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

★★★★★ SuperSpruce · Jul 8, 2025

The best app I've found so far for local LLMs on Android. However, due to my hardware (8 GB RAM, SD695), these models don't exactly run very well.

★★★★★ 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!

★★★★★ Kamen Stoykov · Jun 10, 2026

Goog application. I like the fact that I can load any GGUF model. It would be perfect if you add: 1. Option to choose between CPU/GPU (maybe NPU, but they are rarely supported) 2. Generation params per model 3. All Generation param could be just inputs rather than sliders.

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

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?
