Rangefinder measure distances from the iPhone to a visible object!
Simply:
1 - hold the device upright on your knee, look at the target and then tap the screen
2 - stand up, overlap the target and the image in the middle and then tap the screen
Features:
- measurement units: meter/feet
- fine calibration
- vibration alarm
- bubble level
- measurement quality indicator
Works well in range 1-50 meters
For the better results:
- use the fine calibration for known distances
- avoid vibrations
- bring upright your iPhone using the bubble level
- use 5x zoom
=========================================
Rangefinder è un telemetro a coincidenza (distanziomentro).
Con Rangefinder diventa possibile misurare la distanza di qualunque oggetto visibile!
è sufficiente:
1) appoggiare liPhone sul ginocchio, centrare con il mirino loggetto del quale si vuole conoscere la distanza e toccare lo schermo;
2) alzarsi in piedi, centrare nuovamente loggetto con il mirino cercando di sovrapporlo allimmagine precedente e toccare lo schermo;
CARATTERISTICHE
- unità di misura: metri/piedi
- calibrazione fine
- indicatore di vibrazione
- livella a bolla
- indicazione della qualità della misura
NOTA
La bontà della misura è apprezzabile su distanze inferiori a 50 metri.
Per ottenere i migliori risultati:
- utilizzare il settaggio fine su distanze note a priori
- evitare vibrazioni durante le misurazioni
- cercare di mantenere il telefono verticale (guardando la livella)
- utilizzare lo zoom a 5X
Pros and cons of Rangefinder app for iPhone and iPad
Rangefinder app good for
If you follow the instructions, its pretty accurate. I used it in my living room to measure speaker distance while setting up 5.1 DD. Then used a measuring tape and the measurements were within a couple of inches. If you dont follow the instructions, its very inaccurate.
Ive just tried this on a few around the house projects were I needed distances and its pretty close, accurate enough for my needs (fencing length estimate, gutter height, interior ceiling heights and such). And, its dead easy to use; 2 steps and done! Thanks for making an app thats so easy and useful.
I followed the directions exactly, I even measured the distance from my knee to where I hold the phone straight out (which is 3.5 ft) and adjusted the calibration, and it was basically spot on. Tried it several times and its pretty accurate. Good price for this app! Follow directions people!
On my sailboat I am always in need of a quick range check to channel markers or land. The problem is that I have to use a chart plotter or such, or know the exact height of the remote object and have a transient to measure the angles. This tool reverses the math and I need only know the distance in height between my first and second reading.
Here is a great trick for very accurate fixes. 1) get a yard stick or something you have the exact height of. 2) set that height in the settings. 3) take care to accurately overlap the two images.
I took 14 range fixes from my iPhone on my sailboat and compared them to the very accurate chart plotter. The accuracy was amazingly close.
Perhaps the developer would consider adding azimuth and bearing in the future. :-)
Some bad moments
DO NOT BUY THIS APP!!!!!!
It is a piece of crap. This app is not accurate at all. Horrible!! A complete rip off. If I could give it no stars I would.
Repeating the steps on the same object returns vastly different results each time. Needs work.
I agree with a previous review left by another user. This thing is just guessing. If you do two identical measurements you will be given two vastly different readings!
Wholly unreliable....
This app is terrible so far from right its not funny, what a waste of money
I want my $ back. This thing is no where near to being accurate! By far the absolute worst app Ive ever purchased! Only giving a star b/c I have to.
After I followed the instructions I didnt get an accurate measurement.
