1. 5/5The best interval timer

   Exactly what I needed. I’ve never had a good internal clock and I frequently get lost in reps and rounds and go too hard to make up for rounds I think I’ve miscounted. Using a normal timer didnt help because I would have to reset it every time and that brought me out of it. This free app is insane. There is a halfway notification for each workout. Learning to lift with shoulder injuries I’m doing 10s on and 10 off and I thought it would be difficult to find a timer to accommodate such a small amount of time but nope. This still gives halfway markers for even that small amount of time. You can name workouts to keep you on track if you get lost like me. I wish I could give a thousand stars. I’ve used it once and I’m in love already. I already know this is going to attribute to muscle gain and weight loss. THANKS DEVS!! Edit: Free version only lets you do one workout a day which is not a huge deal to me but probably would be to some. 3 bucks a month or 20 bucks one time for life could be a good deal depending on your finances and how often you work out. I do not have the finances for that so I’ll just make one longer workout and try to count if I decide to do a second workout in a day.

2. 5/5Great App Design!

   I’ve been looking around at apps that have a timer like this and this is the only one that truly fits 94% of my needs (which is leagues better than others!). With this app you can set how many exercises you want, NAME THEM (!), set your rest time in between your working time, set your round reset, and decide if you want a voice or beeps to tell you your progress! I like how you can see a history of your working out too. It really only lacks two things (that are very small). When naming your exercises, you can’t add one in the middle of the list so you would have to edit the one in the middle and shift all the other down (which is only a problem because I cultivate my own workouts and it only takes a minute max. to fix it). The other is that I can’t mark a rest day so I would lose my workout streak. Otherwise this app is literally perfect! I love the aesthetic of the user interface too!

3. 3/5Almost perfect but…

   This app is simple and user friendly but it’s missing 2 features to really be 5 stars: 1) being able to save and name the timers. History is cool and why not but it’s not as useful as saving and naming timers, especially if you need several timers saved but you do not use them daily. Like Full Body workout would be easier to find in “saved timers” that looking at the details of all the history to find the correct workout and then repeat it. Way better to go to saved, look for the one with the correct name in an ordered list that allows shorting by most recently used, alphabetical, used most times, longest, etc and include a find function 2) Being able to name the different “work” and “rest” portions, not only useful for workouts that have similar exercises but also for job routines: instead of work, rest, work, rest; it could be crunches, rest, run, cool down or instead of work, rest, work, rest; it could be filing, coffe break, sending reports, stretching. It just takes that out of you mind and let’s you concentrate on the task rather than trying to remember what “work” you have done and which one you should be doing next.

4. 4/5Well designed with a couple of flaws

   This intervals timer is nicely designed and flexible enough to meet most of my needs. I like the balanced amount of information it displays and the layout and color choices that make the interface easy to read. Two gripes: clearly the decision to forgo a favorites menu — or some similar feature to let you save and select specific workouts from a list in the sidebar or something — was intentional. This would seem to be a very basic feature of an app like this, and the devs instead direct you to choose from the history log of previous workouts instead. This is pretty annoying for me because I use one short workout for a lot of things so that one is over represented and one that I only do every couple days ends up quite far down the list. Please consider adding a favorites menu or saved workout section besides the history log! Also, a bit more flexibility would be appreciated in the warmup feature. 5 seconds would be nice, or why not let us use the same picker as for workout and rest sections?

5. 5/5Spoken words, doesn’t change my music volume

   There are other apps out there that let you define all sorts of hyper-custom regimens and skins and fonts, but at the end of the day, they all have three fatal flaws. (1) they use beeps instead of words. (2) they don’t have warnings that you’re 3 seconds away or halfway done. (3) most importantly, the beeps change the volume of my music. This app doesn’t affect the music volume at all, and uses a countdown at 3 sec before each beginning and end, and says “halfway there” which is really helpful too. So I can overlook the fact that I can’t define lots of custom time intervals and save multiple workout schemes. I mean, all I really need is “do 10 sets of 30 sec with a 15-sec pause between each, then reset the equipment for a minute and start over.” And this does it.
