AR rangefinder · iPhone
Range anything you can see, with just your iPhone
Point your iPhone at a disc-golf basket, a disc, a tree, or any other target you can see, and Cliptracer Range tells you the distance, elevation change, and grade. No walking there, no extra hardware.
Made for disc golf: read the hole from the tee, or measure how far your throw landed. No rangefinder to buy, charge, or remember to pack. Your iPhone is already in your pocket. One-time $9.99, with no subscription, no ads, and no account.
How it works
Parallax triangulation: the same principle as your two eyes judging depth, or a surveyor sighting a point from two spots.
Sight the target
Aim the crosshair at the target and tap Add Sighting. You fine-tune the aim on a frozen frame, so placement is pixel-precise.
Move, sight again
Take about 10 steps to the side, or walk toward the target, and add another sighting of the same spot. Either way works; each sighting is a line of sight from where you stand, and the more you move, the tighter the result.
Read the result
Where the lines cross in 3D is your target: distance, elevation, and grade appear instantly, with the converging sight-lines drawn in AR. Add more sightings to shrink the error, shown live as a ±.
See it in action
Why it's accurate
Simple, robust geometry
Your iPhone precisely tracks how far you move between observation spots, and the measurement comes straight from that baseline and your aim. Nothing to calibrate, nothing to guess.
The more you move between sightings, whether a wider step or walking toward the target, the tighter the result. It stays precise at the shorter distances where a GPS reading tends to be loose.
Two ways to measure, both accurate. Step to the side and sight twice for a quick reading, or set your spot and walk it in. The walk-in gives a result that's just as tight, often tighter, with no sideways angle to line up.
Requires an ARKit-capable iPhone.
Why not just GPS, or a laser rangefinder?
vs GPS apps
- No walking to the target. A GPS measurement means walking the full distance to drop a pin. Here you measure long distances from where you stand.
- Tighter accuracy out to a few hundred feet, which is where most disc golf shots live.
- Short distances work too. GPS error swamps a 40 ft measurement. This reads it cleanly.
vs dedicated rangefinders
- $9.99 once instead of a hundred-dollar gadget.
- Always in your pocket. Nothing to charge, pack, or dig out of the bag, so it's the rangefinder you'll actually use.
- Elevation and grade included with every measurement.
What you get
Any target, even out of sight
A basket, a disc, a tree, a person across a field. Pinch-zoom locks onto small, far targets. And you don't even need to see the target from where you measure: mark your spot, walk until a disc that landed behind a tree comes into view, sight it, and get the distance from your mark.
Distance, elevation, grade
All three at once, in feet or meters, so you read the whole hole, not just the line on the ground.
A number you can trust
The live ± shows exactly how tight the measurement is, and every sighting you add shrinks it.
Private by design
Everything runs on-device. The camera is only used for the live AR view. No photos, video, or location ever leave your phone. $9.99 once, with no subscription, no ads, and no account.
