Centile now shows one clear result: the best range it can work out at your age, and how we got it. Growth charts say which reference they use at each age.

Log today's exercise, food and sleep in one place. The growth chart now shows the same three lines at every age, with the average clearly labeled. Plus explains why its range differs from the parents'-heights range. Small fixes and clearer wording.

Centile now grows with your family, from birth to 19. Add a child of any age, see their growth since birth, and track sleep, active time and calcium together. When a teen is ready, move their record to their own phone.

Plus now shows your growth chart, how you compare with others your age, how close you are to your adult height and your chance of reaching your dream height.

You can now ask a parent to help you get Plus. Small improvements to the Plus range.

Your free range now needs just three things: your mom’s and dad’s heights and whether you’re a boy or a girl.

Your free range is always one tap away, and purchases a parent approves now switch on by themselves.

Share your range, and see when you pass a parent or grow since your last check.

Setting up is quicker: you can leave weight for later and still see your range straight away.

See your Plus range ready the moment you finish set-up, and try Plus free for 3 days. Results switch between cm and feet and inches with one tap.

The Plus page now shows the launch offer clearly: your first-year price, the normal price after it, and when the offer ends. Monthly height-check reminders now carry on past the first year, and there are a few smaller fixes.
