Features & Use cases
Computer vision
Run object detection, segmentation, and image classification. React Native ExecuTorch supports models including YOLO, RF-DETR, MobileNet, and Segment Anything (SAM), giving you a full computer vision toolkit.
From background blur in video calls to product recognition in retail apps – real-time object detection is the feature end users will notice.
Voice capabilities
Add studio-quality speech synthesis and accurate transcription to your app. React Native ExecuTorch ships with Whisper for speech-to-text and Kokoro for text-to-speech, so users can listen to content or dictate input even when they're offline.
Build an audiobook reader, a voice note app, or an accessibility tool that works even on a plane.
Image & text embedding
Generate vector embeddings from images and text – enabling semantic search, similarity matching, and local RAG without a cloud vector database.
A great fit for note-taking apps, photo managers, or knowledge tools – with the entire embedding and retrieval pipeline kept local.
LLMs & VLMs
Run large language models and vision-language models. React Native ExecuTorch supports Llama, Phi, and other popular open models.
Build AI-powered chat, smart autocomplete, or image-aware assistants – for apps where privacy isn't a feature checkbox, but the entire product.
OCR + LLM Pipeline
Chain OCR and an LLM together on-device: snap a photo of a sign, menu, or document in any language – React Native ExecuTorch extracts the text and feeds it to a local language model.
For travel apps, document assistants, or translation tools – like Google Lens, but private and offline.

Built a real-time voice conversation loop in @expo. Speech-to-text runs locally using @swmansion's react-native-executorch + Whisper. Transcribed text is sent to a local model, generates a response, then gets converted to audio via OpenAI TTS and played back with expo-audio. All on-device. Fast + seamless.

It does, it performs very well, probably best performing framework for mobile/edge right now. Comparing directly with a PC is kinda rough since it's hardware dependent. A PC with an RTX 4090 is going to blow away the theoretical performance max on an iPhone, the wattage alone is at least an order of magnitude. I'm getting 10 t/s for llama 3.1 8b on an S24+ You can easily get your hands wet by following the instructions on torchchat which gives you demo apps for Android and iOS or checkout the react native executorch wrapper. Both are pretty easy to get rolling with.
