Workouts that build strong bones
School jumping programs improved bone strength in teens. TallPro's week mixes jumps, strength, sprints and stretching, with rest days built in.

- Fits your diet and allergies: vegetarian, vegan, halal and more
- Ate something else? Pick it from the list or snap a photo
- Dairy and water counters that fill as you go

Built on research
What the studies say
Every part of the plan comes from published research and health guidelines. Here are a few of them.
10 min
of jumping, twice a week for 8 months, improved bone strength in teens at the hip and spine.
Weeks et al., J Bone Miner Res, 2008 ↗+0.4 cm
more growth per year in trials that added about a glass of milk a day, larger near the growth spurt.
de Beer, Econ Hum Biol, 2012 ↗Deep sleep
is when the biggest growth-hormone burst happens, early in the night, so bedtime matters.
Growth hormone & slow-wave sleep ↗−55%
melatonin when reading on a light-emitting screen before bed, and a body clock 1.5 hours later.
Chang et al., PNAS, 2015 ↗The honest part: genes decide most of your adult height, and no app can change that. Good habits help you reach the top of your own range and stand at your full height.

FAQ
Questions
Will TallPro make me taller?
No app can change your genes, which decide most of your adult height. What sleep, nutrition and training can do is help you reach the top of your own predicted range while you're still growing, and good posture helps you stand at your full height. We never promise a specific gain.
Who is it for?
Teens and young people aged 13 and up who are still growing, or who want better posture and habits. If you're under 18, use it with a parent or guardian.
How accurate is the height prediction?
It's an estimate based on published growth research and your answers, shown as a likely range with a confidence level. It gets more accurate as you add monthly height check-ins.
Is my data private?
Your name, answers and tracking stay on your phone. We only send what a feature needs (like a question to Apex or a meal photo to scan), we don't show ads or sell data, and you can delete everything in the app. Read the Privacy Policy.
Is this medical advice?
No. TallPro gives general guidance on training, food and sleep. If you're worried about your growth, puberty or health, talk to a parent and a doctor.
How much does it cost?
TallPro Pro is a subscription with weekly, monthly and yearly options, and the yearly plan starts with a free trial. You can also unlock just your height report once. Prices are shown in the app before you buy, and you can cancel anytime in your iPhone's Settings.
