Now tracking 8 major UK supermarkets — find where every pound of protein goes furthest, updated daily. New recipes added regularly.
Protein Spy tracks the cheapest protein per pound at every major UK supermarket, every day.
Whether you're chasing gains, feeding a family, or just tired of your protein bill creeping up, Protein Spy shows you where each pound goes furthest — right now, today.
What it does
• Compares chicken, beef, fish, eggs, dairy, plant proteins and whey across Tesco, Sainsbury's, Aldi, Lidl, Waitrose, Asda, Morrisons and M&S.
• Ranks everything by pence per 10g of protein — the only fair way to compare a chicken pack, a tuna multipack and a whey tub.
• Updates daily so you're never shopping on last week's prices.
• Filter for vegan, vegetarian, red meat, white meat, fish, dairy or powders.
• Tap any item for a full breakdown: pack size, protein content, price per kg.
High-protein recipes, costed live
Every recipe in Protein Spy is priced live at each supermarket using today's data. Chicken fried rice cheaper at Aldi tonight? Lentil dhal at Tesco? The app tells you where your basket wins.
Freemium, honestly
The full price radar is free forever, ad-supported. Premium (£2.99/month) unlocks the full recipe library and removes ads. Cancel anytime.
