Free Mobile and Android app maker
YES you thought it was closed down n but its back again. the popular google app inventor is back thanks to Mit.edu who have brought the “appinventor” back to the people to enable them to make apps without having to dip into their pockets for cash.
There are other online mobile app makers like widgetbox , but they charge anyway from $25 per month/per app to $100 per month /per app which can be a bit too pricey for a average user. i have done a demo app building on their interface and its pretty easy to make a mobile app at widgetbox
The appinventor from Mit.edu is free to use, though it does not have the advanced interface like widgetbox
There is another online app builder called http://ibuildapp.com/ as well but i have not checked it out.
