Honnêtement le seul point noir de l’application(et c’est un gros point noir malheureusement)c’est qu’on peut pas sélectionner plusieurs fichier en même temps ou tout sélectionner notamment pour supprimer des roman, mettre plusieurs roman de la même série ou auteur dans une catégorie spécifique etc car pour moi qui a une grosse bibliothèque de novel c’est super chiant je doit tout faire un par un. Je viens de voir le site web+ 1 étoile en espérant que ça vienne sur l’application aussi. **Developer response:** Merci d’utiliser BookFusion et pour vos aimables commentaires !

Thanks guys for the great work. Great value for the money. Keep up the good work guys. ### 5/5 — Perfeito *2026-08-05* 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. ### 2/5 — Needs attention *2026-08-02* 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 🌞❤️🌱🏴󠁧󠁢󠁳󠁣󠁴󠁿🙏 **Developer response:** Hi Tomtom81974, It would be better for you to reach out to us at support@bookfusion.com to resolve this issue with your particular case. There might be an issue with that particular book/file that we need to investigate and resolve. Please reach out to us so that we can further assist ### 5/5 — The best Cross Plattform reader including PDFs with sync of read position! *2026-07-19* 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. ### 4/5 — Heating issue *2026-06-29* The app is great, but the tts makes my iPhone heat up like crazy. I hope that future updates will solve this problem. **Developer response:** 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. ### 5/5 — Best reading app *2026-06-07* 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). ### 5/5 — Great service *2026-05-05, version 1.42.5* I love BookFusion. The devs are very responsive in their discord and subreddit as well. ### 5/5 — And you can’t beat the price! *2026-04-20* 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. ### 4/5 — Love it until... *2026-03-14, version 1.41.8* I discovered only 10 books...back to looking for another reader. But I have to say, it’s really very well done. ## Frequently asked questions about BookFusion ### What is BookFusion?
