Our founder Jens Knoops has had a strong relationship with chocolate since his childhood in rural Germany. In 2013, he decided to share his passion and opened the first Knoops store in Rye, East Sussex. Since then, Jens has gone on to open more Knoops stores, built a team of chocolate lovers around him, developed an at-home range of chocolate flakes, and even released a chocolate cookbook. The Knoops concept is based around our carefully curated percentage menu which offers chocolates to suit every taste and mood. We find joy in helping you to discover your perfect chocolate drink, and encourage experimentation with different % chocolates and flavours in a process we call ‘Knoopology’. This process is simple;choose your chocolate %, milk, and extra flavours like sea salt, orange zest or chilli to be made into a hot chocolate, milkshake or iced chocolate. With our app, you can get rewarded for your experimenting with Knoopology by collect points with every drink you buy in our stores.

Know what is in your food, even when there is no signal. Lifyzer scans products in its installed catalog and turns nutrition facts into a clear, explainable rating. Barcode lookup, package-text recognition, search, scoring, history, and favorites work on your iPhone from first launch, including in airplane mode. WHY LIFYZER • Fully offline: 75,000 curated food products are included with the app. • Private by design: no account, ads, analytics, scan telemetry, or product API calls. • Easy to understand: see an A to E grade, a 0 to 100 score, and the nutrients that influenced it. • Fast local search: find installed products by name, brand, or barcode. • On-device scanning: Apple system frameworks process barcodes and package text locally. • Yours to keep: scan history and favorites remain in private app storage. EXPLAINABLE, NOT MYSTERIOUS Lifyzer-NPM-1 applies the published UK Nutrient Profiling Model 2004/05 tables on your device. Product pages show the nutrition values behind each result, including energy, sugar, saturated fat, sodium, fiber, protein, and plant content. NO FORCED DATA DOWNLOAD The curated catalog is ready when the app opens. Lifyzer never checks for updates in the background. If you choose to update it, you stay in control by importing a compatible local dataset file. IMPORTANT Catalog coverage is finite, so some barcodes may not be installed. Lifyzer never guesses a missing product or silently sends it to a web service. The Lifyzer rating is a comparison aid, not medical advice and not an official Nutri-Score. Product information is derived from Open Food Facts under ODbL 1.0 and may be incomplete or inaccurate. Always check the package, especially for allergies or medical needs.
