### 5/5 — Prefect

*2025-04-17, version 2.0.1*

Best drag racing app

### 1/5 — Doesn’t work

*2023-05-19, version 2.0.1*

Was a great app , doesn’t seem to work anymore . Tree drops but can’t get a reaction time on either pro or full tree . App hasn’t been updated in 7 years .

### 2/5 — Could be better

*2023-03-06, version 2.0.1*

This app is good, but the lack of customization made me go download Tree RX instead.

### 1/5 — Stage to start time is always the same

*2023-02-08, version 2.0.1*

The stage to start time is always the same.  After half a dozen tries you’ll get used to the time it takes from lighting the “staged” bulb until the tree drops.

In real life, the stage to start time isn’t always the same, and if you stage first it’s based on when your opponent lights the “staged” bulb.  

Poor representation of a real life drag racing tree.

### 1/5 — Dissatisfied

*2022-06-04, version 2.0.1*

This app is worthless. I had an app on my android that allowed me to edit settings. I race in a series that uses a .4 tree. You can’t change the tree settings or vehicle reaction time, etc. This app has none of these features.

### 3/5 — Could be better

*2021-07-10, version 2.0.1*

This app is good, but the lack of customization made me go download Pony Up instead.

### 1/5 — Tree Drops

*2021-01-16, version 2.0.1*

Tree drops way to fast. Should really get fixed. I know it’s fast because we run super pro dragster and another app that many don’t use in the App Store, we use the same delay and it’s almost perfect to what we use at the track.

### 1/5 — I only wish the lights were like this, it doesn’t test anything

*2020-10-15, version 2.0.1*

The lights are patterned. So you stage and in the exact same set amount of time, every time.... the pro tree starts. Within 2-3 attempts, you’re cutting .00X lights because you’ve figured out the pattern. Typically, there can be up to a 7 second delay after staging. 
Kind of sad, considering the name on the app.

### 1/5 — Does not work correctly

*2020-08-25, version 2.0.1*

This app is inaccurate and lights reset before you get your RT and gives false times even if you don’t react. Not a good app.

### 5/5 — It helps

*2020-07-01, version 2.0.1*

Really helped me cut a better light
