Ratings and Reviews
Amazing app! Extremely versatile. I had this one complex circuit, and I was like, “how am I gonna be able to do this with this app”. I was thinking it’d be long and tedious and not even perfectly correct. I thought I was right, but then I discovered the compound timer and the ability to copy and past exercises!!! Just when I thought I’d reached the limit with this app, I discovered an awesome functionality that makes things sooo much easier. It’s such a cheap price to get the whole thing unlocked considering how amazingly versatile and easy to use this app is. Sooooo worth it. The only little issue I have with it is that sometimes the timer sound glitches. So for example, like sometimes when the time for rest is down to just 3 secs, it does the 3 second countdown (which is great cause it acts as a warning and gets you ready), but sometimes it’ll start glitching out so there might be one beep then no more until the times up then you get one irky prolonged beep. It’s just a minor issue that only happens sometimes with me, but it just throws me off a little in my workout. Of course, that’s just me. Other than that, Amazing app!!!! Totally recommend!
As long as you find a good rhythm in your timed activity schedules (the timers that you make in this app), this app is great for helping people who have ADHD. It is soooooooo great because it displays the current activity on your full screen(so whenever you forget what you were supposed to be doing, you can look to your phone and it will tell you), it can play different sounds while you work (I like to use a ticking clock or classical music to calm me down), can be used for ANY activities you’d like, and has so so much customizability! You can have breaks in between your activity sessions that give your brain a break and still don’t count towards your total time worked on the activity. Also, you can use the app as a stop-watch kind of free-form timer: Press the next activity for when you feel that you want a break from the one you’re on and select “Allow-Overrun” for letting your sessions run until you’re done with your task. Love it! I just wish I had the mind to use it for more stuff😅
One of my favorite apps EVER
I know it’s super nerdy to list a timer app as one of my favorites ever, but this app is AMAZING. If there’s a paid version, get it! (I have had mine for so long, I think I was either grandfathered in, or I just ended up buying it when they upgraded it.) A few years ago I started experimenting with apps to help organize my life, and this one is surprisingly versatile. I use it in several ways: to schedule a full day of to-do’s where time management is crucial, for a short list of daunting tasks that are more manageable with time limits (pomodoro style), for multi-step mundane processes (brewing coffee, etc), for exercise intervals, yoga sequences, you name it. As a musician, it helps me organize my practice time. Also, the user interface LOOKS GREAT. It’s simple, but I love all the color coding and customization available. I have several timer apps and organizational apps, and this one is the most robust and customizable for time management. YAY, Seconds! Good job, developers! Thanks for making something so helpful!
