GoTall is the most accurate height predictor. Here's why it works: 1. We use real science. GoTall uses data from the CDC, a group of top doctors and scientists who study how kids grow. 2. To guess your true potential, we ask about: Your parents' and relatives' height (because your genes matter) Your sleep, food, and activity (because habits affect growth) Your stage of puberty (because timing matters) We look at the full picture. Instead of guessing from just your age, we look at everything together. That’s why our results are more accurate than just using a growth chart. Stick to the growth plan, and we’ll keep guiding you every step of the way. GoTall gives you a custom growth plan that includes: Daily exercises proven to support posture, bone strength, and natural growth hormone activity Nutrition analysis that checks if your diet supports optimal growth Lifestyle tracking so you can improve sleep, habits, and recovery We also offer premium features with subscriptions or purchases, such as a custom plan designed to support natural HGH production and optimal growth, or monthly updates that adjust your plan based on your habits and progress, so you can stay on track. Disclaimer: GoTall doesn’t offer medical advice. Our recommendations are based on widely known practices related to height growth. Always speak to a healthcare provider for individualized guidance. Some features, including full analysis and advanced tools, require a premium subscription or purchase. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Track protein without turning meals into homework. Buff Kitty is a protein-only tracker for lifters who care about hitting one number every day. No calorie diary. No macro spreadsheet. Just your daily protein target, fast logging, and a gym cat that reacts as you get closer. Set your goal once, then log protein in seconds: - Quick-add the amounts you log constantly, straight from the dashboard - Type the grams when you already know them - Say what you ate when typing is annoying - Snap a meal photo and get an editable AI estimate - Scan a barcode for packaged food - Every estimate is yours to edit before it saves - Today's total, what's left, your streak, and recent entries on one screen Works the same whether you're bulking, cutting, maintaining, or recomping. Build a streak by hitting your protein target, and choose the reminder settings that work for you. Sign in with Apple or Google if you want to back up your protein target, food log, and Kitty progress, then restore them when you reinstall or change phones. Sign-in is optional. Manage your backup, email preferences, and account deletion in Settings. Buff Kitty is a subscription app. Setting your target is free, and a subscription unlocks tracking, the AI estimates, streaks, and the home-screen widget. AI estimates can be wrong, so check them before you save. This is a tracking tool, not medical advice. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
