The Problem

People try to whiten and improve their smile but have no honest way to tell whether it's working — phone photos lie depending on lighting, angle, and camera, and there's no daily reason to stay consistent.

The Solution

A private, on-device tracker that scores your smile under locked lighting, turns progress into a streak and a 30-day plan, and shows a real side-by-side before & after — no cloud, no subscription.

Overview

SmileStreak snaps your smile, scores it 0–100 on brightness, evenness, and whiteness with on-device AI, then guides you through a 30-day glow-up program with before & after tracking. Lighting is locked after your baseline so progress is real, not a better angle. Everything runs on your iPhone — no cloud, no account. One-time $9.99 unlock.
