Great app! ### 5/5 — 使いやすい^_^My favorite one! Ganbatte. *2023-03-17* 毎日毎日何度となく使っています。pdf.変換して他のアプリで使いやすい。良いアプリです。 ### 5/5 — Staple Application *2023-02-23* Use this App a lot. To package pictures and scans together. Then deliver in a PDF to cloud storage or share with others. Also, used the FAX function. Excellent App. ### 4/5 — 便利です *2022-12-08* ファイルをPDFに吐き出して、 そのまま写真に変換して送れたりします。 ### 5/5 — Reliable Scanner *2022-11-16, version 5.5* We use this scanner app for multiple medical records. The fax application is very useful too. The imaging is quite clear even at times when the ambient light is low. Downloading manuals, webpages, et cetera are a breeze. It’s a good tool to have in your mobile office’s arsenal. However, it should have a user’s guide highlighting each of its features. Yet, you’ll learn the more you use it the easier it gets. SLW ### 5/5 — Brilliant App *2022-10-20, version 5.4* Love this app so much Would be happy even more if it has the option to send messages too Thanks 🙏 ### 5/5 — Great Scanning App *2020-11-10* I love this app it works great. It’s very easy to use. And the quality of scans are awesome. ### 5/5 — Best as you could wish for. Easy intuitive and crisp results. Un Yally Mann you cats. *2019-09-10* I am no way going to use anything else. Neither should you if you want a good experience with your documents -Whatever! Today. ### 4/5 — It is so close to being perfect!. *2019-06-29* This app has improved noticeably over the years with better edge detection and smoothing out curved pages when scanning. It also seems to upload faster to iCloud and other cloud services in and across devices. This is still my go-to scanning app. In fact, I’ve deleted my other scanning apps,; which included scanner pro, Adobe PDF reader and even Lens PDF. It also has some nice extras... which I guess are the norm now for a lot of PDF scanning app or PDF readers. It does let me sign a document, it lets me write on it freely and put posted notes on it. It lets me merge or split PDF files, which is always great. It lets me email, fax (with a minimal fee), airdrop, you name it. But I think it needs a facelift and minor improvements. It still doesn’t always let me open encrypted PDF documents It detects Apple Pencil but writing with it in this app doesn’t feel as precises as in other apps. I know this is probably not the designed use for this app but i like filling out forms in it. It is clunky with adding text. I wish it had field detection so that I can easily fill out documents and submit them ASAP. It still doesn’t support split view on iPad. I wish I can have this app opened on one side and my web browser. It is still a great app to own but be mindful that if you plan to use it for editing forms it will annoy you. Also, sometimes it’ll duplicate a document just because you changed the name of a scanned file from 09_12_2019 to paper1. ### 5/5 — 好方便 *2019-05-12, version 2.9* 好方便處理資料 ### 4/5 — Unverzichtbares Scan-Werkzeug mit guter Seitenentzerrung *2018-11-26* Nutze die Anwendung seit Jahren, davor die App FasterScan aus vom gleichen Anbieter. Die App bietet eine sehr gute Seitenerkennung – auch bei extremen Perpektiven, sowie die Möglichkeit diese manuell zu verbessern. Meiner Kenntnis nach ist diese App die einzige die auch gewölbte Seiten erkennen und entzerren kann! Optional lassen sich Seiten im Farbumfang in zwei Stufen (erhöhter Farbkontrast oder Schwarzweiß) reduzieren, was die Lesbarkeit deutlich verbessert. Ich habe mehr als 12 dieser Scanner-Anwendung aus dem AppStore getestet, aber Docr Pro bietet einfach die besten Optionen. Meiner Meinung nach unterbewertet und zu unrecht bei den üblichen Vergleichslisten nicht berücksichtigt. Gute Anbindung an diverse Cloud-Speicher und -Dienste. Export wahlweise als JPEG und PDF. Faxen ist ebenfalls direkt aus der App (In-App-Kauf) möglich. Eine wirkliche Erleichterung für die seltenen Momente wenn dies benötigt wird. Ich habe lediglich zwei Verbesserungsvorschläge: 1. Bei der Farbumwandlung werden nicht immer alle Bereiche optimal aufbereitet. Hier wäre ein Pipetten- oder Auswahlwerkzeug sehr hilfreich; ebenso ein Kontrast- und Helligkeitsregler (wie bei FasterScan). 2. Leider gibt es keine Möglichkeit in die Erkennung der Seitenwölbung manuell einzugreifen. Auch hier wäre ein Anfasser wie bei FasterScan wünschenswert. Insgesamt aber eine hilfreiche und stabil funktionierende Anwendung! ### 4/5 — Music Aggregator *2018-06-25* I use Docr Scanner to copy music to a software package called OnSong. Functional and keeps all my sheet music in one place. Many times staff lines fill in with a shadow or wavy lines appear. On these occassions I need to trash and then repeat copying process. I like that it turns my music into a pdf. ## Most critical reviews (10 lowest-rated) ### 1/5 — Annoying *2025-11-29* Every time I open the app I get a message asking if I will rate the app. ANNOYING! ### 1/5 — A frustrating decline *2025-07-12* I'm writing this review out of sheer frustration and disappointment with Doc OCR Pro. For a long time, this app was an indispensable tool for me, reliably converting images of documents into editable text with impressive accuracy. However, over the last three updates, Doc OCR Pro has become virtually unusable. The core functionality of the app – the OCR itself – has completely broken down. Instead of processing documents, the app now consistently fails, It's frustrating to open the app with a task in mind, only to be met with constant failures. This isn't just a minor glitch; it's a fundamental