Two Point Height
For greater precision you should fill in the height at which you hold the device and your distance from the object.
Other height-measuring apps may require you to enter the distance to the object ahead of time, or to tap first on the base of the object and then the tip, which makes them not work well for all applications (e.g., stomp rocket flight height measurement). Two Point Height lets you select the two points in either order, and to enter the distance afterwards for greater precision.
You can also sight along the side of the phone, which is useful on sunny days as well as for viewing rockets and other small things that are hard to see in the sky.

Metric only, confusing interface, no help.
Useless...app itself is asking you distance ?💔smh
Everything is 3.76 ft!
Im assuming the increments are in Imperial or else the numers given make no sense. Multiple tests of object 12 inches in height 13 inches away give results ~.15 different from tape measure results. App results are relatively consistent. Degrees of tilt on sighting screen is a great idea. Lacks a unit of measure. Inches must be in 10ths requiring out of app calculator.
I get it about the units but I cannot guess distance to an object. I also cannot guess what my phone height is nor can i fathom it or any phone is 1.8 of any known unit. That really confuses me why that number would be default. Update: No, lack of units is debilitating to calculate phone height in same unit and be at all accurate requires multiple decimal points. That's why we have units. And i cannot possibly know distance to object or I'd just measure the object!
I have tried several height/distance measuring apps and this is the only one I have found that is anywhere near accurate. I like the fact that the app will allow you to take sighting positions first and provide an estimate of distance, with the option to enter a measured distance later. Too many apps require you to enter this distance first - not much use if you are trying to estimate the height of something half a mile away. I obtained fairly consistent results within 5% of the measured distance on a 78 inch high door at 30 feet. I like that no units are specified, you just enter a number which can be feet, metres, yards, chains, as long as all the units are the same the answer will be correct. I would like there to be some audible confirmation that you have tapped the screen to mark a point, otherwise I like it.
≥4.5 to 5s if have measurement choice ie: metric - MM, CM, DM, Meter, KM / IN, FT, YD, Mile. Also a little more in way of instructions would help. Tested again optical-transit w/steel-tape; works well for roughing & estimates, only. Did not expect precise readings ie from a transit & tape. Have tried many other like apps. TPH is as good as any, better than most & easy to use. Def a Keeper!! Mic Pete * Cl;-)~ * Ririe, Idaho USA
Makes no sense need instructions.
Not the most innovated app. Needs a better ui.
Saved the Science Fair Project My kid wanted to test the efficacy of different fins on bottle rockets. We ordered an altimeter but they sent the wrong one. We tested several different apps but this one gave the most consistent results. Highly recommended!
