There does not appear to be any way to calibrate and correct the error. ### 3/5 — .. *2026-02-24* Wish the ruler zoom out:/ ### 3/5 — I can’t move the ruler *2026-02-15* Would be better if I could measure things longer than 4 inches and I only got the app because I have no idea how to read a ruler ### 3/5 — ads mask basic functionality *2025-09-08, version 1.19* got this for the ruler. the ads banner covers the fractional numerical display of measurement ### 4/5 — Not accurate. *2025-08-05* My ipad is 11 inches and the ruler on the screen is only 9 inches…. What? ### 5/5 — Great App! *2025-06-28, version 1.19* Easy to use and accurate. Just what I was looking for in a measuring app. ### 5/5 — Love it! *2025-06-16* Seriously handy for small measurements ### 5/5 — マジで便利 *2025-04-23* 低温調理の際に、にくのあつみを測る時に使ってます！ ### 3/5 — Not accurate on iPad Pro (12.9 inch display) *2025-04-02* Downloaded this app to use on my iPad for a crocheted project that needed a base size of 8 inches. 500+ stitches later (about 12 hours extra work) and I double checked measurements with a physical tape measure, come to find out I had an extra 2.5 inches added to the base. Remeasured on the app to see if it was user error - nope. I checked on my iPhone and the app measures perfectly there — I think on the iPad instead of getting a longer ruler the app just blows the image of the ruler wider. Please be careful if using this app on anything other than an iPhone! ### 4/5 — 惜しい *2025-02-13* 勝手に横画面になるのと、アイコンがダークモードに対応していないということ以外は良い 他の画面定規アプリと比べてデザインが良いのでこの2点ぜひ改善して欲しい ## Most critical reviews (10 lowest-rated) ### 1/5 — Minimizing, useless *2026-06-15* Keeps minimizing when u put something on top so you press and hold, WHY??? ### 1/5 — Measurement Privacy Problem *2026-02-04* I was measuring in the bathroom stall at work as you do, but for some reason, the app uses a text to speech to say the number you measure aloud, so while people are waiting for the one and only stall, the app says "2.74 INCHES" at 100% volume. I cannot recommend this app. ### 1/5 — Can’t see the numbers do to the ads *2025-12-21* I can’t move the ads which are covering the numbers so if the voice was turned off I wouldn’t get results at all ### 1/5 — It’s wrong *2025-12-16* The ruler is the wrong size. It’s about 25% wrong on my iPhone 15 pro. That’s way too far off to be acceptable ### 1/5 — アプリで1cmが実際には1.3cm *2025-08-29* iPhone16eの場合、タイトル通りの差があり使えない。設定で機種に合わせた補正機能が必要。 ### 1/5 — Not working *2025-03-31* Tried on iphone 12 max pro and the marking is definitely not adjusted and too large. ### 1/5 — 正確ではありません *2025-02-08* iPhone15Pro Maxですが1cmがちょっと大きく無い？と思って実際の定規と比べるとこちらのアプリの方が2mm程長かったです パーツの大きさを確かめたかったので2mmの誤差は大きすぎて私の用途では使えませんでした シンプルでいい感じと思ったのに残念です ### 1/5 — Not accurate *2024-11-24* 아이폰 15pro max 에서 15cm 와 아이패드 air m2 11 에서 같은 앱으로 15cm 비교하면 약 2cm 의 오차가 남. ㅋㅋㅋ 장난치고 있나? ㅠㅠ 이런 앱이 어떻게 애플 앱스토어에서 통과되었을까? ### 1/5 — 실제 자와 수치가 다릅니다. *2024-07-10* 유료 결제했더니 실제 자와 달라요 충격 ### 1/5 — 広告削除300円とられた！ *2024-04-14* 広告削除と出てきたからポンと押したらすぐ課金画面になり一瞬で300円取られた。 購入しますか？みたいな確認画面が欲しかった。やられたー！ ## Most praised reviews (10 highest-rated) ### 5/5 — Actually Surprisingly GREAT! *2026-08-02* This is what apps used to be and should be. It does a lot of good useful functions quite easily. There are unobtrusive adds and it has never begged me or tricked me into paying. Most measurements apps are complete scams and virtually useless. Well done! Do you make other apps? ### 5/5 — Great App!! Love simplicity ! Easy to use also informative. *2026-07-10* Easy to use and accurate. Just what I was looking for in a measuring app. ### 5/5 — สะดวก *2026-04-13, version 1.21* ใช้งานหด้ดี เส้นคมจุดอริ่มต้นควรให้เห็นชัดตั้งแต่ 1 มม เพรทะใช่ ไอโฟน ### 5/5 — 便利 *2026-04-01* 出先や身近に計るものがない時に使用してます。 ### 5/5 — Nice *2026-03-01* It works well ### 5/5 — Not having a ruler *2026-02-06* I have to do my homework and I use this app very helpful ### 5/5 — 👏👏👏 *2026-01-22* 굿👍 ### 5/5 — Great! *2026-01-02* Fantastic, useful, and accurate! My one suggestion would be to have the ability to be able to move the ruler down a bit so you can see the zero line. ### 5/5 — This is the one! *2026-01-02* Get this one! It is simple and reliable for small measurements! ### 5/5 — Great, absolutely useful! *2025-11-23, version 1.21* Thank you so much for this app, it is the only app I have found which makes exactly what it promises! I have some ideas for improvement, but it is still worth of all the 5 stars! My ideas which could help making this app even better: • This „Dynamic Island“ on the newer iPhones overlap a little bit with the symbols on the right side. • It would be great if there is a possibility to disable the touch function automatically if I use the slider for marking of a distance. (if i want to put something directly on the ruler, it messes up the measurement) • You could make an extra button which creates a faint line with an incrementing number. (Maybe even a number which the user could write a comment to and can save it to an overview site for an project) • It would be cool if a user can organise the symbols for the different measurement systems and the setting-symbol to his own liking (maybe an option for the premium user, so that the symbols don’t interfere with the ad?) • maybe an option in the settings to hide the switches for imperial-vs-metric and one-marker-vs-two-marker within the settings (for user who like the minimal style) • an option to chose the color for the highlight on the ruler with a slider (i already love the possibility as it is!) • the possibility to automatically calculate the area or volume of 2 or 3 measurements ——————————— All this points for improvement still doesn’t change that this is a great app!
