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).

Great service

I love BookFusion. The devs are very responsive in their discord and subreddit as well.

And you can’t beat the price!

This is an amazing app for those who want to read books across different platforms and keep the highlights synced. The best part is the Obsidian plug-in, which imports all of your highlights in a neat fashion and is fully customizable. Wait, I lied. The best part is the monthly subscription price. They’ve made it extremely affordable for people to use unlike those other ridiculous apps that you see a $10 monthly subscription. At 1.99 a month it’s excellent.

Love it until...

I discovered only 10 books...back to looking for another reader.
But I have to say, it’s really very well done.
