Yellow Teeth
AI teeth whitening coach
The problem
Whitening advice online is a mess. Strips, gels, trays, charcoal, LED lights, oil pulling — every source tells you something different, most of it wrong or unsafe. People either overdo it and wreck their enamel, or give up after a week because nothing visible happens.
What Yellow Teeth does
Yellow Teeth takes the products you already own, asks a few questions about your teeth and sensitivity, and builds a 4-week routine that actually fits your day. Brush in the morning, strip at night, whitening pen on Wednesday — all on a schedule your phone nudges you to follow.
Every few days it asks for a photo. The app lines it up against your baseline and shows the shade change objectively, instead of you squinting into the bathroom mirror wondering if anything's happening.
Features
- Personalized routine. Generated from your products, schedule, and sensitivity profile — not a generic checklist.
- Smart reminders. Push at the moment that fits your day, not at 9am sharp when you're already at work.
- Progress photos. Side-by-side comparison with baseline, tracked shade by shade.
- Safety guardrails. Warns when a combination of products is too aggressive for your enamel, backed by dental guidelines.
- Offline-first. Works without a login. Your data stays on your device unless you explicitly sync it.
