★★★★ LadyWhitnye 6/16/2026 v4.24.36
You must enter the app to use it
When I share photos they go no where. I must go into the app and pull photos from there. Waste of time really.

★★★★ Okkiiyygfff 5/22/2026 v4.24.35
Серьезно?
Мне нужно заплатить за то, чтобы отправить файл? Почему я об этом узнаю только тогда, когда уже сделал фото всех документов?
Конченое приложение
★★★★ Black cat 4264 4/13/2026 v4.24.35

★★★★ MnAmom 2/16/2026 v4.24.34
Worst app
I usually don’t have issues figuring out how to use an app but this one just sucks! I was trying to print a 5 page doc and all the app would do is “prepare it for pdf print”. I tapped print and nothing.
It also doesn’t allow you to delete your “account”. I signed up, unwillingly, for a 7 day trial and I want to delete all of it. I don’t want my Apple account charged for anything but I can’t find where to cancel the free trial - I don’t want to be bothered with canceling it a week from now - as well as cancel anything associated with my information.
★★★★ Lost all documents 1/23/2026 v4.24.34
Lost everything
Do not see a way to recoup any of the scans I had on my previous phone, there is no login for Scan Hero that I can see
★★★★ TiffinOz 1/4/2026 v4.24.34
Deleting
Used to be able to capture a single page and email it to myself without a subscription but now this app requires a paid plan for that. Removing this worthless app.
★★★★ Scammedbydev 10/27/2025 v4.24.30
scammers
charged my family with weekly subscription 7.99 when a month or yearly subscription is not much more than that. When apps uninstall themselves from your phone it does not update you. Why resort to predatory practices on consumers? Because they are scammers.
★★★★ windbite 10/19/2025 v4.24.30
Watermarks, ads and $10/mo
Save time and money, don’t download this
★★★★ Vroomer25 8/9/2025 v4.24.26
Costs $100 to not use it for a few months
I stopped using it after the free trial and had plans to use it in the future, I only just realized it has been charging me $8 a WEEK. A WEEK. Ridiculous price! Not using it for a few months costs me nearly $100.
It also had trouble scanning ANY document that is stapled; if the corner is folded when you’re on literally any other page than the front page, good luck getting a good scan.
Waste of money. Thanks a lot.
★★★★ Taboladesignes 8/7/2025 v4.24.26
The support doesn’t pay attention
Support is not responding to any request, the scanner stopped working.it’s not transferring documents from email to scanner.
★★★★ jahgfv 7/7/2025 v4.24.25
One star
Used to be great then they did some kind of upgrade where they put the date in the subject line and you can’t tap on your photo and go automatically to scan Hero. There’s also no place from the app to get in touch with Support.
★★★★ Joflaherty95 7/2/2025 v4.24.25
Terrible app
Once you sign up, they won’t let you cancel. The free trial isn’t worth it. And they will charge you every week and make it difficult for you to get your money back.
★★★★★ alex94cc 3/11/2026 v4.24.34
to many times rate required
The app sometimes will close by itself in the middle of making a file with scanning documents
Some of the function on the app doesn’t work
