On iPhone 7 with latest software update. I work in a metals distribution warehouse and have to carry a 60’ tape measure with me constantly to tell the difference in-between 55’ and 60’ beams. When the app did work it was always at least 3’ to 6’ off, even after a perfect surface detection over a span of 50 to 60’. Up close it seems to work ok, but is off a good 1 to 2” sometimes. I still use it to get a general sense of sq footage when figuring steel plate for processing work comparing what I have on hand to work with, but practical accuracy is not there with really any VR app I have used yet, not just this one. ### 2/5 — Ne marche pas avec iOS 12.0.1 *2018-10-16* Après la mise à jour vers iOS 12.0.1, l’application ne s’ouvre plus. J’en ai besoin pour mes activités, je souhaite vivement que cela soi corrigé dans les plus brefs délai. Merci **Developer response:** Le problème a été corrigé dans 1.54. Veuillez mettre à jour l'application et réessayer. Merci d'avoir signalé le problème. ### 1/5 — 起動できない。 *2018-10-13* ios12.1で起動したら、クラッシュしてホーム画面に戻ってしまう。 **Developer response:** この問題は1.54で修正されています。 アプリを更新してもう一度お試しください。 問題を報告していただきありがとうございます。 ### 1/5 — Crashes on start *2018-10-13, version 1.48* Looks like an app I could use with our kitchen remodel. Paid for the app based on reviews. Downloaded app onto my iPhone 7 Plus and it displays a splash screen then crashes to my home screen. Reset phone, deleted and reloaded app from store ... no luck. Disappointed. ### 1/5 — ダメです。 *2018-10-12* 新しいOSでは、開くことができません。 **Developer response:** この問題はすでに1.54で修正されています。 アプリを更新して再試行してください。 問題を報告していただきありがとうございます ### 1/5 — 為什麼下載不能用？ *2018-10-12* 點進去就閃退？剛購買就不能用？手機是iPhone 8 plus 系統iso12.0.1，求解？求解？求解？ **Developer response:** 問題已在1.54中修復。 請更新應用，然後重試。 謝謝你報告這個問題 ### 1/5 — 動きません *2018-10-11* iPhone X/ios 11.4.1で使用するために 購入しましたが、起動後何も表示されず。真っ黒な画面の非表示になったタスクが残されるだけです。 こんなソフトを販売するのは、勘弁して欲しい。 **Developer response:** 最初の起動には以前よりも時間がかかりますので、数秒間黒い画面が表示されることがあります。回避策として、デバイスを数秒間動かずにしっかりと保持してください。すぐにシーンが表示されます。私たちは現在この問題に取り組んでいます。 報告いただきありがとうございます。 ### 4/5 — やっぱり計測よりこっちの方が◯ *2018-09-18* iOS12の計測アプリはシンプルで良いが、こちらの方が便利。 ただすぐiPhone端末が熱くなるのが難点。 ### 1/5 — Inadequate instructions *2018-09-15, version 1.45* The app is not intuitive. I watched videos on Facebook but they don’t instruct on how to do the neat things that they are showing. Until they do, I don’t recommend it. ### 1/5 — Ne fonctionne pas *2018-08-25* Quand je sélectionne la forme rectangle pour mesurer l appli arrive à mesurer la première longueur que je copie et colle dans notes Puis retour à l appli pour faire la deuxième mesure en partant du dernier point enregistré Impossible de prendre une référence cela bug J ai acheté cette appli je suis déçu **Developer response:** Nous vous recommandons de faire toutes les mesures avant de quitter l'application. Vous pouvez créer autant de mesures que vous le souhaitez, puis enregistrer la scène. Vous pouvez référencer toutes les scènes enregistrées ultérieurement à tout moment. Ou vous pouvez exporter une scène au format PDF. ### 1/5 — 10 euros pour rien *2018-08-06* En temps que pro, on me l’a vivement recommander, me ventant les avantages de cette app! Après 10 balles de paiement, voici une application d’une inutilité saisissante. Ne reconnaît ni les surfaces, ni les murs, se trompe d’échelle, et doit être redémarré à chaque calcule ou mesure. 1h de travail perdu à l’utiliser, et 10euros. Sa fait chère l’application que je m’en vais de se pas me faire rembourser par Apple. Merci pour la perte de temps. Un architecte. **Developer response:** La première et la plus importante étape consiste à trouver un mur ou un sol correctement. La précision dépend principalement de cette étape. Dirigez l'appareil photo vers le sol ou le mur et attendez un moment ou déplacez lentement l'appareil photo. Quand un plan de grille blanc apparaît sur l'écran, assurez-vous qu'il est d'environ 50 cm ou 20 pouces. Si la taille ne correspond pas, essayez de déplacer la caméra lentement jusqu'à ce qu'un nouveau plan soit reconnu. Si vous avez de la difficulté à trouver un plancher / mur, essayez de vous rapprocher du sol ou du mur. Si un bon plan virtuel est trouvé, l'erreur de mesure devrait être inférieure à 1%. Une fois que vous connaissez cette étape, cela ne prendra que quelques secondes.

