What it is

The Drop is confirmed still in pre-order status only (a "Pre-order Now" Stripe link, no shipping date given) — it has not begun shipping. The company's separately live product is a WhatsApp-based conversational AI nutrition coach, offering AI-powered calorie tracking via photo or text, personalized workout recommendations, and daily nutrition reports through a chat interface that "feels like texting a friend."

Integrations
Useful for
Other ai food trackers
Deliberately minimal, Apple-Notes-simple interface for logging meals in plain language, built and marketed transparently by a single independent developer.
100+ selectable AI coach personalities let users pick a tone/style that fits them, rather than one fixed coaching voice.
Deliberately gamified design ("built to feel more like a game than a diet app") rather than a clinical tracking interface.
