### 1/5 — Deceptive pricing.

*2026-07-30, version 2.2.16*

They will charge you 50 dollars per month.

### 1/5 — Predatory subscription

*2026-03-20, version 2.2.10*

Signed up for a 3 day trial and was charged $14.99. Beware, this app attempts to scam you out of your money.

Update: misleading response from the developer. I was charged immediately upon signing up for the trial, before the three day trial had expired. Don’t waste your money with these scam artists.

### 1/5 — Scammy practices

*2026-02-20, version 2.2.9*

£13 a week for a ruler app? That’s just shocking

### 1/5 — Predatory subscription

*2025-12-06, version 2.2.7*

Signed up for a 3 day trial and was charged $14.99. Beware, this app attempts to scam you out of your money.

### 1/5 — Abonnement

*2025-10-13*

Abo für DeutschlandCard, Amazon Prime, Office365, Adobe Phothoshop, Chat GPT, Smarthome (zb Tado), Spotify, Ziffernblätter Smartwatch - wer möchte ernsthaft etliche Abonnements abschliessen für insgesamt hunderte von Euros? Wenn ihr meint im Markt der ganzen unsäglichen Softwareabonnements, weil die Monetarisierung von Diensten wiederkehrende Einahmen verspricht, mit einem weiteren Abonnement zu bestehen …

**Developer response:** Hallo! Wir verstehen absolut, dass die Vielzahl an Abonnements heutzutage frustrierend sein kann.
Allerdings bietet AR Ruler eine ziemlich einzigartige Funktionalität: Mit Hilfe innovativer AR-Technologie können Sie Maße direkt über Ihr Smartphone erfassen. In vielen Situationen hat die App klare Vorteile gegenüber einem klassischen Maßband - zum Beispiel bei schwer erreichbaren oder unzugänglichen Objekten.
Wir arbeiten kontinuierlich daran, die App weiter zu verbessern und ihren Nutzen zu erhöhen. Vor diesem Hintergrund halten wir den Preis für die Premium-Version für fair - insbesondere für Nutzer, die diese speziellen Funktionen regelmäßig benötigen.

### 1/5 — 正直な気持ち

*2025-07-26, version 2.2.3*

使えないとかのレベルじゃないです。
まともに測れないのにスマホは熱を持って熱くなるだけで、定規を測ってもズレているのでこのアプリは使わない方がスマホにとってもいいと思います。

### 1/5 — Such a simple app require you subscription

*2025-07-26, version 2.2.3*

Took more than a minute with dozens popups on initial launch. Then the ruler does not even work. They require me to download an additional tools like ???? Im warning yalll this app is not worth it for such a simple task. I wouldnt even be writing this if ONLY I have my measuring tape!

### 1/5 — Completely not worth it- all features offered are free on an all that comes pre-downloaded on iPhone

*2025-05-14*

Nothing pisses me off more than the fact I never signed up for an annual plan for this app and yet still got charged $90. There’s nothing this app offers to even pay a single dollar for. Literally everything they offer comes with a free app for iPhone. I think about this constantly I basically just donated $90 to a scam. Don’t even download this app there’s no purpose to it when you can get their services for free.

**Developer response:** Hello! Thank you for your feedback. We're truly sorry to hear about your experience. We always aim to provide a helpful and transparent service, especially when it comes to subscriptions.

We also recommend checking your Apple ID subscription settings, as sometimes subscriptions can activate through free trial periods. We’d also appreciate hearing more about what you felt was missing in the app so we can continue to improve.

Thank you again for sharing your thoughts - we value every piece of feedback and always try to respond.

### 1/5 — Scammed out of $20

*2025-03-31*

Be careful when you install this app. As I unfortunately found out if you accidentally touch the screen at the wrong time you get signed up for a subscription whether you want it or not.

**Developer response:** Thank you for sharing your experience. We're truly sorry to hear that the subscription process was not as clear or convenient as expected. Our goal is to ensure a smooth and transparent experience for all users, and your feedback is invaluable in helping us improve. If you could provide more details about when and how the issue occurred, we would greatly appreciate it. Please feel free to reach out to our support team, and we will do our best to assist you!

### 5/5 — Great App to obtain home (windows and such) measurements!

*2024-12-16*

Takes a bit to learn how to navigate. A little patience and I figured it out! Definitely recommend for windows and other areas of a home that are not easily accessible. Not sure that the cost of an annual membership is necessary for personal use though.

**Developer response:** Hello! Thanks for the feedback and we are delighted to know that you've chosen our app to make measurements.We try to improve AR Ruler in order to serve you well. Have a wonderful day!
