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/

Your dunk just got a deadline. Pick your goal — touch rim, grab rim, or throw one down — set the date, and let's get to work. Dunk by builds you a personalized plyometric program that scales to your timeline. Six weeks out? We go aggressive. Six months? We build you up right. Either way, every single day has a purpose. Real coaching, not guesswork. All 21 plyometric, strength, foundation and mobility exercises come with real video or image demos and coaching cues, so you're training with correct form from day one — no guessing, no wasted reps. Your countdown, your plan. Daily workouts are laid out with sets, reps, rest, and built-in rest days.

Every 4 weeks we re-test your vertical and chart the inches you've gained. Watch the number move. Watch the game change. Create a squad. Your 0-99 Dunk By Score ranks you against your friends or teammates on a live leaderboard. Climb the tiers, stack streaks, complete weekly challenges, and fill up your trophy case.

Verdict

The call

The clearest difference is ads: Dunk By at none against GoTall's shown. Dunk By also leads on rating (5.0 vs 4.6) and update cadence (every 3 days vs every 9 days). GoTall's advantage is ratings volume (6.8K vs 1) and iOS requirement (15.4 vs 18.0). On price, in-app purchases, monetization model and device support there is nothing between them.
