MiXplorer (Mix) : Clean and powerful file manager at the same time. It’s easy to use for normal user and very powerful for power users.
Lookup Pro: Floating dictionary that can blend in to native Android context menu when highlighting words. It’s similar to iOS lookup or Kindle lookup feature.
Maosure: Google virtual measure app that make use of ARCore library.
Moon+ Reader Pro: favorite ebook reader
Seal: Favorite youtube downloader. Unlike other YT downloader that is riddled with Ads, it FOSS app.
Toolwiz Photos: Best all in one photo editor for me. It’s very underrated. The variety of feature it pack is u match by any photo editing apps for me. From color correction to healing and cloning tools, the fun feature that gets old very fast like face rater, face swap, pip, etc. I just noticed that it has AI painting feature too.
TTS Server : Azure/Ms Edge TTS ported to Android to use it as system wide TTS. It’s the most natural free TTS I’ve ever used. It’s originally Chinese only app, but I forgot where I got English version from.
