4/5Excellent and versatile file viewer
It says hex, but you can view in binary and ASCII as well. The app is really well thought out with nice features such as: - strong search facility with REGEX -you can select different types of views with just a tap -A real bonus is all the relevant file information that is provided by the app. I would give it five stars except for a minor, but annoying, bug which I have reported to the developer. I'm running the latest version of iOS 14 and the caps lock and num lock features on the keyboard do not work with this app. Instead of staying locked, they switch back to their default positions. So if I turn on caps lock and type "b" I get a "B". But all the following Characters are lowercase, and you can see The caps lock turn off. Same thing with num lock. You get one number and then the keyboard switch is back to alpha. All in all, it is still the best file viewer I have found for iOS and it's right up there with the best file viewers I have used on windows and Linux. It does look like the developer is making regular updates, so that's great. I appreciate that he has a link to send bugs and feature requests.

4/5Great, but waiting for edit functionality
Very polished. Looks good. Works well. In fact an effectively replacement for Files app? Just wish I could actually edit files. Changing extensions names too would be great. 3.5/5 for now

5/5A life-saver
The design is thoughtful and elegant; simple, as a mobile app demands, but without skimping on powerful analysis features (although you might have to switch out of portrait mode to make the most of them)! This is by far the best hex viewing app I've ever used. The colors (and value ranges to which they apply) make finding certain patterns in files INCREDIBLY easy... to the point I always wish I had just loaded it up sooner. From a design standpoint alone, this app easily takes the cake over my PC go-to.

5/5Great Utility
This app has a lovely interface and does what it says it does and beyond. Lots of format options for viewing your files and the developer was quick and responsive (also patient and polite) to resolve the ONE and ONLY issue I have ever encountered with this app. On smaller screens, try turning the device to landscape orientation for more detail and different view

5/5Works well, beautiful design
The app is fast and responsive even with large files, the search tool is very usable and the theming is pleasant. I would like to request float and double BE/LE be added to the Decoding section of the Analysis view. Thank you!
