitlist & notifications needed! *2020-11-03, version 5.0.5* Have belonged to similar boutique gyms where apps show waitlist number. Also would like to be notified if I get off waitlist and into a class, especially since I will be charged a no show fee. Would also like to see what type of class is offered, ie, Strength, Endurance, etc. ### 1/5 — Please update *2020-09-14, version 5.0.5* Not intuitive and does not show if classes are full and where you are on the waitlist. ### 1/5 — Hard to reserve spots *2020-09-11, version 5.0.5* When selecting a class, I have to click about 3 different places to get to where I need, and then be put on a waiting list. It would be nice to see how many people are in the class already so I know if I have even a fighting chance of getting in. Then after selecting a class, it kicks me back to an information screen, I know what I’m signing up for, just let me do it. ### 1/5 — No Availability *2020-09-08, version 5.0.5* It just lists the class schedule and doesn’t show availability. So you have to sign up for a class first to see if it is open. Not at all helpful to plan out my schedule. If I do get into the class, then I have to go back and cancel the ones I am waitlisted for. Would rather be #2 on the waitlist for the class I want rather than in the class I have to adjust my schedule around. ### 1/5 — App is not great *2020-09-01, version 5.0.5* Love this place but the app is not very helpful. Needs more info regarding signs ups, where you are on the waitlist as well as slots available in a class/sauna before registering. ### 1/5 — Hasn’t worked in weeks *2019-06-20, version 5.0.1* Can’t book a class without calling the studio, and this has gone on for over three weeks. How long does it take to fix an app? ### 1/5 — Doesn’t work *2019-06-10, version 5.0.0* Can’t log in. That would be a start. ### 1/5 — Workout is amazing, app is terrible *2019-06-03, version 5.0.0* There are always glitches! Right now I can’t even book a class or log in. Also why can’t you pick a bike for cycle or see your post workout stats on this app? It’s so frustrating! ## Most critical reviews (10 lowest-rated) ### 1/5 — Difficult to navigate *2022-01-12, version 5.0.5* Hard to see /navigate I wish I could see waitlist and transparency of where I am on the waitlist ### 1/5 — Terrible App *2022-01-12, version 5.0.5* I would really like to be able to see the waitlist and where I fall on the list. ### 1/5 — Worst app ever *2021-08-03, version 5.0.5* Worst app ever. It’s always “temporarily unavailable” and when it does actually work the filter option tends to disappear. It doesn’t have a continuous scroll so it pauses when it reaches the end of the page. It doesn’t show the class capacity or waitlist number. It’s very archaic and needs someone with a brain to fix it or create a new one. ### 1/5 — Needs updates *2021-07-29, version 5.0.5* This app is extremely poor quality. You cannot see whether or not your on the waitlist until after you’ve signed up, you cannot see if the class is full, how many people etc., you cannot even see how many people are on the waitlist. Held the time I get a 503 error message that the app does not work. This needs to be updated to reflect the quality of the workouts and studios which are top notch- this app on the other hand is definitely not ### 1/5 — Great Workout - Lousy App *2021-07-08, version 5.0.5* Love love love the Red Effect workout and facilities, but the App needs some major revision/updates. Sone suggestions are: - I’d like to be able to book a class and a follow-up sauna on the same screen. As the App is currently configured the user has to back out and book each activity separately. - Every time I book a sauna I’m put on a “wait list” but never know how many others are ahead of me in the queue. Very frustrating. - When booking a fitness class I’d like to know how many others are already signed up. On the positive side, I do appreciate knowing who the fitness Coach will be when I schedule. There is real potential to make this App as great as the Red Effect workouts and facilities. Please get ‘er done! ### 1/5 — LOVE the classes; app is outdated *2021-04-23, version 5.0.5* The app is super outdated, my only request would be to show the number of people in each class & how many are allowed total (for example if 8 registered in a class of 12, it would look like 8/12). Also, if there’s a waitlist, for it to say full & have the number of people in the waitlist. ### 1/5 — APP out of the 80s *2021-04-10, version 5.0.5* It feels like using an Atari, very basic, no feature to see how many people in front of you, just says waitlisted. Would be good to see what kind of workout it’s gonna be (2G or 3G) ### 1/5 — Not useful *2021-03-06, version 5.0.5* I can not see if any classes are available or waitlisted until after I sign up. So I have to sign up cancel and sign up then cancel to see if I'm in a class. Please show availability and then place on waitlist. ### 1/5 — app needs work *2021-02-10, version 5.0.5* i love the workout. the app however is poorly set up. it would be much better to know about the workout i am signing up for, and also if it showed where i was on the waitlist or roster. ### 1/5 — Wish it was easier to navigate *2021-02-10, version 5.0.5* Workout is great but wish the app was more transparent such as seeing how many spots are available for classes, seeing where you are on the waitlist, and what the workout is ## Most praised reviews (6 highest-rated) ### 5/5 — Great studio *2018-05-08, version 4.0.0* Great app Great studio Amazing instructors especially Mandi Exceptional management Andrea and Steven ### 4/5 — Sync with IOS calendar *2020-01-04, version 5.0.5* It would be great to have the app sync with iOS calendar so you don’t have to keep going back into the app to check your class time & day. ### 3/5 — Booking App *2020-09-09, version 5.0.5* Love the app. Don’t have many problems with it. My only request would be for it to show if the class is wait listed before joining. If there is a waitlist, show the number we are on the waitlist. Also, if wait listed for a sauna it be nice to be on a master list vs. joining a waitlist for all saunas at the same time. Overall, the app gets the job done. Just friendly suggestions :) ### 3/5 — Suggestions for fixing app *2019-06-22, version 5.0.1* Nice to have the app back. If developer can fix the rubber banding so the entire app doesn’t rubber band when swiping hat would be great. Also can you get the functionality to pick a bike and see where you are on the waitlist? Just some suggestions for the app, otherwise, love the gym. New location is great. Thanks all! ### 2/5 — Updates to the app made it worse *2023-05-23, version 5.7.0* I cannot see what classes I have already booked without looking at every single day individually, you can not see instructor names just first initial. It will no longer show you past classes taken. ### 2/5 — Poorly functioning app for an otherwise good brand *2022-01-07, version 5.0.5* I’ve been a member of red effect for a total of 3 days and I’m already sooo annoyed with this app. Functionality basics I would expect from a fitness studio app: - ability to add registered class to calendar (this is HUGE!) - see waitlist status - calendar view for registered classes - track workout data, point/ earned, number of classes attended, etc. - see if a class is waitlisted before signing up - see packages and billing/receipts Please, please improve this programming. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
