HiDev我们需要编辑功能

不能编辑也不能批量选择、也不能搜索跳转。其实并不是需要媲美桌面端、那样太难了、但这是基本需求。想象一下都已经打开十六进制文件了(这个「场景」下)难道只是为了看一眼乱码吗。

Unusable

Constantly crashes despite repeated phone restarts and app delete / reinstall.

Most crashy app I’ve used in a long time. Junk.

sehr genial

Genau das, was ich gesucht habe. Ich bin nämlich gerade dabei, ein paar komplexe Passwörter (wiedernachvollziehbar) auf einem Blatt Papier zu notieren. Hehe.

A 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.

Response from developer

Thank you so much for the great feedback, you made my week!

App does not do what it says

I was under the impression that the app could actually edit the files, but you can only see the files which is useless for me if you wanna edit files, do not buy this app and they do not offer refunds as well which I don’t think is right because I just bought it about half an hour ago

Response from developer

I am sorry to hear that. Unfortunately it is not possible for apps in the AppStore to provide their own refunds. You can however refund the app through Apple; just google “AppStore refund”, you will find a guide that I hope will be helpful to you. I tried to make it as clear as possible in the AppStore description that the apps is not an editor, but just a viewer. I am sorry you feel misled here. I hope a refund can set things right. I would greatly appreciate if you could change your app rating afterwards; many people are actually just looking for Hex viewers and I don’t want them to get scared away from this. Once again I am truly sorry the app did not meet your expectations and I hope the refund process restores things for you.
