Boilerplate
Fettle is a UK adaptive nutrition app founded by practising pharmacist Daniel Cheung. Its Adaptive Engine recalculates users’ calorie and macro targets every week from real weigh-in trends — explaining every decision on screen — then turns the resulting meal plan into a one-tap grocery checkout. Fettle launches on iOS and Android in early 2027. First month free, then £10/month. “Fettle” is a UK registered trade mark of Fettle Fitness Limited (UK00004371666). fettle.fit
Fast facts.
Story angles we can speak to
The pharmacist-founder:
A working community pharmacist building consumer health tech from what he sees at the counter — including the nutrition gap in the GLP-1 boom.
Why diet apps fail:
Static calorie targets describe a body that no longer exists within weeks — the case for adaptive, explained coaching over logging.
The engine written by a dietitian:
most diet-app algorithms are engineering-led. Fettle’s Adaptive Engine has its decision logic written by a registered dietitian, Simone Pigliapoco, and reviewed by a practising pharmacist — clinical judgement encoded as software, with every decision explained on screen.
The plan-to-checkout pipeline:
closing the gap between knowing what to eat and buying it, via the grocery-checkout integration.
