On an iPhone, this isn’t an issue, but on an iPad, it makes it very difficult to use. Previously you could hold it with both hands and use a thumb for the shutter button; now you have to somehow hold it with one hand, trying to steady it, and use the other hand to tap the shutter button. This is darn near unworkable. I have communicated with them, and they have responded, promptly and politely as they always do, and they are considering this issue and are taking time to collect feedback on this issue; so, I ask and encourage you all to do just that - please communicate with them and ask them to put the shutter button back on the right side (on the iPad version) to return functionality that is essential. Once this issue is resolved and functionality returned, I will very happily change my rating to 5 star. Thank you! ### 2/5 — Annoying, pushy sub and ai features *2026-08-27, version 8.39* This app used to be an easy recommendation, but like everything else these days, the sparkles and subscription features are relentless. Disappointed. ### 5/5 — Always Does the Job *2026-08-25, version 8.38.1* I’ve been using Scanner Pro for a long time now. I’m pretty much ditched my old scanner as soon as I downloaded it. Easy to use always reliable produces great documents. I’m able to connect to my cloud drives easily for saving. It reproduces everything really well & I can save in various formats. Wish I could afford the pro version but for the moment this does everything I need. ### 5/5 — Best scanning app *2026-08-25, version 8.38.1* This scanning app has saved us so much time. Captures are crystal clear, efficient and easy to use. ### 5/5 — Easy, fast scans on the go! *2026-08-24, version 8.38.1* Been using Scanner Pro for several years now, and absolutely cannot live without it for a few reasons… one being in the type of work that I do I never know when I need to send a document quickly to another person that might be in my country might be outside of my country wherever, but Scanner Pro allows me to convert it to PDF easily and send it to wherever I need it to go including myself or in my Google Drive making document organization easier than ever for me personally ### 5/5 — Scan file, *2026-08-24, version 8.38.1* We always love our scan pro to scan the documents save it and send it to other concernnparty via e- mail etc. It is very very helpful to us. If anybody want to use a scan pro app. Welcome and good luck for your best experience. Thank you, Vinod ### 5/5 — Scanner Pro *2026-08-24, version 8.38.1* Scanner pro is seriously an amazing app, the only downfall is that I cannot delete documents. I have tried and I deleted documents I no longer need stored on the app and they are back in the line-up of docs. I have gone into the deleted app section and deleted all but they still come back to the line-up. ### 5/5 — Excellent *2026-08-24, version 8.38.1* Saves me ### 3/5 — Slow to open *2026-08-23, version 8.38.1* Recents changes make the app slow to open. Not sure why? ### 5/5 — Great App *2026-08-23, version 8.38.1* Been using for a number of years and it suits all of my purposes. ### 5/5 — Best scanning app ever! *2026-08-22, version 8.38.1* I have been using Scanner Pro for years and it is still by far the best skinning app out there! ### 5/5 — Awesome *2026-08-21, version 8.38.1* Very convenient works great ### 5/5 — Performance *2026-08-21, version 8.38.1* Product has gotten very slow over the years ### 5/5 — Can’t live without *2026-08-19, version 8.38.1* This is a simple app but when I need to scan something, I just use this instead of my rinky-dink printer. It looks so professional. I have used it personally as well as professionally. For a free app, this does a fantastic job! ### 5/5 — Amazing! *2026-08-19, version 8.38.1* I have been using this app for around 10 years and it has always been super convenient and it is packed with convenient functions. No brainer to get ## Most critical reviews (10 lowest-rated) ### 1/5 — Worthless to me *2026-08-29, version 8.39* My camera with text capture is more useful. This just puts “scanner pro” in diagonal lines all over your document. Useless. ### 1/5 — Not happy with latest update *2026-08-26, version 8.38.1* Since the last update my pages no longer scan the same size. Even though they are the same size. Which to be honest would happen occasionally prior to update. Difference now is when I then manually set them all to letter size they no longer all end up the same size. They don’t change at all from the scanned size. This is very frustrating, my scans are no longer clean and tidy. Please fix. Still waiting on a fix. When you go to edit to size the sheets you can have the option to select all types of different sizes (letter, legal, receipt, a3, a5, etc) but no matter what you select the size doesn’t change. It still remains the same size you scanned it at. I scan documents to send to customers along with their invoices. I use to be able to make it so everything was the same size & looked professional. Now it’s all different sizes and looks awful. Not sure what that last update did but it ruined everything! Developer response appreciated but still not happy, does not bring me peace of mind. I like to be able to see in the app (like we use to) that all my pages are the same size. If I can’t see it before hand I can’t trust it. Also, now I have to actually edit each page and make sure they are all set to the same size