World's Lightest Launch Monitor

Know Your Real Distances

Your iPhone measures ball speed, launch angle, and carry distance. No hardware required.

3 warm-up shots to calibrate. Then every shot is measured automatically.

No spam. Just one email on launch day.

Launch monitors are incredible tools. They start at $200 and the best ones cost $20,000. Most golfers have never been able to justify one for their practice sessions.

So you practice without data. You hit a bucket of balls and walk away wondering if it helped. You don't know your real carry distances. You're guessing, and you know it.

Practice With Purpose

You walk onto the first tee knowing your 7-iron carries 152 yards because you measured it 47 times last month. Your practice sessions aren't guesswork anymore. They're data. You see your consistency improving. You find the gaps between your clubs. You stop wondering if the range is helping and start seeing that it is.

Built by a golfer in Eugene, Oregon who wanted the same data the pros have, without the $600 price tag.

A golf ball is 42.67mm. That's been true since 1990. Your iPhone captures 240 frames every second. From those two facts, speed becomes knowable.

Built in a garage. Being validated against professional systems.

Acuvis started with an iPhone on a takeout container and an orange foam ball that no launch monitor could detect. Built in the margins of 50-hour restaurant weeks by a solo founder with AI as a development partner. Four complete engineering approaches. Three killed, one shipped. Five months from idea to validated measurements.
