## What is Ruler / Measuring Tape?

Three ways to measure when you don't have a measuring tape or a ruler:

1 – AGAINST YOUR SCREEN
Simple and precise for small measurements.

2 – IN AUGMENTED REALITY
Place a virtual measuring tape on a vertical or horizontal surface, such as a wall, table or floor. Built with ARKit.

3 – USING AIRPRINT
Print a ruler! Accuracy depends on the printer, so check the result against the on-screen ruler.

NO ADS / NO IN-APP PURCHASES / NO TRACKING

### 1/5 — Frustrating

*2026-08-01*

The idea is great, but to use it it’s so frustrating trying to work out what to do. I just deleted it in the end.

### 5/5 — The app needs work but it works for distances of 15 feet roughly

*2026-06-05*

The app works but the range of footage it can measure before losing tracking kinda sucks but it has free demo without giving away your credit card details so it’s will be worth a buy if developer fixes the range issues.

### 1/5 — Not accurate

*2026-05-12*

Not only not accurate, but also mistakes vertical with horizontal axis most of the time.

### 5/5 — DO IT

*2026-03-25*

Download this app is exactly what you want, it’s not a potato.
Bless the developer for making a high quality must have app for free without ads or tracking.

### 1/5 — It does not work

*2026-03-06*

Impossible to accurately measure anything

### 5/5 — BEST MEASURING TOOL

*2025-12-12*

HONEST REVIEW - This is the best measure tool without promotions or disturbances in between. Im really surprised to see such an awesome working tool after installing and uninstalling so many useless applications. Fantastic work from the Developer. Kudos and a big shout out to the efforts for making such an amazing product for us!! One last thing, if you tend to use this app and enjoy it do not forget to leave your experience or comments as it really encourages the developer to make something good imo. Cheers!

### 5/5 — 広告なし。目盛りのズレなし。

*2025-11-11*

・アプリ起動が早い。
・計測中に広告が邪魔しない。
・目盛りのズレがない(13miniでは)。
・アプリアイコンがダサくない(重要)。
の4点を満たせていて重宝してます。

AR計測にも即飛べるのでPro持ちはもっと便利かもしれません。
定規やAR計測の選択が初見だと混乱するかもしれませんが一度わかればすぐ使えます。

### 5/5 — Good design

*2025-10-16*

Thank you for adding support for iPhone Air!

### 1/5 — Please Update!

*2025-08-04*

Please look the screen off the ruler. I need the ruler only every day. Thank you🙏🏼

### 1/5 — Forces off the flashlight

*2025-06-01*

Don't really like that this app force turns off the flashlight

## Frequently asked questions about Ruler / Measuring Tape

### What can I measure with this app?

You can measure small objects directly on your device's screen for simple and precise measurements. For larger items or distances, you can use augmented reality to place a virtual measuring tape on surfaces like walls, tables, or floors. Additionally, the app allows you to print a ruler for physical measurements.

### How does the augmented reality measurement work?

The app utilizes ARKit to enable augmented reality measurements. You can place a virtual measuring tape onto vertical or horizontal surfaces in your environment, allowing you to measure distances in the real world through your device's camera.

### Is this app free to use?

Yes, this app is completely free to use. It does not feature any advertisements, in-app purchases, or user tracking, providing a clean and uninterrupted measurement experience.

### How accurate is the printed ruler?

The accuracy of the printed ruler depends on your printer's calibration and the printing process. It is recommended to check the printed ruler's result against the on-screen ruler provided by the app to ensure its accuracy for your needs.

### What devices is this app compatible with?

The app is built with ARKit, which typically requires devices that support ARKit for the augmented reality features. For the AirPrint functionality, you will need a compatible printer. Specific device compatibility details are usually found in the app store listing.