breakdown of the app's primary purpose. It's clear that something went wrong in recent updates, rendering a previously excellent application into a useless one. I've tried basic troubleshooting steps like restarting my device and checking for updates, but nothing has resolved the issue. The decline is particularly disheartening because Doc OCR Pro used to be a standout in its category. Its ability to handle challenging scans and produce high-quality text was a significant advantage. Now, it's just a placeholder on my device, taking up space without delivering any value. To the developers (IFUNPLAY CO., LTD.): Please investigate these recent updates urgently. Your app has lost its core functionality, and it's alienating loyal users. We need a stable version that performs as reliably as it once did. Without a fix, Doc OCR Pro is unfortunately no longer a viable solution for document scanning and OCR. ### 1/5 — The best OCR on iPhones I could find (Destroyed in version 5) *2023-02-13* This is the best Document OCR app I found by luck. It is about 95% accurate with good photo. It can do things that others cannot, like make the lines continuous thus preserving paragraphs. It can pull good recognition out of if even bad photos. It can also preserve columns and do not mix up the lines in between the columns. It can even recognize some handwritten text at some level depending on the clarity of the writing. It really saved me a lot of time. I do not use anything else. It is an excellent company with great talent. It is sometimes hard to find in the App Store. Above 5 star review I have written was on Doc OCR Pro Version 4.6. When I saw it has been updated since to version 5.7 I thought it must have been improved to near perfection. I wanted update it and also install iOS 16. I thought I should see how good it is on my iPhone 14 Pro. When I tried the new version 5.7 I was shocked. The same scan with 5.7 was totally unusable. How can a company take wonderful OCR software and instead of improving it to more perfection absolutely destroy it. I sincerely recommend this company to thrash the OCR engine in the new version and go back to the OCR engine in the 4.6 version. Until then I would not recommend Doc OCR Pro for use in OCR jobs. Unfortunately, I have to keep the version 4.6 in iOS 14 on my iPhone SE to be able use this amazing OCR software. I am concerned if I update the system to iOS 15 or iOS 16 it may stop working. There is nothing better out there. If this company just take the version 4.6 and adapt it to iOS 16 and issue as an OCR software it would be wonderful. ### 1/5 — 全然補正されない *2020-10-25* 本をスキャンしようと思い購入。 全然適正に補正されません。 歪み補正を目当てに購入を検討している方はやめた方がいいです。 ### 1/5 — 本の膨らみ歪み補正が全く、完全に役に立たない *2020-09-29* 本の膨らみの歪み補正をしてくれると聞いて試してみましたが、全く役に立ちません。 膨らみのある方向を正しく判定してくれないと役に立たないのはわかってもらえると思いますが、その方向を100%完全に、見事なくらい完璧に「間違って」くれます。 そのため、膨らみを補正するどころか逆に歪みを倍増する方向の変換しかできず、全く役に立ちません。 600円は勉強量でした。 絶対に払うべきでないことを忠告いたします。 ### 1/5 — Kein OCR *2017-01-06* Obwohl der Name der App das impliziert gibt es keinen OCR. Sehr enttäuschend. App ist das Geld dann nicht wert. ### 1/5 — PDF maker? *2016-11-30* I was hoping there would be some rudimentary form of OCR but no, just a app that uses your camera to string together photos. What a gyp. ### 2/5 — Doesn’t do a good job of uncurling a page. *2019-12-04* I purchased because the video shows great uncurling of scanned pages in a book but found that the green guide line does nothing to affect the final result. Nor are you able to edit the curve of the green lines. Kinda of a waste of money imho. ### 3/5 — Not so good recently. *2022-08-24* I have been using this app since 2018 with no problems until recently. In the past 3 months I’ve had to uninstall and reinstall it 4 times because it will not open. After reinstalling, it will work for a few days or weeks and then won’t open again. I have the latest updates on the app and the phone, an Apple iPhone 13 pro max. I will be looking for an alternative app if this problem continues. Update 9/24/22: still crashing, no word from developer or any fixes for this problem. ### 3/5 — Stürzt die ganze Zeit ab *2020-02-16* Leider immer wieder beim Scannen, super Erkennung und Technik aber so nicht nutzbar.... ## Most praised reviews (10 highest-rated) ### 5/5 — Einwandfrei *2026-06-30* Für mich die beste App, um Dokumente zu scannen und als pdf abzulegen. Synchronisation mit iCloud funktioniert wunderbar (zb. scannen mit iPhone, lesen danach bei Gelegenheit am iPad). Auch Export nach Pdf klappt prima. Selbst verzerrte Scans sind kein Problem und können gerade gerichtet werden. Toll,wäre einzig noch eine Möglichkeit der einfachen Bildbearbeitung nach dem Scan (Anpassung von Helligkeit, Kontrast). Und das Beste: kein Abo und trotzdem immer wieder Updates und Verbesserungen❣️ ### 5/5 — Incredible app *2025-10-19* This has been an incredible app for pdf storage and note taking! ### 5/5 — 好软件 *2025-09-04* 非常好的软件，没有广告🪧。 ### 5/5 — 5 *2025-03-05* Отличная программа, часто пользуюсь. ### 5/5 — Very handy app *2024-12-07* This app is a lifesaver for writers and researchers documenting large quotes from books. The page uncurl feature works terrifically. Text recognition is good, but there’s always a little editing to do. Otherwise it’s great for copying a whole page at a time. Faster than Xerox, plus you get OCR thrown in. There’s a few things that could be better, but I’ve been using it for… Many years. ### 5/5 — Very handy app *2024-07-28* This app is a lifesaver for writers and researchers documenting large quotes from books.