Trying to get my money back. ### 1/5 — Not good *2018-06-19, version 1.43* Got the app to measure square footage on driveways. Does not measure accurately and is extremely confusing to use. Just tried to measure pool length and width... no where close to accurate. Want my money back. ### 1/5 — 100% useless *2018-05-31, version 1.41* Not accurate... not user friendly... of course no one will see my comment because they disabled comments.... SCAM SCAM SCAM... I want my money back !! ### 1/5 — No good *2018-05-30, version 1.41* So disappointed not at all what I expected ### 1/5 — Don’t waste your money *2018-05-30, version 1.41* Does not recognize any planes to measure. Useless app. ### 1/5 — Initial impressions *2018-05-27, version 1.41* I purchased this to see if my furniture would fit in a new house. Maybe I’m missing something. In trying to measure the rooms in 3D everything overlapped and looked nothing like a room at all. The room isn’t an exact box, when I moved around looking at the room on my screen it didn’t look like a dimension that humans could survive in. Useless for my purpose. As a human. The only use I see for this is maybe measuring a straight line, although I haven’t checked the accuracy on that yet. Possibly my room was too dark. It seemed to have trouble recognizing a vertical plane. Maybe due to pictures on walls? This is only my initial impression. Pure fury. Then as I stood there yelling at my phone, a message popped up asking if I loved measure 3D!! Lol. Good comedy timing I have to say!! Possibly under absolute precise lighting conditions and planetary alignment this app may be great. I’ll persevere. Any tips would be welcome. Or a refund (in human currency. Not Zeta Reticulan) ## Most critical reviews (10 lowest-rated) ### 1/5 — Fonctionne pas très bien *2023-02-17* Fonctionne très mal ne donne absolument pas les bonnes dimensions ### 1/5 — Not good *2020-12-12, version 1.63* I can’t say anything good about this app. Purchased his morning ,tried it out for an hour and the app was not responsive on the iPad. ### 1/5 — Disappointed *2020-08-28, version 1.63* Locked up my IPad Pro ### 1/5 — Doesn’t work. *2019-07-27, version 1.63* Literally just downloaded the app. Went threw tutorial tried to measure and it said “sorry”. “World tracking failed”. “Try resetting or just quit the app”. Haha. JUNK. don’t waste your time. I want my money back. ### 1/5 — Glitches prone *2019-06-11* When I click a photo and save it. In the collection section there is just a white screen that appears, though the measurements are shown but their is no photo. Just a white screen. ### 1/5 — Great idea not workable *2018-12-27, version 1.61* I am an old style computer user, and a modern programmer that writes manuals. I viewed your tutorials. Thanks for taking the time and effort to do this. I tried measuring a door in our house many times. Never worked. I I cannot measure under good situation like that, not going to be useful. Much faster to get a tape measure, or in other cases use some geometry to calculate the measurements. ### 1/5 — 直ぐ固まる *2018-10-24* 起動して直ぐ固まり反応しなくなる。 iPhone8 11.3 ### 1/5 — I can’t open application *2018-10-17, version 1.48* Application is not working, as many times I try to open , application shuts me down I tried couple times to reinstall it and it’s not working ### 1/5 — App closes immediately. *2018-10-17, version 1.48* This app won't open. Unusable for me. ### 1/5 — Can’t even open the app *2018-10-15, version 1.48* It worked for a while but now it won’t even launch. I’ve tried re downloading but nothing changed. ## Most praised reviews (10 highest-rated) ### 5/5 — 환불해주세요 *2018-09-17* 잘못 결제했습니다.. **Developer response:** 환불은 애플에 직접 요청하셔야 합니다. 저희 앱 개발사는 그런 권한이 없는 점 양해해 주시기 바랍니다. 기타 다른 문의사항이 있으시면 앱 안에서 직접 질문하실 수도 있습니다. 설정>피드백 및 질문 감사합니다 ### 5/5 — 怎么玩， *2018-07-12* 是不是要苹果差才可以玩？ ### 5/5 — Very useful once you get the hang of it. *2018-07-01, version 1.45* Little bit difficult to first get to hang of using. But once you do, wow! Really cool app. Very useful. ### 5/5 — Good journal for my kids height *2017-10-25, version 1.22* I figured out how to measure exactly in about 10 minutes. But once you know how to measure, this is very good app with many useful tools. My favorite is person height tool which I am using to keep track of my sons’ height. ### 5/5 — 感觉好牛逼的样子 *2017-10-23* 就是不知道精准度怎么样 ### 5/5 — Nothing to complain *2017-10-22, version 1.21* My experience with this AR application is completely satisfied. It helped me to save a lot of valuable time for measuring in real life and sometimes, that thing is really difficult ### 5/5 — Worth every cent *2017-10-22, version 1.21* You can't find any apps with similar pro features like Measure 3D Pro out there. So I think its cost is acceptable. Cheaper than other apps too ### 5/5 — Too many pro features inside! *2017-10-22, version 1.21* Tiny size app but it has a lot of useful features for measuring purposes . Very helpful for anyone who loves measuring or simply works as a constructor ### 5/5 — It's cool *2017-10-22, version 1.21* A brilliant idea comes from talented developers. Measure 3D Pro is a great app for measuring anything you want to check . It also has so many pro features that other free apps don't have ,so it really worth your money ### 5/5 — Finally it's here *2017-10-22, version 1.21* Yup, that's the truth when I'm looking for an application to measure anything I found but not only its height or its width but also more infomation deeper. Fortunately , it's just 3 dollars . Thanks god! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
