iOS app ‘Baby Growth Chart’ ver2.1 released

‘Baby Growth Chart (Lite)’ ver2.1 were released the other day.
Both new paid and free apps use some cubic Bezier curves for percentile curve though previous versions used n-degree approximation curve (n were about between 5 and 9).

So I decided to use Bezier curve to draw lines more naturally, I made one iPad app to make Bezier curve like this :

New version app draws Bezier curves, so I’m satisfied but I know there is something to do yet, I will fix them at the next version.
