Slab is a protein tracker that never shows you a calorie. Not buried in settings. Not calculated in the background. One number, all day: grams of protein, and how far you are from your target. Slab requires a subscription to use. Your first month is free, then $29.99 a year or $5.99 a month. THE STACK Everything you log drops in as a block, sized by the protein it added. A dashed line marks your target. You can read your whole day from across the room. ONE TAP The foods you actually eat sit on the home screen, most-logged first. Chicken breast, whey, Greek yogurt, eggs. Tap once and the block drops in. Most days you never leave this screen. FOR EVERYTHING ELSE • Search a catalog built from USDA data and curated by hand, not scraped from restaurant menus • Scan a barcode for anything packaged • Save your own foods once and log them forever • Type any amount, anywhere, and everything is in grams WHAT HISTORY LOOKS LIKE No charts to interpret. Slab answers the only question worth asking: how often do you hit your target. Hit target 24 of the last 30 days. The streak counts days you logged, not days you were perfect, because one bad Sunday shouldn't erase three weeks. WHAT IS NOT IN HERE No calories. No macro wheels. No food photography. No feed. No account to make. No ads. And no premium tier above the subscription you already have — search and barcode are part of the app, not an upsell. Your data stays on your phone and syncs through your own iCloud. It never reaches a server of ours, because we don't have one. Your first month is free. If Slab isn't the fastest way you have ever logged protein, cancel before the month ends and pay nothing. — Slab, yearly: $29.99 per year, with one month free Slab, monthly: $5.99 per month, with one month free Payment is charged to your Apple Account at confirmation of purchase. The subscription renews automatically unless it is turned off at least 24 hours before the end of the current period, and your account is charged for renewal within 24 hours of the end of the current period. You can manage or cancel your subscription in your Apple Account settings. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
