Thanks for helping test Lafai: Your Food AI Companion! This short guide explains what the app does, its current limits, and how to give feedback.
Voluntary Participation
Joining the program is entirely optional and comes with no obligations. If the topics of lifestyle, food analysis, and AI chats do not match your interests, you can leave the program at any time.
The test period runs for about 3-4 weeks. If you are interested in continuing to use the app for free for at least one year after testing ends, simply include your Account ID (found in the app's Settings page) when you send your feedback. Feel free to send feedback at any time, not just at the end of the test period.
For Android users: Please try to use the app, if it is not possible daily, at least a couple of times every 2-3 days, as suits your interests. This helps meet Google's Closed Testing requirements for participation.
Note: The page will always be displayed in English. The page will change to 'You are a tester' and 'Leave the program' if you want to leave later (use this same page to leave the program).
Download and Install the app explicitly by clicking the link "download it on Google Play" on that page, which opens Google Play where you can press Install.
Step 1: Get the TestFlight app from the App Store if you don't have it.
Step 2: Tap "View in TestFlight", read about Lafai, and tap Install.
What Lafai Does
Point your camera at a food or label (or pick a photo) and Lafai uses AI (Google Gemini) to extract the nutrition info and give you a plain-language evaluation. You can ask follow-up questions, save scans to your Archive, and optionally create custom prompts or set a lifestyle profile so the analysis is tailored exactly to you.
Important Caveats
Beta software: Expect occasional bugs and changes. Builds may expire โ if you see an "update required" message, just grab the latest build from the Store/TestFlight.
Not medical advice: Lafai provides general nutritional information only. AI can be wrong or incomplete. Always double-check the actual label and consult a professional for medical or dietary decisions. Do not rely on it for allergy-critical decisions.
Your data: Scans, chats, and profile are stored securely on your device, meaning we have no access to your private data. Label or food images and (if provided) your custom prompt or lifestyle profile are sent to Google Gemini to produce the analysis. See our Privacy Policy.
Fair-use limits: There's a daily scan limit to control AI costs. If you hit it, you'll see a friendly message and can try again later (usually the next day).
What to Test
Scan different food labels (clear, blurry, multi-image, any language). Also try pet food, drinks, supplements, or any food without a label (e.g., fruits or food plates).
Read available prompts, or create your own new ones.
Send follow-up chat questions using the suggested text, free text, or by attaching a product.
Scan imported or foreign food products in any language.
Save, reopen, and start a new chat from a previous product.
Set your lifestyle profile in Settings and see how it changes your product analysis.
Switch your device language to see how the app adapts.
How to Give Feedback
Please report any issues, proposals, or ideas on what you would do differently. Helpful details include: your device + OS version, what you did, what you expected, what happened, and a screenshot if possible.
