The ones at the top are all correct! ### 4/5 — Add option for writing name of exercises *2025-02-14, version 3.0.0* App is good, but it will be more helpful if i could write down name of each exercise I am planing to do… ### 4/5 — Very good in use with her program *2024-04-11, version 2.0.4* Really like this app for timing it’s great when using for its purpose of doing her programs as it’s all timed perfectly! Only flaw is that I WISH there was a fastforwd button to skip to the next set/rest ect. Sometimes I’m on a time crunch and want to skip the last round of each set or have much shorter breaks so that would make it a solid 5 starts for me! ### 4/5 — Useful for ebooks but would add one thing. *2023-12-20* I enjoy using this timer along with Sarah’s ebook (I have the Body & Bump as I’m currently 33+ weeks pregnant.) My only suggestion would be to add a 20 second rest period in the custom timer. For the cardio section it says to do “30 SEC ON 20 SEC OFF) there is not a 20 second option, just a 10 or 30+. I’ve been doing 40 seconds on 10 seconds off. But it’s frustrating to have to watch the timer so closely to make sure I’m resting after the 30 seconds of activity. ### 2/5 — Frustrating *2023-02-01* I love Sarah, but this app is so frustrating. The set timers for her ebook workouts are easy and great. The biggest frustration there is that if you accidentally slide the screen or tap back you cant go back, you have to start the timer all over. Reaaallly annoying when you’re deep in a workout. My biggest gripe is the custom timer. For reference i have the pregnancy ebook (along with others) but one of the workouts she suggests using the custom timer bc the timing is really specific. But setting up the timer is so confusing. There are no instructions, just all these sliders with 1-10 or 1-5, labeled “circuits” “rounds” “workouts”. Honestly i cannot figure out which controls which and after resetting it wrong like 5 times its just so annoying. Could use a lot more work to make it user friendly and not so frustrating to use. ### 3/5 — A little misleading.. *2022-10-26, version 2.0.4* Thought it was workout sets, a bit misleading ### 2/5 — App crashes *2022-06-08, version 2.0.4* This is so nice for the workout in the ebook, but the app crashes in the middle of working out almost every time I use it. ### 4/5 — Almost Perfect *2021-11-19, version 2.0.0* This app is quite handy but would really really benefit from an Apple Watch option. ### 4/5 — Please add 20 sec rest but GAME CHANGER 🤍 *2021-09-19, version 2.0.0* Love this I use it ALL the time even for my own workouts. Only wish I could do 20 sec rests between each set on the custom timer! Would be a game changer! ### 4/5 — Handy! *2021-09-04, version 2.0.0* A simple and well designed timer app, I really like it. The only thing missing I think is a summary screen at the end of a workout. It would be satisfying to just see the total workout time and circuits completed. Otherwise, great! ### 4/5 — Custom Timer needs more settings *2021-08-26, version 2.0.0* I love the app, I just wish there were more time intervals to choose from the Custom Timer. I would like to run with the app, but the exercise time only goes to 120s where I wish it could be longer to adjust to my fitness level. ### 2/5 — really not the best *2021-02-16, version 2.0.0* really confusing to set up a custom timer. doesn’t ever explain what each preset timer means or how long the workout is. which when just quick glancing to do your own workout you really want to know not well designed. voice is intolerable and doesn’t make any sense half the time ### 3/5 — It doesn’t line up right *2021-02-01* It was working fine, then all of a sudden, it doesn’t tell me the 3 second warning until the next round of workouts happen. Tbh... I don’t think these glitches should be happening for an app that was actually purchased with money... just my opinion. Love Sarah and everything she stands for but app issues have been occurring for a while now and I wish it didn’t bug out like this!! ### 2/5 — Glitching a lot recently *2021-01-26, version 2.0.0* I’ve been loving this timer but it started glitching a few days ago. I’ve uninstalled and reinstalled the app but it’s still not working properly :( ### 4/5 — Total time *2020-10-21, version 2.0.0* I really like this app and have had no issues but it would be good if the total workout time was listed especially for the custom timer. Also having more rest/workout time increments would be helpful. ### 4/5 — Love Sezzy her Ebook but the timer doesn’t work right *2020-08-17, version 2.0.0* I bought the ebook and am on my second round through and the timer still hasn’t been fixed. The sweaty shedder is not working for the 7th exercise. ### 3/5 — sarah’s voice cuts off *2020-06-01, version 2.0.0* i love the idea of hearing sarah’s voice reminding me which exercise i’m on, counting down, announcing break, etc, but for me her voice gets cut off every time ☹️ ## Most critical reviews (10 lowest-rated) ### 1/5 — It’s a timer! *2023-07-20, version 2.0.4* The images for the app are misleading with images of workouts. Obviously it is a timer and is designed for another product. Shame that the images are misleading. ### 1/5 — Update Glitches *2020-11-18, version 2.0.0* After I got the update, the app has been having all kinds of glitches . The most common glitch I have been noticing is that it just skips breaks and jumps to different parts of the timer. ### 1/5 — Could be better *2020-10-07, version 2.0.0* This app is helpful, yes but could be a lot better