Protractor
Protractor works right at finding the right angle.
TOO LAGGY!!!!!
DID NOT WORK AT ALL
Fee to block ads required
Urgently needing a protractor app, I was forced to buy the pro version of this app to block ads. It's absurd to charge a fee just to remove ads to other apps from the same developer.

Good stuff
Really good stuff
Do not recommend
My screen is sideways so it must be the the camera but only in this app please help me find a better app so my homework is possible when I try fixing it it goes the wrong way help
Transportador
Buena herramienta
Only measures in “Rad” with free version
Measuring in “degrees” is only offered in the Pro version
Asks for a rating as soon as you open the app
Why would you ask for a rating as soon as you open the app? Also doesn’t have labels only picture icons. I don’t know how to use it. Deleted

Awesome tool
Buy to see degrees? 😆
Don't waste your time and money. They want you to pay in order to see degrees. Garbage money grab. Booo!
Ottima, qualcosa da migliorare
Ottima app, specialmente per la realtà aumentata. Manca possibilità di scegliere direzione con iPhone in verticale, automaticamente direzionato a destra. Per valutare gli angoli a sinistra è necessario mettere sottosopra iphone. Utile sarebbe anche introdurre opzione screen-shot e calcolo angolo automatico.
Used to work well
Up until recent update this used to measure in degrees but now only measures in radians, which you can convert online but makes it take longer to use. Not sure why you’d take the main feature away (degrees) since you can convert it yourself anyway. I understand paying for photo mode but simply showing degrees.... lost me as a user.
Very restricted functionality
Downloaded and tried to use. Operates for a few seconds then times out. Quickly removed this app
No ads
🤪🤪🤪🤪
Only Radians available
If you want degrees, you must buy the app.

Pas mal du-tout !

Though basic it can be handy. It's that sensitive it's almost impossible to hit your target on the scale using your finger. Developer needs to incorporate the volume buttons so once you have it close to your target on the scale, you could then use the volume buttons to put it on your target on the scale. Il expect an update soon otherwise it just becomes another unused app.
It’s a great app
In terms of a free useable app with minimalistic advertising it’s great, the angle meter and its base features are outstanding. I jerry rig my phone on the end of a mandrel in the spindle of my lathe and use the degree finder as a dividing device. Perfect 👌🏻 Thanks!
Can’t use existing photos.
I paid the 99 cent fee to unlock the camera. Then I found out I wasted my money as you can only use the camera within the app to measure an angle, but not on an existing photo. Too bad.
👌🏽

Highly recommend for retirees.
This is an excellent-I repeat excellent, app for addressing and meeting the needs of amateurs trying to learn and hone the skills. As a retiree I recommend this highly. Dr. J. Bassett.
Garbage
Garbage app
Molto comodo
Bella app, pratica e semplice
THIS APP IS WONDERFUL
I love this app because it really helped me when I went camping with my kids and family
DISAPPOINTED.
This app , this app right just so many ads and viruses, and if your going to make this app at least make it so you can use a camera. i TRIED to use it for work and yea, didn’t work not one bit. Do better.
This sigma
I rizzed Ohio Hyatt sigma alpha male
Not useful
If you try to use degree for measuring the app will force you to buy premium version and you can only use rad measure 😕😕😕😕
Excellent
Excellent
DO NOT USE I can’t cancel service
I have tried to discontinue my service but the app won’t stop charging me.
Top tool
Works like it says. Good app
This App is Garbage 🗑️🚮
Total trash, don’t waste your time downloading it. You won’t be able to even use it unless you upgrade… This app will frustrate you more than it solves anything
