Prefect

Best drag racing app

Doesn’t work

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 .

Could be better

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

Stage to start time is always the same

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 β€œstaged” 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 β€œstaged” bulb.

Poor representation of a real life drag racing tree.

Dissatisfied

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.
