How are you supposed to follow when this happens on every exercise. I have had this app a long time and it didn’t used to be this way. ### 2/5 — App used to be good. Not sure what happened *2026-02-05, version 5.104* This app was my go to, I used it for literally everything. Now the animation no longer functions so I can’t see how any exercises are performed. ### 2/5 — App keeps crashing *2024-02-01, version 5.104* Unable to do any of the premium workouts. When I try to start one app crashes. Only able to do free workouts even though I purchased premium. However app does instantly crash after one of the free workouts is finished. Super bummed. Please fix! ### 2/5 — Needs an update *2022-12-01* Really like the routines in this app. It hasn’t been updated in a while. It used to keep track of workouts. Doesn’t now. It crashes after the workout is completed. ### 3/5 — Crushing and info deleted *2020-11-11, version 5.104* I used to love this app until 5 days ago. It started crushing after the work-out and then I uninstalled it and installed it again and my data got deleted! I am still using it because I feel it is an app that understands me. Workouts are short, not rush, either “too much” or “rough” (at least the ones I use). I like it but fix the crush and try giving me my data. Thanks! ### 3/5 — Love it! Needs maintenance *2018-12-28, version 5.104* I use this everyday Changing it to 3 stars since it does not adjust the display properly if using an iPhone XR or any phone with the notch. Still love the app though. Is there a replacement app? ### 3/5 — Average *2018-05-12, version 5.104* The workouts section contains routines that Sequence exercises in a variety of ways. Still, you can’t create an automatic custom routine like in other apps that don’t require a monthly subscription, neither do the workouts change automatically as you progress from a beginner to other levels. I will give then that fact that the include resistance bands, bodyweight and dumbbell routines. Check out the Lolo and the Daily workout apps. ### 3/5 — I was a little apprehensive *2018-04-30, version 5.104* Changing my review to 3 stars. Two things would bring it back to a 5. One- the fit test input crashes the app. Meaning, if you start a plan workout schedule, you take a number of fit tests to track your progress. Where you go to enter the results crashes the app. Never have been able to enter anything there yet. Two- watching the video workouts and listening to the Apple Music app on a Bluetooth device makes the music really staticky and not enjoyable. Allow 3rd party music to play through the app better. Thanks! I was a little apprehensive at first about the app purchase to unlock some stuff plus an annual membership, but I really am really glad I tried it. I’ve done this for two weeks. First week was app purchase of different workouts and I like the variety that I could choose based on time I had and traveling I do. Then I decided to try the membership to have a plan. I am one week into a work out plan and I feel great and already can tell a difference. I also like the meal plan. Two recommendations. It would be nice to see your upcoming workouts ahead of time. Currently you don’t know until the day of. Wish the meal planning and calorie intake would work with my fitness pal app. ### 5/5 — Versátil *2017-09-19, version 5.104* Excellent, adapts to different physical states and places to perform the exercises. Some problems to link it to the app that measures the heartbeat (Heart Rate). I can't link :( Excelente, se adapta a los diferentes estados físicos y a lugares donde realizar los ejercicios. Algunos problemas para vincularlo con el app que mide los latidos del corazón ### 5/5 — Love it *2017-09-18, version 5.104* Amazing app ## Most critical reviews (10 lowest-rated) ### 1/5 — Buggy and out of date *2025-09-21, version 5.104* This app appears to not have been updated in a long time. The animations and images for the workouts to load. ### 1/5 — App crashing *2025-07-08, version 5.104* I paid for it why is it crashing ### 1/5 — I have just wasted £4.99 purchasing this app *2025-04-05, version 5.104* I purchased this app because after a recent update to the Argus app, I could no longer record a bespoke workout session. The details within the app store prior to purchasing the app suggested, suggested that I would be able to manually record a workout session. It does not. The videos that show how to complete an exercise do not load. A previous update to the Argus had removed the option to repeat a workout that had already been recorded. I will be cancelling my subscription to the Argus app (£22.99) and investigating other fitness apps. ### 1/5 — Doesn’t record workout stats. Premium service took my money. *2023-02-23, version 5.104* Your app crashes just because the wind is blowing. I use it because the workouts are great, but are you ever going to fix it? The premium service not only took my money, but crashed and was never accessed. Twice. Your program integrates into Argus, and that’s the only reason I still use it, but FIX THE PROBLEMS! ### 1/5 — Doesn’t work anymore *2020-12-01, version 5.104* Loved this app. It just crashes with the new updates. Lame. ### 1/5 — Stopped Working *2020-11-22, version 5.104* I purchased the Premium workouts for £28/- and they have stopped working and I have been running from pillar to post to either have it fixed or receive a refund ### 1/5 — Impossible to create your own workout (or at least far from obvious) *2019-09-11, version 5.104* I give up. How do you create your own work out? ### 1/5 — Paid for what? *2018-05-14, version 5.104* I bought this app in 2013 and had all the features. A few years down the road they remove workout sharing, remove section labels in workouts and put subscribe buttons everywhere. This is not what I paid for. Azumo doesn’t care because they don’t even respond to my communications. ### 1/5 — No abre *2018-01-20, version 5.104* iPhone SE 128Gb. Eliminado y reinstalado -> crash. ### 1/5 — I actually would like the ap, if it would work *2017-12-30, version 5.104* I did the yearly fee for the premium program, and have been charged by Apple, but it doesn't work. I emailed customer support, no response. So, right now, I'm leaving this review and hopefully someone will respond. ## Most praised reviews (10 highest-rated) ### 5/5 — Needs an update *2025-12-05, version 5.104* Really like the routines in this app. It hasn’t been updated in a while. It used to keep track of workouts. Doesn’t now. It crashes after the workout is completed. ### 5/5 — Do it daily for a six pack!! *2023-12-13, version 5.104* I only use this for the core workouts but anytime I stick with it, I know I’ll end up with a six pack with only twenty minutes of work a day (actually less…closer to 17 minutes)…works like a charm and works your full core! Have used this app for almost ten years and absolutely love it! ### 5/5 — Great app *2020-10-16, version 5.104* This is one of the greatest apps ever and I think they discontinued it. Not sure. ### 5/5 — Instant Fitness *2020-03-18, version 5.104* I love it - no matter what sort of fitness you need. There’s something for everyone . Start gentle and build, but only when you’re ready. 😀 ### 5/5 — Very useful *2019-05-08, version 5.104* Use it faithfully great workout regimens ### 5/5 — Good *2018-02-23, version 5.104* All the workouts I need ### 5/5 — Fünf Sterne! *2018-02-20* Super Workout-App! Die App ist übersichtlich und bietet ein breites Angebot an Übungen, die nach Muskelgruppen kategorisiert sind. Die Sprachanweisungen sind auf englisch, was ich nicht störend finde, da die Übungen gut dargestellt werden. ### 5/5 — Great app *2017-10-04, version 5.104* Easy access to a load of effective workouts ### 5/5 — Great app *2017-09-25, version 5.104* Great for on the go quick workouts or add a few together and get a great total body workout ### 5/5 — Effective *2017-09-25, version 5.104* Helps keep me accountable. At age 73 with minor back arthritis keeping an active basic workout schedule is the key to keeping a quality of life.
