Nutria: AI calorie-tracking app grown on organic TikTok, $46,900 MRR
Nutria (Calyra) is an AI calorie-tracking app that grew on organic TikTok rather than paid ads, verified at $46,900 MRR in the AI mobile apps category (median $24,600 MRR, $5 per customer). The model to borrow is the content engine pulling in $5-a-month subscribers — though calorie tracking is crowded and organic TikTok growth is hard to repeat on demand.
