Would love them to fix ### 5/5 — Great app - could do with update *2026-04-13, version 1.02* I really do like the way one can customise a workout routine with this app including timers etc I do use it for relevant workouts to this day. However it’s not been updated in 6 years! ### 5/5 — Love this app. *2024-10-06, version 1.02* I’ve used so many timers & can attest that this is the best. I use this app every day for so many different purposes. You can fully customize your timer to speak, beep, count down, tell you how many seconds or minutes left, and the list goes on. And it’s so easy to use. To the developer: thank you for providing this app fully free. It truly deserves so much more likes & recognition. ### 5/5 — The best timer I’ve ever seen *2022-10-20* All the apps should be like this. This is a wonderful timer, I can write my circuit workout on a text file and then simply copy/paste in the app, that’s it! The timer is ready to run! **Developer response:** Thanks for the kind words and enjoy your workouts! Update Oct 2023: Just released new app ”WODbanger” - it has many same features as Ultra, but the workout after editing on iPhone, is executed on the Apple Watch. ### 5/5 — Most Flexible Free Interval Timer *2022-09-09, version 1.02* Clearly a lot of work went into making this app as flexible as possible. I’m surprised it has so little reviews here when other, simpler timer apps, are full of adds and in app purchases. The text-based instruction format can be a little daunting at first, but the instructions and examples are clear. Since timers are just specified as text, they’re easy to share with others. I also love that the timer UI allows me to “preview” the timer by skipping forward and back between steps. ### 5/5 — Simple and customizable ! *2021-02-01* I tried several of similar apps very briefly, this one is the only one that suited me because it is both extremely easy to use and 100% customizable to make your own programs as you wish, without any limit. I use it daily. Thank you for it :)! **Developer response:** Thank you for the nicest feedback! Update Oct 2023: Just released new app ”WODbanger” - it has many same features as Ultra, but the workout after editing on iPhone, is executed on the Apple Watch. ### 5/5 — I love this timer *2020-08-15* Great combination of easy to use and endlessly customisable. You can make a timer with any number of different lengths, label them and then get those labels read out to you throughout the timer via text to speech. There’s about ten help screens at the beginning of the app that make it seem like it’s going to be overwhelming but once you actually get into making your own timer, pretty much one button opens up the entire range of options in a very simple way. I do (untimed) burpees followed by yoga so I made a yoga timer with things like ‘get ready for ___ pose’ and then ‘start ___ pose.’ I use the UK English voice as I wanted a male and the Australian voice seems only to have female. I like his voice but it would be good to be able to access male and female voices of each language. But I can say that apart from this minor thing, the developer really does seem to have thought of everything a timer app could possibly need. But anyway, I love this app very much. **Developer response:** Thank You for the nicest feedback. Will work on the male/female thing too :). Let’s see... Update Oct 2023: Just released new app ”WODbanger” - it has many same features as Ultra, but the workout after editing on iPhone, is executed on the Apple Watch. Doesn’t talk though … ### 5/5 — Best workout timer I’ve used *2020-06-23, version 1.02* I used the previous version for years and I am very pleased to see this new version with even more features and flexibility. It’s the best timer for people who want workouts combining circuits with different timings; with untimed sets possible too. ### 5/5 — Absolutely perfect!!! *2020-01-12, version 1.0* I’ve been a long-time user of the other timer from this developer and have never found anything that comes close to it with flexibility and limitless possibilites—until now!!! This new timer is amazing!! And naming it a “timer” is just not enough, it’s a whole workout app. you can easily create your entire workout so easily and customize down to the color during different times! I just copy and paste my workouts from some of my online workout scripts, then adjust my times and off I go! Please note, this app on the surface may seem confusing but it’s not!! Just start using it, the instructions are clear! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