because sometimes they may look it but one might be letter another might be receipt. There is no way to set them all together to the same size so it is taking me more time to do my job. Also, once I received your response I checked a couple pdfs that I sent to myself to see if they were indeed at least the same size on that end and a couple of the documents were all skewed. So I had to go back in to the app re-edit and resend. Then they were fine. AI doesn’t always make things better, some things are better the way they were. ### 1/5 — SLOW!!! *2026-08-24, version 8.38.1* Of course you can’t contact the developer - still VERY slow to start and not functioning well. Looking for a good scanning app if anyone has a recommendation? This used to be a great app - now it take 3 to 4 minutes just to load - then it won’t scan until you “clean the lens”. Every time!!! I’m now looking for a new scanning app. This one has become exasperating!!! ### 1/5 — USED to work very well… *2026-08-22, version 8.38.1* This app used to work very well. It was my go to to scan in any documents on the go to save receipts and to easily export edit and modify the scan all within the app was amazing. Now simply trying to scan in a receipt, my phone takes the photo, the thumbnail shows up in the bottom right hand corner-but the counter stays at zero. It then freezes I am unable to see any of my older documents as I can’t leave that screen. So, anything that I’ve recently worked on or anything I’d like to do is locked up. The app completely locks up. I have to force quit, and when I reopen the application it’s the same merry-go-round. Please fix this I would hate to lose my documents, or have to find something else. ### 1/5 — Used to be Awesome *2026-08-20, version 8.38.1* This app used to be great! Simple to use, scanned docs and let you save them in the app, export as needed. Now, since I’ve had to restart my phone, I had to update to the latest version, which doesn’t let you export unless you have the $10/Week subscription! Insane! This is SO unbelievably disappointing. Will be deleting this app. ### 1/5 — Does not scan books. What a waste of money *2026-08-17, version 8.38.1* This is a garbage app. It will scan one page and that’s its. The next page the app just sits there and does nothing to capture. What do you expect from an Eastern European company. ### 1/5 — SLOW!!! *2026-08-16, version 8.38.1* This used to be a great app - now it take 3 to 4 minutes just to load - then it won’t scan until you “clean the lens”. Every time!!! I’m now looking for a new scanning app. This one has become exasperating!!! ### 1/5 — Sketchy auto-renew *2026-08-15, version 8.38.1* Charging you ever 7 days is predatory. I have forgotten about the app and I’m out $$$. This app is sketchy. ### 1/5 — Pro but full of ads *2026-08-11, version 8.38.1* This is a pro version of Scanner, but they don’t allow you to use the app unless you watch long ads of subscribing to their Plus plan and pay monthly rental. Not sure how Apple allows such developers. ### 1/5 — Crashing *2026-08-05, version 8.38* I’ve updated the app, restarted my phone and the app crashes at 140 pages scanned every time. ## Most praised reviews (10 highest-rated) ### 5/5 — Perfect App *2026-08-28, version 8.39* Still one of the best apps I use. It is priceless for me. Can’t imagine not having it. Previous review: Love this App. Been using it for about 10 years now and they are continuously upgrading Makes my life easy. What a great app for personal and business purposes. Highly recommend it. ### 5/5 — Terrific! *2026-08-28, version 8.39* I’m not so happy with the same garbage that every application does. Stopping me from using the program to sell me up. Leave me alone I love the scan program , the camera on my phone ### 5/5 — Pictures *2026-08-28, version 8.39* Great ### 5/5 — So easy to use *2026-08-27, version 8.39* It is so nice to have an app that converts docs to PDF with a photo function. Need need for scanner hardware anymore. ### 5/5 — Convenient *2026-08-27, version 8.39* Love this app. It saves time ### 5/5 — An Amazing, Reliable App! *2026-08-27, version 8.39* Scanner Pro has *never* let me down. It has consistently produced sharp, accurate images for me for many years now. It just keeps getting better. I even had the assistant at my doctor’s office make a comment to me about the images of both sides of my health insurance card that I uploaded to their patient portal. She said, “Wow. That’s probably the some of the clearest pictures of their insurance card anyone has ever sent to me.” I said, “I used an app on my phone called Scanner Pro to do it. It makes everything super-sharp and clear. You should try it. It’s awesome!” So, just know that Scanner Pro is so good that you have longtime customers out here spreading the gospel for you! Thank you to the entire team at Readdle for such a useful, reliable, easy-to-use, wonderful app. The improvements over the years have only made it better. Keep up the great work! ### 5/5 — Good *2026-08-27, version 8.38.1* Ok ### 5/5 — Great Scanner! *2026-08-26, version 8.38.1* Once you get the features, this is a wonderful scanner and the new AI detection they’ve added works fall asleep for me. ### 5/5 — Maritza *2026-08-26, version 8.38.1* Muy buena y profesional ### 5/5 — Great app *2026-08-26, version 8.38.1* Great app easy to use, dependable and free. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
