Crash on vivoactiva 3 please fix

December 2, 2018 | Version WorkItOut v2.3-upd6

Would be awesome if it didn't crash after the first 40 seconds on vivoactiv 3

November 2, 2018 | Version WorkItOut v2.3-upd6

On ne peut pas reprogrammer les zones de fc et l'appli ne prend pas en compte les valeurs réglées dans les paramètres utilisateurs . Fenix 3HR

Very happy to finally find an app that's fully customisable for my HIIT workout on my Fenix 5, it alerts you when to start/stop and could tell you what your next move is according to your input in Garmin Connect. I really love it so much! Thank you developer for this awesome work! ♡

It doesn't work on vivoactive 3 music. When it switches over to the rest or next activity, it shows an IQ logo with an (!) exclamation Mark. Some bug somewhere. Would be nice to have it to work on this device. Thank u

Great workout app. Customize your workout and take it wherever you go. This is my favorite app!

Application seems good for interval training but is not useable for tabata training as working round is mini 30s. Mayne can improve the apps without limitation and the apps could be wonderful. Best Tjierry

I use on Forerunner 235 and works perfectly, very pleased thank you! Only thing is I like to mix up my circuit/interval training, but I can't figure out how to create and SAVE different circuits of exercises, so that I can quickly choose which circuit I want to do without going through and individually changing each exercise each time I want a change. Is this possible? If not would make a great addition to an already excellent app. Thanks!

Leider funktioniert die App nicht auf vivoactive 3. schient Potenzial zur einer Lieblings-App zu haben. Bitte reparieren

March 9, 2018 | Version WorkItOut v2.3-upd4

i use vivoactive 3 , its cant work . :(

Hello, I installed your App on my garmin 735xt version 4.3 everything works fine but does not save the activities on garmin connect or on the Garmin you have some advice thanks

Currently crashes after a few seconds. Also unable to set a working time less than 30 seconds which isn't ideal. Similarly must do a minimum of 3 exercises. Was planning to use it for repeated bike sprints. 20 seconds work, 40 seconds rest, update would be great along with fix of current crashes

Theoretically, it's a great app but it doesn't work most of the time. When it does though it crashes after the first exercise

January 9, 2018 | Version WorkItOut v2.3-upd

Works great as long as you don't change anything. Phenomenal Concept and exactly what I would be looking for but I've tried to uninstall and reinstall a number of times and every time I switch the exercises or the time per round it will not open on the vivoactive HR (if it does by chance open it'll close after first exercise). I'll definitely be checking back in hopes of an update that'll fix this.

Yes it did crash on Fenix 3 with 8.5, but it works great on 8.61. Pause/Resume and Quit and Save both work again w/o watch resetting.

December 16, 2017 | Version WorkItOut v2.3-upd

I used the app a lot. But now it crashes each time if I select save and exit after my workouts. I have the fenix 3 with software version 8.50.
