Perfeito

Testei (juro) mais de 10 APPS similares e este é o melhor que eu encontrei. Têm inúmeras configurações, para agradar a todos. Opções de tipos de rolagem de tela, margem, visual limpo na leitura. Simplesmente perfeito.

Needs attention

Needs attention on the ai reading out loud
The ai stops at certain pages. All the time. And you have to skip 2 pages at a time to pick up the reading.
So it takes your attention off what you’re doing. Driving or working machinery.
Needs look at asap
I paid for it to. But the potential is huge for the company 🌞❤️🌱🏴󠁧󠁢󠁳󠁣󠁴󠁿🙏

The best Cross Plattform reader including PDFs with sync of read position!

I was looking a long time for a cross platform (iOS and Android) reader especially for PDFs. I prefer reading on my Boox e-paper reader which is android based but also want the option to open the same book or PDF on my iPhone or iPad. This does that perfectly. In case of questions the support is reactive with real solutions (not just the AI support circle of doom). I played around a bit with the TTS function. It is quite good but I prefer real audio books read by professional speakers. But if you like that kind of function it is well implemented and works surprisingly well.
I have been using book fusion now for over three years and couldn’t be happier.
Pricing is very reasonable and has not been increased while I was using the service. So another plus.

Heating issue

The app is great, but the tts makes my iPhone heat up like crazy. I hope that future updates will solve this problem.

Response from developer

Hey BarracudaFickle, You are using the free Local TTS voices. Local TTS voices download the model directly to your phone and processes generating the audio for your book on your phone. Local models will work best for mostly the higher end devices. We suggest you use the Advanced voices that are streamed to your device with realistic and high quality(requires the Advanced plan and above). Alternatively you can use the TTS voices provided by Apple which are not ideal in quality but will also not result in your device getting hot.

Best reading app

I’ve been using this app for years on my devices. It has every QoL features I need, such as auto scrolling, tts at ridiculous speeds and ridiculous horizontal margins (which I use for reading faster on my ipad without having to move my eyes across the screen).

It also has some new TTS voices that work locally and sound amazing.

My only gripe is I need to import my files inside BookFusion instead of keeping them in a folder, such as iCloud or Obsidian. But, no other app has done this well yet (some such as Documents allow this, but the reader is awful and crashes on large books).
