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/

About

Nanbit

Features
Read full description

Nanbit is a calm habit tracker. Add a few habits, pick the days each one is due, and tick them off. TODAY The day's habits in one list. Tick one and it moves down, done. The week strip takes you back to a day in the past week that you forgot to tick. TIMER Give a habit a timer. When it ends, the tick is counted for you. HISTORY AND PROGRESS Every habit keeps its streak. History shows each month as a calendar, colored by how much you finished, and every past day to look back on. Progress shows each habit's month, compared with the month before. REMINDERS A daily reminder, and one for each habit at the time you choose. Nothing arrives for a habit you have already ticked in the app. A WIDGET The small Today widget shows on your Home Screen how many of the day's habits are done. NANBIT PRO An optional subscription, Yearly or Monthly: • Unlimited habits. The free version keeps five. • Every widget: medium and large widgets that list today's habits, a widget for one habit with its streak (iOS 17 or later), and Lock Screen widgets. On iOS 17 or later, tick habits right from your widgets, on the Home Screen and the Lock Screen. • Smarter reminders: up to 3 a habit, plus a nudge that comes only if the habit is not done yet. • 12 color themes, and the app icon in the same colors. • Your whole history: change any past day, and see the Year view. Payment is charged to your Apple Account at confirmation, and the subscription renews automatically unless you turn it off at least 24 hours before the period ends. To manage or cancel it, open the Settings app, tap your name, then tap Subscriptions. You don't need a subscription to use Nanbit. Your habits are kept on your phone, and Nanbit sends them nowhere unless you choose to sign in for an optional, free backup. No ads, and no analytics about how you use the app. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://lemiarino.github.io/nanbit-pages/privacy.html
