I know the guy (well know online) who made these altimeters for the rocketry hobby. https://flightsketch.com/store/catalog/flightsketch-mini_1/ https://flightsketch.com/store/catalog/flightsketch-mini_1/ he went from idea to prototype in 6 months i think. Pretty amazing if you ask me. Edit: oh i was just looking at the images scroll by and saw a screenshot. I did a rework of the mobile app for him, i totally forgot about that. (i used ionic)
