OnDevice AI is a powerful AI assistant built by OnDevice AI Inc. that runs entirely on your Android phone using Google's Gemma language models via the LiteRT inference framework. Unlike ChatGPT or Claude, which route every query through cloud servers, OnDevice AI performs all inference locally on your device. It works with or without an internet connection, costs a one-time fee starting at $3.99, and accepts M-Pesa, MTN MoMo, and card payments. It runs on phones with as little as 3GB RAM, including Tecno Spark, Infinix Smart, Redmi, and Samsung A-series devices.
“Works on my Redmi even when Safaricom network is completely down.”
AI should work for everyone. We built it to run on the phone in your pocket.

Prompt
Explain the process of photosynthesis for my WAEC Biology exam. Include the light and dark reactions.
Response
Photosynthesis occurs in two stages. The light-dependent reactions take place in the thylakoid membranes, where water molecules are split using sunlight to produce ATP and NADPH.

Common Questions
Is this safe to install? I worry about scams.
This is a legitimate product from OnDevice AI Inc., a registered company in Ottawa, Canada. Payment is processed by Stripe — used by millions of businesses globally. The APK does not request suspicious permissions and all AI runs locally on your phone.
Is there a subscription or hidden charges?
None. You pay $4.99 (₦6,800 / KSh 640 / R82.57 / GH₵55.13) once. No monthly fees, no data charges, no in-app purchases. The AI is yours forever.
How does this compare to ChatGPT or Claude?
ChatGPT and Claude run on cloud servers — every message requires internet and a monthly subscription. OnDevice AI runs the AI model directly on your phone. You pay once, own it outright, and use it with or without a connection. Different architecture, different tradeoffs — both are real AI.
How do I know it truly works without internet?
After installing, turn on Airplane mode — cut all Wi-Fi and data. Open the app and ask anything. You'll get a response. Nothing is ever sent to a server.
What Android version do I need?
Android 9.0 or higher. Works on most phones made after 2018, including Tecno, Infinix, Redmi, and Samsung Galaxy A-series.
What if I lose my phone or get a new one?
Email your original receipt to support and we'll resend your download link. One purchase covers you across devices.
Will it work on my phone?
Requires Android 9.0+ and at least 3GB RAM. Works on Tecno Spark, Infinix Smart, Redmi, Samsung, and most modern Android phones.
