Do you actually know what's in the food you eat, the supplements you take, and the water you drink? Most people don't. And that's not your fault. Labels are designed to confuse, not inform. Marketing language like "natural," "clean," and "healthy" means nothing legally. And the apps that claim to help? Most of them are built on fear, not science. We built Klar differently. Science-backed scoring. Not fearmongering. Every product score in Klar is anchored to peer-reviewed science and official EU regulatory data. Not advocacy watchlists, not inflated thresholds designed to alarm you. When we flag an ingredient, we show you the EFSA scientific opinion behind it, the dose that matters, and exactly where the data comes from. You can check our working. Always. What you can scan: Packaged food โ Scan any barcode and get a score from 0 to 100 across five independent pillars: ingredient quality, additives and preservatives, processing level, contaminants, and nutritional profile. We use the NOVA classification system, the most scientifically validated framework for ultra-processed food, alongside the EU's own additive safety register. Every E-number is assessed individually. Not just flagged. Assessed. Supplements โ The supplement industry in Europe has no mandatory pre-market testing. A label can say 500mg and contain half that. Klar is the first consumer app to score supplements on label accuracy alongside ingredient quality and clinical evidence. We show you which products have been independently verified and which ones are asking you to trust their word. Tap water by city โ We mapped drinking water quality across major European cities using official EU monitoring data, including the new mandatory PFAS limits introduced under the 2026 Drinking Water Directive. Search your city and see exactly what's in your water, how it compares across Europe, and whether a filter makes a meaningful difference for your specific contaminant profile. Cosmetics and sunscreen โ Scored against SCCS opinions and EU cosmetic safety regulations, not fear-based ingredient blacklists. We tell you what the science actually says, at the concentrations that actually matter. What makes us different: Every score has a source. Every flag links to the scientific opinion or regulatory document behind it. When data doesn't exist for a product, we tell you. We never assume a product is safe just because it hasn't been tested. And when a product is recalled by EU food safety authorities, you'll know before it sits in your next shopping basket. We are built on open EU science. We are headquartered in Europe. We follow European regulatory standards, because that's where you live and shop. Transparency isn't a feature. It's the product.

Verdict
The clearest difference is in-app purchases: RestTap at none against Klar's 2. RestTap also leads on iOS requirement (13.0 vs 15.1). Klar's advantage is ads (none vs shown). On price, update cadence and device support there is nothing between them.
