An extremely useful app. I had the free version for a very long time and was so impressed, I got the pro version and have had it for a few years. Def recommend the app. Not sure about the latest android update backup issues if phone is reset, but a quick backup to a memory device/ computer is a go around.

I don't understand these positive 5 * reviews here. The app is not good. The calibration of the texts and logos, e.g. for letters, is bad (this has nothing to do with the smartphone camera, because it works perfectly with other Scan apps). I prefer to pay more and get much better quality. I canceled the purchase after 30 minutes of testing and immediately received my refund from Google.

I used the free one for a while and found that I used it so much I don't mind throwing money toward the developer for the work put into this. I would like to see the ability to add sub directories at some point but in the mean time I export and place my files in other directories outside this app.

Worth every penny! I had this for years and there's not other app in the store that works as perfectly as this scanner. I can literally scan all my ID cards, Insurance cards, imp documents and share, store (within the app). It's so reliable, easy to use. I love being organized and this app helps me with that so much. I can't say enough good things about it!

As a professional trucker this is an invaluable tool, for things like making copies of shipping documents after hours when offices are closed. Scanning signed bill of lading, then eFax or email them to your home office. It works extremely well for scanning weight tickets when delivering cattle to feedlots, because many of the weight tickets copies are yellow or pink. A regular cellphone camera cannot bring out the faded ink stamp. This app allows you to scan in black & white mode & then darken!!

I am impressed with the capability of this app in producing clear legible copies without a hassle at all. I have been able to achieve things I never thought possible. Like taking a picture sent from another phone camera via WhatsApp and finally shared with Fast Scanner to produce an amazing document.

PLEASE HELP! I bought the pro version because of the auto upload to google drive. It has worked well running a small business. Documents scanned in the field could be pulled up in the office seamlessly. However, the auto upload has not worked for the last three months, and now it is no different than the free version. Edit: Auto upload has been fixed. Thank you for your responsiveness. Revised rating from 2 stars to 5 stars. Love this app!

Great app, but I had to knock off one star because they made me pay twice for the Pro version. I bought a few years ago and was very happy until my cloud sync stopped working. I found out that I needed to buy the pro version again even though my current version clearly showed I was a Pro user already. I wrote to the publisher but got no response. It's not about the money - I just don't think it's a good way to treat your customers.

One of the best mobile phone scanner apps I've seen in years. Believe me I've looked all thru the play store too. The free version is exactly same but doesn't offer file saved folders in the way that this one does. That makes it real handy to be able to move and remove scanned folder groups.

Almost Perfect. I tried a lot of image JPG to pdf apps to find what I needed. This let's you use a file manager to import files not just the Gallery There's just a one off fee if wanted & you can add multiple files, or camera scan. You can save locally and export. If the saved PDF file is removed from the app it can not open pdfs from other locations which I would like. Also OCR works well but can not be used to make PDF's searchable. Maybe these 2 things could be done in the future. Great app.

Great App For Scanning - Lacking Storage Location Option. I've been using the pro version for years. Problem is years of pdfs and jpgs fill up my phone storage. It would be a 5 star program if I could choose my sd card [samsung android] to keep all the files. The export feature is useless to me as I back up by phone drive weekly with backup software and not interested in deleting files. The program itself has an excellent post processing and easy feature to email scans to myself.

this was good. I haven't used in a while just used it. its useless i can just take a photo with camera and at least with the camera im able to crop the image. there is no editing feature in the app. dont waste your time with this app your better off just using the camera in your phone you will get a better result

Hey devs, this last update is a disaster.. My folders, sortings and files are messed up. I had hundreds of files in the FastScanner dir. I was used to access those files through other filebrowsers too. Where are they now? Dirs ended up empty.. Sporadically the app launch ends in endless wheel turning. Such a bad thing to a once great app I used to work with so long..

This is not desirable. I've bought the pro version considering some work this month. After scanning a 72 page document, I'm unable to convert it into pdf. I can not even share the pages through any of the sharing apps. In each try, FastScanner pro is crashing. Even I've tried to copy the images through data cable into my computer. Explorer is not showing anything scanned. I've shared the event log to the developers but they didn't bother to fix it. I think this app is a waste of money and time.

Having used this for a long time, I eventually went Pro as I felt the developers deserve the money :) I can now export in JPEG as well as PDF. A really useful app. Using it to preserve and share family photo albums. Good quality results, but you need to set up a simple stand for continuity of settings during a long 'shoot'. I used an open cardboard box on its side with a hole for the phone's camera cut into the topside, then the open side facing the (indirect) light. Worked a treat.

It works great, like a real scanner. Worth the $. Lol ppl complaining about ads and clouds they can't use, keep it simple! For a few bucks? Go and buy a real scanner machine if you need it to do that much even thought this app is as good! Ads are necessary to keep it going... It is just a one time pay and it's worth it! ... STOP COMPLAINING!

Excellent app that I use to capture scans of all sorts of paperwork or objects. OCR capability is very useful, able to convert picture of printed words to editable text. Handy being able to convert documents into PDF format to save/share . What would be nice is being able to add comments or notes to individual pages, not currently possible. A workaround is using the signature to add text, but that alters the document permanently, which may be an issue.

Fast scanner is an app used to scan items. Documents and then send them electronically where they need to go at the time. Also saves the docs. You can do a single doc or multiple. My only issue is that I bought fast scanner pro so I could scan and send multiple docs in 1 enail, but needed to repurchase when my phone broke and needed a new phone. Had to spend again. That is just wrong and the reason for not giving 5 stars.

CLUTCH!!! The output is better than that from an actual scanning machine. I greatly appreciate the options for adjusting the image (several BW, a couple color) since I can scan anything I can take a picture of to pdf or jpg (maybe more, but those are my main uses). It's easy to save multiple images to one document, edit file name (the default file name makes sense), save to gallery, files, or send. It's awesome, and it's dependable usability makes me much more efficient. 2018 update: still MVP.
