This isn’t the biggest deal but I just wanted to say that. I still love the timer! ### 5/5 — Best *2020-08-18, version 2.0* For me this is the best cube timer The target feature just makes it more great ### 5/5 — really good *2020-08-17, version 1.2.3* i like it a lot but i recommend that you and a feature to see your full session avg like cs timer and a feature to see what you need to achieve your target ### 5/5 — Good job *2020-07-15, version 1.2.3* Thank for this porduct rabi ### 5/5 — Very poggers *2020-07-13, version 1.2.3* Thanku rami ### 5/5 — Great timer *2020-07-12* This is a great Cubing timer with fun features, it would be even better if it would measure more stats like ao12, ao100, and more. ### 5/5 — Fantastic work, but one bug I want to point out *2020-04-29* There was one bug I had encounter with the timer. Whenever I stop the timer on an exact number like a 7.00, 8.00, or a 9.00 the first number always displays as one minuses by the number. For example if I stopped the timer at 8.00 it displays 7.00. Although it registers as a 8.00 but it might be nice to solve this little display bug. ### 5/5 — Awesome *2020-04-22* Some suggestions though. 1. Sometimes I put in the wrong target (mean to put in 1:15, end up getting a 1.15 second target lol) would be nice if we could alter the target post run. 2. Being able to move runs would be nice. It’s unfortunate when I do a one handed run under my normal 3x3. I know I can delete it, but optimally is like to move it to the other session. ### 5/5 — The timer is slow *2020-04-05* Edit: timer is fixed! Was pretty fast fix too I was really excited to use this and the app was working perfectly, but about 15-20 solves in- the timer started going really slow. I got three sub-10s in a row when my PB is 9.8 when I ran it alongside another stopwatch the timer was 6 seconds behind when it reached 10seconds. The actual stopwatch was at 16 seconds when this timer reached 10 seconds. I tried force closing the app but it didn’t work. I hope you fix this soon **Developer response:** Hey NameMinusActor, we've fixed this slow timer issue in the current version! Check it out! ### 5/5 — Update *2020-04-01* the timer issue has been fixed. good timer! **Developer response:** Hi tolya7777, we've fixed this issue in the current version! Check it out! ## Most critical reviews (10 lowest-rated) ### 1/5 — The scrambles are bad *2020-05-03* Although is a unique timer and i was very exited to use it, I am disappointed. the scrambles are much easier than normal. and the square 1 scrambles don't even work. it will give me a scamble that doesn't turn for example this is a scramble i got, (-5,-4)/ (0,-3)/ (0,3) /(-3,-3)/ (3,-2)/.... as you can see you cannot turn a kite in that dirtection. and this happens consistently. because of this and many other small bugs, i simply would rather use a timer like chao timer. ### 1/5 — Slow *2020-03-30, version 1.0* The timer is super slow 1 second is like 2 seconds ### 3/5 — Stats *2023-06-08, version 2.1.0* My PB is 1.52 single but it shows under best average ### 3/5 — Crashing on IPad Pro all of sudden *2020-08-28* Great app I love how it is different from the other timers out there. I been using it for about a month now with no problems and all of sudden yesterday the app crashed and now I get go back into it. I have restarted my iPad and everything and it is still crashing. Hope this problem could be fixed soon ### 4/5 — Solid *2024-06-14* This app is solid. Having the draw scramble feature is nice. Helps limit the number of solves I do at times. However, at least once a week, sometimes more, the settings reset and I have to reconfigure them. It’s not the end of the world, but annoying. ### 4/5 — Crashes when displaying PB *2022-10-03* I really like this timer overall; if I could add something though, it would be an option to upload your own photo for displaying cubers when you finish a set of solves. As of writing this review, my best single solves aren’t showing (it just displays as 0:00), and if I try to view it the app crashes. I don’t really hold this against the app though, as bugs happen and the timer is great besides this issue. ### 4/5 — Screenshots Crash It *2021-03-22* I love the app so far, but taking a screenshot crashes the app every time. Annoying to get a great solve and go to screenshot it and have it lost forever. ### 4/5 — Ok *2020-07-23, version 1.2.3* It’s perfect besides you can’t make you r target over 1 min so on events that takes you over 1 minute you can’t make a target ### 4/5 — Most of the reviews are fake, but here is my opinion *2020-06-12* The bad scrambles review for the square-1 WORKS I can’t believe there are so many rumors about this app, anyways onto the actual review. The timer is a bit slow, inspection voice I wish it was better sounding and the scrambles on the Megaminx make no sense maybe they might but I originally used Chao Timer for Megaminx scrambles. But since it takes cubing to another step, I’m giving it an extra star. It’s a really good game and if you keep on doing daily updates like these, then I think this is a new best timer for cubing. Overall, this app gets a big solid 4.5, but since you can’t do that, I will give it a 4 because of multiple glitches. It is a good cubing timer app though, I think the cubing community should have some more timers like these, and add some more exciting things added in like sharing a PB to a friend. I recommend this timer, if you are a beginner, or if you are sub 10. Just a saying though, I like Chao Timer a little bit better. It has less bugs but the only thing it doesn’t have on iPad is inspection time. So I’m looking forward to this cubing timer as well. ### 4/5 — Great game, one suggestion *2020-05-04* This game is awesome since I am going to my first comp in June and I am not prepared (lol) but here is a suggestion to make the game even better You can make warmup time with the same 1 minute limit. When someone presses the button “ready” they would be shown the scramble. Update: now whenever I get a flat time like a 7.00 it +1s it. I get a 7.00 in 2x2 but it counts it as 8.00. Please fix this. ## Most praised reviews (10 highest-rated) ### 5/5 — Loving the app! *2023-07-10* This is a really fun app!
