It does what you would expect. No bells. No whistles. There is an add at the lower third and sometimes it’s pornographic so NOT FOR KIDS! You use the camera and place the projector where ever you need it and the freeze the image. ### 1/5 — 不是很喜歡 *2024-10-08, version 3.5.2* 如果需要寫紙上的話，是不建議下載的 因為你要一手拿著手機一雙鞋子真的很難用 所以我這邊建議不建議下載 卸下來很難用 ### 4/5 — 最近ブル○カ始めました *2024-07-10* 競泳水着の角度を測るのには使いやすかったです。 ただ、分度器自体は細かく角度を変更は出来ず、画像自体を回して角度を測らないといけないため、少し面倒です。 ### 1/5 — Useless *2023-01-22, version 2.2.5* Hard to believe there reviewers are real. This app is worthless. ### 5/5 — 順利使用 不錯用 *2022-11-26, version 2.2.5* 就是個量角器，功能正常，沒看到廣告，好用！ ### 1/5 — ゴミアプリ *2022-11-22* カメラは常にぼやけています ### 4/5 — Really Helpful *2022-08-18* I like this app and it is really helpful for my geometry homework. It’s a big harder to use than a normal protractor but I like it 😄 ### 5/5 — Great app! *2022-07-18* It’s free and it works. Yeah, it has little ads at the bottom but that doesn’t stop its functionality. All the other reviews that whine and complain about this useful free app are just bogus! I used it to find the angles on a porch handrail so I could duplicate the cuts in the boards for my other porch rails. Thanks for the app! ### 4/5 — recommend *2022-02-02* this saved my whole grade, my only complaint is that you cannot freeze the image, my hand shakes a lot so it's a little hard but over very well ### 4/5 — Close to perfect! *2021-10-06, version 2.2.5* A very good app, could benefit from uploading a still and overlaying the protractor rather than just via camera, my shaky hands made it hard to read. ## Frequently asked questions about Protractor (Angle measurement) ### What does the Protractor app do?
