Just wanted to give a shout out to Mobiscroll. I was struggling to improve the UI of my app and looked at open source calendars, buttons etc but it made my app very disjointed. Then I came across MobiScroll through another forum. Bingo! Their plugins really helped me improve the app tremendously. Some of the strong points include:
Quickly add native type elements (can segregate by device type)
Intuitive way to add elements
Provides a uniform look and feel throughout the app with professional looking elements (best feature)
Amazing support with next day turnaround
Check them out when you get a chance.
Thanks for reading!
