Mold Identifier

Found a dark patch on the bathroom ceiling and don't know whether to worry?

Mold Identifier reads a photo and tells you what you're probably looking at, how serious it is, and exactly what to do next — including the thing most people miss: where the water is coming from.

WHAT YOU GET

• Photograph the growth and get the likely mold type in seconds
• A clear risk level, plus four dials for seriousness, danger, exposure and urgency
• The likely moisture source — condensation, a leak, rising damp — so it doesn't just come back
• The protective equipment to wear before you touch anything
• Ordered, practical cleanup steps written for the surface you actually have
• Health warnings and who in the home is most at risk
• A prompt to call a professional once the area passes the roughly 10 sq ft (1 m²) line health authorities use
• Ask follow-up questions about your result and get straight answers
• A built-in guide: how to photograph mold well, the common indoor species, safe cleaning, and when DIY stops
• Collections to group scans by room, property or visit — useful when you're documenting damp for a landlord or an insurer
• Export everything to a backup file you own

BUILT FOR ANDROID

Material 3 throughout, with light and dark themes, optional wallpaper colors, a layout that adapts to tablets and foldables, and square feet or square metres to suit where you live.

PRIVACY & CONTROL

Only the photo you deliberately pick and the prompt are transmitted, over an encrypted connection, to the AI processing service that produces the result — no account, no name, no location. Nothing else leaves your device, and you can switch AI analysis off entirely in Settings. Your scans, photos and conversations stay in the app's private storage on your device until you delete them or uninstall.

If the AI ever produces something wrong or offensive, there's a Report button on every result and conversation.

ACCESS

Your first three identifications are included. Unlimited scans, follow-up questions and every feature require a weekly or yearly auto-renewing subscription. There is no free trial and no introductory offer — payment begins only after you confirm in Google Play, and you can cancel any time in Play Store subscriptions.

IMPORTANT DISCLAIMER

Mold Identifier gives AI-generated guidance from the photo you provide. It is not a laboratory test, a professional inspection, or a medical device, and it does not diagnose, treat or prevent any condition.

Mold species can only be confirmed by laboratory analysis, and results can be wrong. Treat everything the app says as a starting point, not a verdict.

For any health concern, consult a qualified healthcare professional. For growth larger than about 10 sq ft (1 m²), growth in HVAC or ductwork, water damage from sewage or flooding, or if anyone in the home is asthmatic, immunocompromised, elderly, pregnant or an infant, consult a licensed mold remediation specialist.

Mold Identifier is an independent tool and is not affiliated with any testing laboratory, remediation company, or public health body.
