### 2/5 — Good enough

*2022-07-10, version 1.6*

UI is easy to read and navigate. I only have a fee grievances:

- A lot of settings (endianness, row size, radix) could probably be moved to a separate config menu.
- Tab duplicate/unpin/trash would be better as a tooltip, not a drag-and-drop.
- “Insert mode” keyboard isn’t scaled properly.

It’s pretty ridiculous that I have to pay a monthly subscription to use a simple hex editor. There are thousands of free desktop apps and websites which do the exact same thing. I don’t blame you, though.

With the whole $99/year indie dev fee, it’s only natural that the Apple doesn’t fall far from the tree.

### 1/5 — 打开二进制文件全是xxxxxx

*2026-03-25*

只会显示xxxxx

**Developer response:** 感谢您的反馈。
显示“xxxxxx”并不是错误，而是免费演示模式中超过256字节限制的内容。这个限制在应用中已有说明。
升级后可以查看完整内容。

### 1/5 — Unusable

*2026-03-25, version 1.13*

This time-waster just nags you to send money without ever demonstrating that it would be any use.

### 1/5 — Star is 0

*2026-01-14*

Hidden 0x0100~

### 1/5 — You have to pay a subscription to edit a whole file

*2025-06-25, version 1.13*

Yes you do

### 1/5 — Templates?

*2025-04-25*

Sadly, I can't evaluate if this program is capable of handling e.g. template oriented tasks, etc. for my application or if operation/handling is sufficiently easy ... 256 Bytes are not enough, sorry.

I don't see any reference to subscriptions or fees in the App-Store either.

I'd suggest implementing a trial period, e.g. a few hrs and max. e.g. 5 separate files.

As I frequently use large files over time _not_ needing to lug Laptops around with me all the time would really be nice.

I fervently disagree with the subscription model. Call me old-school (which I am).

Therefore, a lifetime or version limited license would really make me happy. E.g. this and the next version perpetually for a fixed amount.

If it's really that good, you'll certainly find enough willing to shell (reasonable) money...

**Developer response:** A lifetime licence is available as well as a monthly subscription.

### 1/5 — 收钱才能用

*2024-02-22*

中国软件收钱才能用，找到完美替代品，网站hexed.it，网页版。

**Developer response:** Это откровенная ложь. hexed.it едва ли может являться разумной альтернативой, так как представляет из себя просто игрушку с большими проблемами в удобстве использования по всем аспектам - просмотра, редактирования и сохранения изменений. Более того, эта поделка практически неадаптированна для работы на IPad/IPhone. В ней отсутствуют многие возможности, имеющиеся в PotoHEX, такие как кодирование/декодирование, шифрование/дешиврование, компрессия/декомпрессия, преобразования кодировок, работа с qr кодами и многое другое. hexed.it как и любое веб-приложение имеет принципиальные ограничения, связанные с ограниченностью функциональности работы в песочнице веб-браузера, что никогда не позволит ему сравняться по функциональности с нативным приложением таким как PotoHEX.

### 1/5 — Not enough

*2023-10-15*

Being able to see just the first 256 bytes of a file really isn‘t enough for anything, literally any web Hex Editor is better. Even though the paid version may be cheap, there‘s always people who can‘t pay. Please change that.

**Developer response:** If "literally any web Hex Editor is better" on your iPhone/iPad, use it instead of this App!  And who are the people who can afford to buy Apple's products but can't pay for App? Are you kidding? Either way, there was a lot of time and effort put into creating this app and there is no reason to devalue that by offering this App for free.

### 1/5 — Demo mode is a joke

*2023-01-22*

First 256 bytes of a File? Really?! Will not buy if there is not the possibility to do real testing of the software.

**Developer response:** The demo mode is enough to test all functionality. But if you want to try volumes 1 euro is not much. It's less than a tram child ticket. But if it's so expensive, this App is not for you.

### 2/5 — useful kinda

*2024-11-18, version 1.13*

only shows the first 250 bytes without purchase but good for pretending i know what im doing when i don’t so 2 star

### 2/5 — great, but I hate how you can only view 256 bytes if you didn’t pay

*2024-11-12, version 1.13*

:(

### 5/5 — Great

*2026-03-12, version 1.13*

Works well. Know that you can scroll vertically and horizontally in address, data, and ASCII fields. You can also resize the columns and you can also pinch and zoom to make things more readable. Powerful hex editor.

### 5/5 — Perfect

*2025-02-17*

This is by far the best hex-editor on the store. I don't understand those negative reviews because of the limited test version. This app has a small subscription fee (I personally don't like subscriptions but here it makes sense) and a fair one-time payment fee. Also this app does not spy on you. Paying 10 bucks for such a well done app shows respect to the hard work and supports a rare fair developer. Thanks Sir.

### 5/5 — Great and useful tool

*2024-12-27*

Look at the possibilities in this app, it is amazing. One time buy possible, this is very good. Thank you!

### 5/5 — Most underrated hex editor

*2024-02-07, version 1.13*

I don’t know why there’s bad reviews this is really good.

### 5/5 — Works as intended

*2023-06-13, version 1.13*

Read the title.

### 5/5 — Works very well

*2022-11-28*

Great app

**Developer response:** Thank you!

### 5/5 — ⭐️⭐️⭐️⭐️⭐️

*2022-05-15*

Круто!

**Developer response:** Thanks! This review made my day!

### 3/5 — 能适配iOS14.7吗

*2023-08-22*

我下载了该软件的13个版本(从Version1.0到Version1.13)，出乎意料的都无法安装在iOS14.7的系统上。我存在侥幸心理，结果app真的是起兼iOS15。你可能会问为什么不升级到iOS16.6，因为14.7的系统对TrollStore的支持最完美。那么问题来了，如果不留在旧系统就没有文件管理权限，没有深层文件访问权限的情况下16进制编辑器就没有用了。修改照片的不会用，会用的修改系统文件。

这真是矛盾

**Developer response:** All Apps in TrollStore are, in fact, free software. So if someone wants an App "for free" she or he should sponsor its development. I think 2 BTC is enough and I'll release my app "for free" for all significant iOS versions. See details in the GitHub repo of the App.

### 3/5 — Can’t really test without purchasing

*2023-06-12, version 1.13*

Unless you pay to unlock it, it only shows the first 256 bytes of any file. 
Pity as without being able to test it properly, it’s a Delete from me.

### 3/5 — So far so good

*2022-10-10, version 1.9*

This is to be honest the best free one. I could do what I needed to do. This is pretty good. All I would say is to make getting the file after editing easier.
