## What is CompSim?

CompSim is your ultimate competitive speedcubing timer. In an official cubing competition, you don't do individual solves⁠⁠—you solve in an average of 5, mean of 3, or best of 3 format. CompSim streamlines this mode of practice by giving you the capability to practice like this and visualize your progress from this perspective.

Not only that, but CompSim allows for you to set a target, or a time to beat. This allows you to work toward a certain goal, like your official personal best (PB) or your long-term barrier. 

When you win (or lose), you get to the experience acted out by a cuber of your choice!

CompSim has plenty of customizable, intuitive features to make the user experience better than any other cubing timer, period. From WCA inspection and timer update to custom holding time and a beautiful dark mode, you can make your CompSim experience unique to you.

Of course, CompSim comes with the standard capabilities of any cubing timer⁠⁠—scrambles of all types, on-screen timing to the nearest 0.01, stackmat timer entry, and penalties are all included through a beautiful interface.

### 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.

### 5/5 — Loving the app!

*2023-07-10*

This is a really fun app! Love being able to set a target goal and seeing the result.

### 3/5 — Stats

*2023-06-08, version 2.1.0*

My PB is 1.52 single but it shows under best average

### 5/5 — Awesome!!!

*2023-03-13, version 2.1.0*

Idk

### 5/5 — BEST CUBE TIMER

*2022-12-19, version 2.1.0*

this is the most official app in store，no any error

### 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.

### 5/5 — CompSim Rocks

*2022-02-16*

Everything here is amazing! You get your full fifteen seconds of examining time, change between sessions and swap out your cubes, get celebrations of famous fibers when you break your average, and more. I hope CompSim excels with even more awesome cubing apps like this one.

### 5/5 — Good

*2021-12-31, version 2.1.0*

It is so good a cow would not eat it

### 5/5 — Bug

*2021-07-14, version 2.1.0*

The timer works perfectly but now whenever I open the app it just crashes and I have lost access to all of my times right now. Can you help me with this. I reinstalled the app and it happened again

### 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.
