Have you ever wondered what physical characteristics your voice conveys about you to others? Your voice is a very powerful tool, and it can be used to estimate several things about you, such as your height, age, and gender.

The app is very simple to use:
Speak one sentence into the app.
Oben’s algorithms will estimate "How Tall" you are, your gender, and your age.
You can then take your selfie and share your HowTall stats with your friends and family - and compare stats with them as well!

The science behind our technology can be found on our website. Note that the algorithm improves with time and works best for heights between 5' 2" and 6' 2". We shall be expanding this range in future versions of this app. We also welcome you to correct the output if you see any errors - this will help us improve our predictions!

Gets an A for tech and effort

The app makes some fairly good assessments based just on voice, and I was surprised with how close it was able to determine my height and age (It gave me 27 and 5'11" vs 25 and 5'9"). Hope to see more from them.

don't even bother


This app is pointless and it was a waste of my time. Really stupid.

i wasn't sure what height was and then found this


awesome app
