## What is RC Timing?

This App has been created by an RC Cars and slot cars hobbyist (myself) that had a need: I wanted to know my lap times when practicing in my local club but the expensive Timing System was not installed. So I created RC Timing.

RC Timing is an App that tracks lap times for radio-control and slot cars. It can be used in both indoor and outdoor tracks. 

This App is not intended to replace your club’s timing system. It is thought to help you in situations where you want to practice and the local timing system is not available. 

It uses the video camera for tracking the car colors and it offers an easy and intuitive configuration.

### 5/5 — Brilliant app!

*2026-02-03, version 3.6*

I use this app for hosting Rally events on gta online. It’s really really good! It works by colour which is perfect for what I need it for. At first I didn’t get the set up in the race session, but it’s pretty straight forward. Before you press start, go on setup. Align your camera at the start and park whichever car you’re setting up in shot. In the colour tab, Click the part of the car with the colour you’re picking. Then in the threshold tab adjust the tolerance until you can only see the section of the car where that colour is lit up. Then adjust the threshold to where the point where the bar turns from white to green then drive out of the camera shot and back in to make sure it activates. Do the same for all the cars and voila!

### 5/5 — Garage Floor Mini Z Timing!!

*2025-04-25*

This is a great app for timing our Kyosho Mini Z cars in the Garage floor. So far it has been completely accurate even running off one of the colours of a multicoloured livery. Pitstops have been great fun too!

### 4/5 — No sound on internal speaker

*2025-02-02, version 3.6*

There is no sound when not connected to bluetooth speaker

### 3/5 — Straightforward. Needs some attention.

*2024-09-09*

It seems like a good app but when you make the car a certain color it doesn’t store. So every time you go to race you have to set it up again. And you have to pay for most features, which is okay, I just wanna buy everything at once for like 5$ though, not all these separate purchases. Maybe a full version? Other than that it’s a great idea, just needs some modern help.

### 5/5 — Really great

*2023-05-16*

Good app, I use it with my turbo racing 1/76 and it’s perfect. App can recognize many different cars colors and you can realize many chronos at the same time. I use it when I race with 3 others friends, and the fun is here ✌️😊

**Developer response:** Hello, which iOS version are you running?

### 1/5 — iPhone 6 iOS 12.5.7 Crashs

*2023-04-22*

It is only possible to Open the App.
If i want to select something, the App Crashs

### 3/5 — Black car on slot track

*2023-02-25, version 3.4*

Can’t seem to get the app to detect a black car on the trace. Any advice?

### 5/5 — Great alternative to expensive timing systems.

*2022-08-11*

Was looking to add timing for my backyard off-road track, didn’t want to spend over a grand for friends and my kids to drive so I started looking into apps. It took a bit to get this calibrated right to recognize the cars, but once I did it’s been great.

### 4/5 — Backyard fun!

*2022-04-08, version 3.3*

Very impressed by RC Timing. I tried it out in my backyard with a course running around a set of cones and over a jump. Had my iPhone 12 Plus Max on a tripod with a battery pack (because my battery was low when I started). Even at dusk it worked well tracking my red Tamiya HotShot driving on beige grass. Didn’t even need to turn on the LED light. It occasionally missed a lap, but that was probably my camera configuration not being perfect (too big of a threshold for the target before I figured out how to adjust it). I’m just using the timer as a novelty as I’m not racing at a track, but thought it would be fun to check my times somehow. I wore my AirPods and got the times announced in my ears from across the yard! So fun to have that iconic “track voice” at home. My other buggy is a Tamiya Grasshopper which probably won’t work because it is box-art white. Will considering purchasing the upgrades but kind of wish there was an unlock-all-for-one-price option. Only real complaint is that the UI is a bit buggy and a bit unpolished. It’s functional though once you figure it out.

### 4/5 — Good but wish it had slightly more features

*2021-12-19*

I like the app so far; I haven’t done a thorough test and setting camera car colors seems to be a little hard to get right but I’m figuring it out. I’m a little confused on some of the setup but overall seems very efficient at doing what you need it to do. I have purchased all the in app purchases to help support this team.

Some features that I would love to see 

- Formula 1 style Starting Light Sequence when beginning the race 

- It would be nice if you could have Driver profiles and could then attach different cars for each event to the driver. I have a lot of friends playing and we all take turns picking different cars. So it would be nice to see driver 1 and then could add car 1 and then the next race we could switch and say driver 1 is driving car 2.. then it could keep track of the driver history and race results.
