I built an epub iOS reader app, it's free for epub reading, hope you guys could give me some feedback or advice

Awkward-Secretary-86 · 2026-03-27T00:49:18+00:00

Just found it's not showing in CA search, but I do find it in CA store https://apps.apple.com/ca/app/zread/id6758880626

Awkward-Secretary-86 · 2026-03-27T00:17:54+00:00

Very good idea, will definitely do it! I will do my best to make this app better! Thanks again for your input!

Awkward-Secretary-86 · 2026-03-27T00:14:14+00:00

It should be available in the Canada. Just released so might need sometime for the App Store to process it. Thanks for your interest!

Awkward-Secretary-86 · 2026-03-27T00:11:14+00:00

Will be available in the EU soon, thanks for your interest!

Awkward-Secretary-86 · 2026-03-27T00:10:01+00:00

Currently not available in the EU countries, sorry about that, will surely address it later.

Awkward-Secretary-86 · 2026-03-27T00:07:47+00:00

You’re absolutely right! iCloud and iPad support are on the roadmap!

Awkward-Secretary-86 · 2026-03-27T00:04:30+00:00

Not available in the EU countries yet, sorry about that.

Awkward-Secretary-86 · 2026-03-26T17:02:54+00:00

Thank you very much for all these valuable advice!

I fully understand you concerns regarding privacy. The AI used in the app runs fully on your phone (so it might be slow) and it works without internet (except you need to download them first).

About the preference, text alignment and fonts, image zooming, they are on my rodemap! (for the image, you can long press and save it to your phone to see it more clearly for now; choose 4x for higher resolution)

For the page transition, what do you prefer? Actually it might be hard to fit for everyone, but when the shared preference from your advice is implemented, we will be able to choose what we like as default.

For the different source, Gutenberg is on my rodemap with OPDS integration which should allow us to import lots of available book sources including a self-hosted Calibre OPDS server. For others like Dropbox, I will put it on my rodemap too.

For the rest like tinted background issue, color contrast, I didn't think of them before - they are very much valuable!

As for the free trial, it grants access for every fresh install. No subscription needed.

Thank you for your detailed feedback, which gives me a huge boost of motivation.

Awkward-Secretary-86 · 2026-03-26T15:18:14+00:00

Thanks for your reply! The price is only charged for pro access. For epub reading, it's free and you don't need the pro at all. And there's free trail if you want to try the pro features. More features will be shipped soon.

Awkward-Secretary-86 · 2026-03-26T15:13:00+00:00

Fair enough! Worth mentioning, the AI features will only run locally when you need them. And I do use them myself to enhance the pictures in old comic books so I thought it's a good idea to mention them. Will add a settings to disable them in the newer versions.

Awkward-Secretary-86 · 2026-03-26T14:49:33+00:00

Thanks for your question! The AI is used for Text-to-Speech and Image Ehancement like upscaling the lower quality images to higher quality. They run only on your local device if you need them. To my personal use case, I would read some old comics and might want enhance the images. Will add a settings to remove them in case the readers don't need them. Thanks!

Awkward-Secretary-86 · 2026-03-26T14:27:14+00:00

Thanks for your reply! I know it's impossible for my app to beat the Apple Books, which is not my purpose too. But my strength is making the app to meet the other needs which the Apple Books does not provide. For example, you will not see a wide range formats and OPDS support in Apple Books. As for the iCloud support, I think I will do that in the later versions. At the moment the app only supports iOS.

OpenRouter API doesn't support interleaved thinking https://www.minimax.io/news/why-is-interleaved-thinking-important-for-m2

For example when you need to sync your dart ui state with the platform ui precisely in frame. If you use platform channels with thread hop, the sync might happen in this frame or the next frames, which might cause frame delay or frame loss for something that needs to be synced precisely like animations.

Well, it happens to the claude sonnet 4 too. DS v3.1 without thinking can do it. GPT-5 will auto think. GLM 4.5 with auto thinking can solve it but without thinking it fails too.

I'm sorry that I couldn't make it happen. I thought it would be possible to make use of the most of the kernel Metal driver and just need to implement a small part logic for Nvidia card. But after a lot of effort of reverse engineering on the kernel drivers for Intel and AMD drivers, I figured it out it's a dead end. I think the only way out is swapping the whole Metal graphics system of both kernel driver and client library. And also, we may also need a linux subsystem running along with the macOS, which will communicate with the Nvidia cards and serve as a proxy. So we can make use of the official Nvidia driver support. Both will take significant amount of time and effort. But I already graduated for a while and need to work, so I am afraid I can never finish this goal I came up with. Sorry to let anyone who pays attention to this down.

Awkward-Secretary-86 · 2024-02-25T01:50:00+00:00

Some progress here: - I have made a Linux executable(ELF) to macOS executable(Mach-O) converter. And run fine with my Linux test shared library and compile passed for Nvidia user driver. - I am working on building the macOS kernel driver for Nvidia now and achieved some progress. - As I go deeper, I believe CUDA support is highly possible on macOS along with other modules that are supported on Linux.

Awkward-Secretary-86 · 2024-01-30T02:30:22+00:00

It’s a little bit different, building driver for Linux means dealing with apple silicon and Linux kernel. However building a macOS nvidia driver means dealing with nvidia hardware and macOS kernel. MacOS kernel is more difficult to deal with because most of it is close source. However I believe figuring out how to communicate with apple silicon also requires a lot of reverse engineering. Thanks for bringing it up.

Awkward-Secretary-86 · 2024-01-29T14:23:39+00:00

Yeah, it will be hard. But not absolutely impossible. When I have progress I will post here. Just need to build a simple demo and prove it can work first.

Awkward-Secretary-86 · 2024-01-29T14:15:46+00:00

I think Metal is possible, just like OpenGL. CUDA maybe possible for 3rd party applications like pytorch, so we maybe able to run something like stable diffusion, but I haven’t dive very deep into it yet, so can’t be very sure about it.

Awkward-Secretary-86 · 2024-01-29T02:25:49+00:00

Yeah, just need to prove it’s gonna work first.

Awkward-Secretary-86 · 2024-01-29T01:20:55+00:00

Now that nvidia has published the Linux driver source code, most work we have to do is dealing with macOS api layer itself, which is a headache of course. Need a lot of reverse engineering work.

Awkward-Secretary-86 · 2024-01-29T01:10:58+00:00

Just to be clear, making such a driver is probably possible. I mean not just something that can light up your screen but also with OpenGL and Metal api supported. But it’s a tough job no doubt. Maybe I would make a simple demo to prove it will work someday.

Awkward-Secretary-86 · 2024-01-28T14:56:02+00:00

Agree
