Built by a competitive bowler, for competitive bowlers.
Revv draws every shot over the oil, logs your tournaments frame by frame, and keeps each change beside what it did.
Every shot, drawn over the oil.
Revv follows the ball from the foul line to the pins, then draws it on the lane with the oil pattern underneath.
Speed, laydown, arrows, breakpoint and launch angle, each throw on a page of its own.
Add the pattern's sheet and your line is drawn on top of it. Switch it off above to compare.
- Phone behind the approach
- Bowl
- Every shot, on the lane
Real throws, tracked by Revv on 3 Nov 2026.
Fifty throws in one picture: the middle half shaded, your typical path drawn through it.
Change one thing, throw again, and see exactly what moved.
Set it up behind the approach and every shot is drawn as it's thrown.
Every number and the oil overlay, for anyone who bowls.
Too many steps between the lane and the answer.
How training and tournaments worked before Revv, and what each step became.
Your decisions, while the lanes still change.
Tournaments and simulations, frame by frame. Collect your thoughts between shots, commit, and see later what each decision did.
A strike is one tap.
Tap the pins left standing. Revv works out the count, whether you hit the pocket, and whether it's a split, for your bowling hand. Try it.
The leaves, not just the score.
Each frame keeps its rack: what went down, what you left, and what you picked up.
Between frames, all taps.
Your ball, line, rotation, speed, the lanes and how it felt, in a few taps. Each note sits between the frame before and the frame after, so it reads as a decision and its result.

Tag a ball in a quick note and the note lands on that ball's page. A block's summary points at the exact notes it's about.
