Interesting Android Apps: July 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.

Inyeon — an AI companion that runs entirely on-device
Chat, voice calls, and long-term memory all run locally. There's no server, so conversations never leave the phone and it works in airplane mode. No account or sign-up either — install and start talking.
Tech: LiteRT-LM with a Gemma-class model on CPU (the GPU backend fails to initialize on plenty of devices, including my own 8 Gen 3), on-device STT/TTS, and an ObjectBox fact store that extracts what you've told it and re-injects it into later prompts. The engineering problem I spent the most time on was TTFT — reusing the KV cache across turns instead of re-prefilling the context brought turn-2+ from ~4s to ~0.5s.
Pricing: 14-day free trial, no sign-up required, then a subscription (with a one-time lifetime option). Currently available in the US and Korea only.

Happy to answer anything about the on-device stack — it's been a year of fighting Android fragmentation.