considering it’s an app you pay for. It’s literally just a handy timer that fits with the work out you’re looking at. It would be good if there was a section where you could tick off your progress, and see where you’re at with the program. If it told you what exercise you were supposed to be doing instead of just saying “exercise 1” that would be helpful too. I found myself having the book open at the same time as the app but I feel like the app could’ve told me the extra info I needed from the book. It’s only £1.99 so it’s alright but I’d rather not have spent it for what I got. It’s a shame because her book and workouts are really good! ### 1/5 — Disappointed *2020-05-26, version 2.0.0* This app is just a timer so if you purchase Sarah’s ebook you have to go back and forth from the ebook to the timer to see what exercise is next. Thought the app would tell you what exercise is next to make it more convenient. ### 1/5 — Timer sporadically stops *2020-05-15, version 1.1* The app is essentially a glorified timer, so would expect it to not stop sporadically when in use... ### 1/5 — Glitchy af *2020-05-14, version 1.1* Stops/cuts out occasionally if you exit out of the app (ie. to look at the ebook on your phone) so if it feels like your 30seconds is going for a minute, it probably is (and yes, timed it against another timer to check) ### 1/5 — Extremely disappointed *2020-04-14, version 1.1* I’ve paid for the timer and the times are wrong and doesn’t work properly. Can I get a refund ### 1/5 — Good idea but there are a couple of glitches *2020-04-08, version 1.1* The timer shuts closes down mid way through round 3 specifically. It doesn’t allow background music some days, I have to press play on the music after Sarah talks. It’s a really good idea and will be great if it worked. I find it frustrating when I’m mid way through workout and I realise the timer has shut down/ paused then I have to wait for it to catch up meaning my flow has gone. ### 1/5 — Crashes on iPhone 11 Pro *2020-04-03, version 1.1* Always crashes and during workouts which is SO annoying because you lose progress 😑 ### 1/5 — Timing is off/stops timing randomly *2020-03-24* Can’t believe I paid for this. What a ripoff with the free timers out their. Updating my review because it’s so disappointing they haven’t updated it or responded to any of our issues at all. I love the idea of the app, particularly the custom timer but the time is off. For 30 seconds comes out 35 or 36 seconds. The longer the time the more off it is. Also it just randomly stops timing and I’m not sure what the pattern of when/why? These honestly seem like relatively simple fixes so I hope this can get fixed and it’s a great app. ## Most praised reviews (10 highest-rated) ### 5/5 — Love it *2026-05-25, version 3.0.0* Very useful ### 5/5 — Love it!!!!! *2025-04-20, version 3.0.0* Downloaded it during lockdown and still use it to this day at least twice a week for my workouts. I have the sweaty shredder programs too but the timer works fantastic for your own workouts too! Can only recommend. Plus side: works dreamily in conjunction with your music. ### 5/5 — Absolutely LOVE! Aesthetic and effective *2023-09-20, version 2.0.4* Honestly I use this for stuff outside of Sezzy Workout plans now and it’s so versatile. I’ve gotten all my friends to start using this app as well :) ### 5/5 — Great simple app *2021-11-22, version 2.0.0* App worked so well in the background. It’s simple but it does what it says it does - times your sets for your workouts. Sure it’s $3 but you’d easily pay $5 for a coffee and only enjoy it for 15min. This app you have forever, so I can’t understand why people are complaining. ### 5/5 — Easy to Use *2021-03-17, version 2.0.0* I use this timer app with Sweat It to Shred It and often I use it for personalized workouts. It would be EPIC if there was a way to save my custom timer settings. ### 5/5 — Must have! *2021-02-10* This timer is a must have for the ebook workouts! It makes the workout so seamless, and effortless to just put in your headphones and let the timer go. It works perfectly over music, and continues even after you close your Lock Screen. You have to buy this timer!! ### 5/5 — Absolutely Amazing!!!!!😁😁😁 *2020-09-27, version 2.0.0* This app is so incredibly amazing! I have always wanted to time and create my own workouts! This app is the best!! Highly recommend to anyone wanting to up there fitness Routine!!!!! ### 5/5 — Amazing! *2020-08-06, version 2.0.0* The timers are so simple and I like that it’s already figured out for me. I have also used these timers for running sprints and my own creations at the gym. The app has taken the frustration out of all those other interval apps where it takes an hour to set the whole thing up and sometimes never works. Well worth the money! Also Sezzy’s voice is the icing on the cake :)! ### 5/5 — Works!! *2020-06-04, version 2.0.0* The most recent update seems to fix all bugs that were contributing to inaccurate timing and music issues. I love that I can use multiple apps simultaneously (e.g. Spotify and the Sezzy timer) with no interference to the timer. This app is the perfect accompaniment to Sarah’s ebooks and your own workouts. Highly recommend. ### 5/5 — love this app sezzy!! just some potential upgrade ideas *2020-05-29, version 2.0.0* i absolutely love the design of the entire app, it’s so stunning. just some ideas for the custom timer, i would love the ability to save custom timer settings for better ease of use. big love 💞 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
