Run language models privately on your phone. No cloud, no internet, no tracking.

LM Playground brings private, on-device language model inference to Android, delivering offline chat and model loading without cloud or tracking. It supports custom GGUF models, per-model settings, and a rich Markdown chat experience. With 50,000+ total downloads and a solid user rating (3.96/5 from 341 ratings), it stands out as a privacy-first mobile LM playground.

Pros & Cons

Privacy-focused: on-device processing keeps conversations private and offline
Open source: MIT-licensed and community-driven
Custom models: load GGUF files from any source alongside built-in models
Rich UX: Markdown-supported chat and session management provide a polished experience

Larger models require substantial device RAM (8+ GB for 4B–8B models), which may limit usability on older devices
On-device inference can depend on hardware capabilities, potentially reducing accessibility on lower-end devices

Comments on LM Playground for Android

★★★★☆ Austin Wilson · Jun 14, 2026

Good app, but I wish it let you connect API keys for external LLMs, like openai or Gemini instead of only local models

★★★★★ Puffin Batteries · May 4, 2026

Best on-device LLM app on Android! The developer actually reads feedback and pushes updates fast. After reading my review, they added a 'Load Anyway' button for bigger models! Now my base Pixel 9 (12 GB RAM) is back to flawlessly running the massive Gemma-4-26B Q4_K_S (over 16 GB) model via mmap/swap at ~1 token a second. If clicky haptics (maybe 7ms) eventually get added, it would be even better!

★★★★☆ Dr Ajay Tripathi · Apr 15, 2025

Ok thanks help appreciated downloaded model but no option to delete it. It is also not shown as data linked to app so that after deleting app the model file remains. Pls tell how to delete downloaded model file?

There is no way to run already downloaded gguf models, according to own choice

★☆☆☆☆ Markus · Aug 9, 2025

The download in-app keeps pausing, if I download the exact model it wants, with the same filename and same size but manually from hugging face, it seems to not check that the model is already downloaded, tries to download the model again and appends the -1 at the filename, even tho I already have the model downloaded. And ofc that second download from the app itself fails and keeps failing, keeps pausing randomly, not a good experience, the app works great ig but downloading is a hassle as of rn

★☆☆☆☆ Corazon Jedi · Jun 9, 2025

Phone burns up using Gemma2 8b. I suspect all models using anything from 7-9b are bad for our phones. I have a Samsung 24 Ultra, which is a high-end phone. I'll scale down to a 1-3b model to see how that goes. Features I want to see in the future: Project feature Folder access to read files (ebooks) Voice capabilities Update: I don't like that there is no feature to delete a LLM. That really angers me more than anything. If there is, I do not see it. How do I delete a model?
