### 1/5 — Billing  without permission

*2026-07-24, version 4.2*

This app bill automatically if you forget to cancel after seven day free trial. I don’t even have the app on my phone after the first five seconds of downloading the app to see how it worked and they charge weekly. this is an unethical way to do business.

### 3/5 — Doesn’t work offline

*2026-07-24, version 4.2*

Works well when on WiFi or with cell service but doesn’t seem to work without internet service which is half the time I need it.

### 1/5 — Your phone is the angle tool...

*2026-07-09, version 4.2*

The camera feature requires subscription.

### 5/5 — User

*2026-05-24, version 4.0.1*

Works Great

### 1/5 — Freezes and add

*2026-05-20, version 4.0.1*

Had not used app in a while. And now it is extremely slow to start. Has adds and a overpriced subscription. I deleted it and will double check that developer is not trying to charge a subscription fee regardless. Very disappointed

### 1/5 — No longer free

*2026-05-14, version 4.0.1*

Was free to use until I opened today, now it isn’t.  I sell angle finders for a fiver in work and can have one for free. Guess what’s in my toolbox from tonight 👍🏻

### 1/5 — Стало платным

*2026-05-04*

Пользовался приложением для заточки ножей. 
Отмерял сколько градусов от заданной точки , а сейчас это платно??? Вы че там совсем офигели? За что платить деньги? Удалил приложение

**Developer response:** We appreciate you taking the time to share your feedback. 
        If there's anything we can help with, please feel free to contact us at ruler.measure.info@gmail.com.

### 1/5 — Not a “free trial”

*2026-05-04, version 4.0.1*

I downloaded this app to give a try. Signed up for the free trial and the moment I hit accept I was charged $21.00. I saw no mention of a charge  except for the annual cost which was to be paid at the end of the trial period. I cancelled the subscription and deleted the app but the charge remained on my account. It’s been more than two weeks since then. 
The app itself seemed to work well, but not for that price. Especially an annual fee.

### 1/5 — Siren’s Song of Avarice

*2026-05-02, version 4.0.1*

Like many others, I bought this app a fews years back (single purchase, no subscription). Unfortunately, it appears social conformity affected the developer a while back and they now feel a sense of entitlement to your wallet from now until the funds dry up. Nice try… but I have access to real tools and this is a minor convenience I can do without. “Restoring” a previous purchase is buggy and the app hangs making you think it’s broken. To boot! The next time you launch the app it will have no memory of a restored purchase and solicit you with the subscription screen only to repeat the same maddening process - Every. Single Time. “If it ain’t broke, fix it until it is.” (iPhone 14 Pro, Build 4.1.2)

### 1/5 — Me

*2026-03-29, version 4.0.1*

I BOUGHT This app 5 years ago, no you want me to buy a subscription on top of that?
