I would rate it higher if there was an easier way to delete files or to select multiple files to send or delete. The process right now is cumbersome ### 3/5 — recherche *2020-04-19* pas de recherche par un nom ou titre possible ça semble indispensable ### 3/5 — Langage en francais *2020-02-27* Choix langage please, en french.Thank you ### 5/5 — Mobile scanner that’s light enough to take everywhere *2019-09-26* Scanner works! Flawlessly. With options to export in colour, grey scale or B&W, either as an image or a pdf, it takes the hassle of trying to find a scanner when your Hi-res phone cameras can act as one and even more. Adding OCR functionality would be awesome, with extra language support, but then again I have apps for all that and can use the exports from this app to do further work. Simple. Stylistically just right, and minimalist with no room for error or having to learn a new interface, this app is often part of my arsenal when working using only my iPhone as a mobile office. Thanks for this. Given it 5 stars for the sheer ease of function that follows the easy form so well ### 5/5 — Very useful app *2019-05-08* I use it at least once a week for the last year. ### 4/5 — Edited images cannot be saved directly to the album. *2019-03-12* Edited images cannot be saved directly to the album. ### 4/5 — Great App! *2019-02-18* I have used this to scan legal documents. I scan and export as PDF and it’s worked really well for me! ### 5/5 — 相当好！ *2019-02-05* 非常完美！非常好用！ ### 4/5 — Falta optimización para iPhone XR *2019-01-29, version 2.2* Me encanta esta app pero en iPhone XR al momento de guardar en el carrete no se puede y se cierra la app, la usaba en iPhone 6s Plus y si funcionaba bien allí ### 4/5 — Buena pero necesita resolver problemas iPhone xs max *2019-01-07, version 2.2* Es muy buena aplicación, ya la usaba en iPhone 7 plus y todo bien, cuando cambie a iPhone XS MAX ya no pude reportar las imágenes al carrete de fotos, se cierra al exportar. ### 5/5 — Marvelous *2018-12-19, version 2.2* What a handy scanner I love it. Thanks a lot guys ### 5/5 — Ottima app, insuperabile nel suo genere *2018-11-02, version 2.2* Da scaricare perché è veramente eccezionale ### 5/5 — Great app *2018-11-02, version 2.2* Was a great app on my iPhone 6s . Just can’t get it to load everything I had stored ### 5/5 — Better shots of page *2018-10-22* Needs a better way to scan the page. It only gets part of the page. ### 5/5 — Very capable *2018-10-22* Downloaded this app, forgot I had it until I needed to do some scanning. My computer’s printer/scanner was too cumbersome and didn’t produce nearly the quality of this app. Very easy to use. ### 5/5 — Great *2018-10-13, version 2.2* Very handy, mostly easy to use. ## Most critical reviews (10 lowest-rated) ### 1/5 — APP SUCKS *2026-09-02, version 2.5* App sucks ### 1/5 — Good, but… *2021-12-03, version 2.2* First not easy (almost impossible) to take a good shot unless you have some sort of tablet/smartphone stand. Second, any warranty that my images remain private? Even if the wi-fi connection is disabled chances are that the app sends the pic after connection is restored. In short, thanks, but no thanks. ### 1/5 — Useless *2018-12-25* It crashes and closes everytime I try to save an image ### 1/5 — لا انصح به *2018-11-28, version 2.2* أولا : لا يأخذ مقاس الورق المراد تصويرها بدقة.. وتكون الصورة بشكل غريب لا يليق ببرنامج مدفوع. ثانيا: السعر مبالغ فيه، ولو كان مجاني لا يستحق التنزيل. هذا رايي قد نتفق او لا نتفق. ### 1/5 — Crap *2017-11-01, version 2.1* Can’t even correctly recognize the borders of white paper on a dark table. That’s just the basics for a scanning app. Thank god this app was free when I got it. Otherwise waste of money. Hell, waste of time even as a free app. ### 1/5 — ยังไม่ดี *2017-10-31, version 2.1* Cam scanner ลูกเล่นเยอะกว่า ### 1/5 — 什麼鬼 *2017-06-05, version 2.0* 掃出來的是什麼東西，看不懂 ### 1/5 — Platzverschwendung *2017-04-19, version 2.0* Kann weder OCR noch vernünftig automatisch entzerren...Das kann die interne Cam mit export nach PDF (über Drucken) selbst. verschwendeter Platz. ### 1/5 — Not good *2017-04-19, version 2.0* I tried to scan a document but the scanner can't find the edges 85% of the intents. ### 1/5 — Does not scan with the right size *2017-03-21, version 1.7* The app works great until it's time to email a document. I scanned a 10 page document to be emailed as a PDF attachment. 10 pages are scanned as a 20MB file...that's huge. 10 pages should never be that big. The email gets stuck for a long time before it's able to go through because the file is so big. The same document scanned by a "real" scanning machine comes back with a size of 3MB for the 10 pages. Something is wrong with this app and there is no settings to be able to adjust the scanning settings. Sent from my iPhone ## Most praised reviews (10 highest-rated) ### 5/5 — Definitely a 5 star app *2025-03-21* I downloaded a bunch of scanning apps for my iphone, tried them 1 by one over the course of a few weeks. I deleted them all except for this one. It does what I need it to do. WAY better than taking a photo of a document. At the moment there aren't many reviews, I'm surprised at this for a 10 year old app. They don't charge for it yet update it. What's not to love about it? ### 5/5 — Great Scanner *2024-02-07, version 2.2* Love this app! ### 5/5 — Easy To Use, time saver *2023-05-10* love this for easy and fast scans, can adjust document intensity, easy to align accuracy Have on my iphone and ipad (most used scanner) ### 5/5 — Shouldn’t have abandoned this… *2022-05-22* I love it - have for many years. Shame there is not way to backup or “select all” to export. ### 5/5 — Amazing! *2021-12-11, version 2.2* So simple to use, and it really WORKS. I couldn’t believe it! ### 5/5 — Great app! *2021-07-21* Very simple to use. I’ve been using it for years and it works great. ### 5/5 — Супер *2020-10-12* Отличное приложение, а самое главное со сменой телефона все без проблем перенеслось ### 5/5 — Improvement *2020-09-12, version 2.2* Please just put an edit ability in all scans category so we can multi check and delete scans we no longer need !!! ### 5/5 — Great App *2020-08-13, version 2.2* Been using this for quite some time now and I really love it. I’m wondering though if it’s possible to be able to delete a whole set in the gallery? Thanks ### 5/5 — Extremely useful *2019-12-05* I use this app to shoot pics of documents I need to share. And can instantly send them as a PDF or an image and send them to whomever needs it either via email or text message. I highly recommend this app for anybody we need to send documents immediately.
