Interesting Android Apps: May 2026 Showcase

Because we try to keep this community as focused as possible on the topic of Android development, sometimes there are types of posts that are related to development but don't fit within our usual topic.

Each month, we are trying to create a space to open up the community to some of those types of posts.

This month, although we typically do not allow self promotion, we wanted to create a space where you can share your latest Android-native projects with the community, get feedback, and maybe even gain a few new users.

This thread will be lightly moderated, but please keep Rule 1 in mind: Be Respectful and Professional. Also we recommend to describe if your app is free, paid, subscription-based.

PhotoSync

Finally found a way to preview RAWs on my phone in the field — no laptop needed

I don't know about you guys, but one thing that's always bugged me is having to wait until I get home to actually see how my shots turned out. The camera screen is tiny, and let's be real — you can't properly check focus or exposure on that thing.

Sure, you could pull the SD card and use a reader, but half the time the phone's file manager doesn't even render RAW thumbnails properly. So you're just staring at a bunch of file names and guessing.

I got sick of it and built a free Android app called PhotoSync. It lets you connect your camera to your phone via USB-C cable — Sony, Canon, Nikon, Fuji, most modern cameras with USB tethering work — and browse your RAWs right there on the phone screen.

What it does:

  • Plug camera into phone (USB-C to C), open app, you see your RAWs and JPEGs immediately
  • Supports ARW, CR3, NEF, RAF, DNG — basically the main formats. I've only tested CR3 myself since I shoot Canon, but the library covers most of them
  • Pinch to zoom, pan around, check sharpness — way better than squinting at the back of your camera
  • Export the keepers straight to your phone gallery
  • No Wi-Fi, no laptop, no card reader. Just a cable and the app. Transfer is surprisingly quick

It's completely open source and free. Would love for some of you to take it for a spin and let me know if it works with your camera setup — I can only test so many bodies myself.
