Thanks for your comments... if its a paid, whats the best price people pay without bothering too much.... any comments are very much appreciated. Have a great day
The argument rages on this site so read the posts you will find here for the insight it will provide. Personally I dislike the whole free concept but you will find that several apps have a full paid version and a lite version with ads.
As to price there are many many apps on the app store so you need to look at your development costs and be prepared to try things out. As beginner myself it appears that marketing your apps is vital to get it into the public eye. There are pages of apps in some categories so you will be up against many similar looking apps & need to stand out in some way.
Of course for the developer, you would want to publish paid apps and earn from them. Though if you do not have the luxury of waiting and having sales, you could make do with free apps using ads. You can employ the game play itself to let players earn from clicking ads. There are a lot of games like that.
