SMULE is Basically a Music application. It is A Good platform to explore our Talent.But I am not 100% Satusfied With Smule as There are many disadvantages of using it.Firstly , It contains a Lot of Ads, That really disturbs while singing and Remove the flow.Secondly , Sometimes The songs which we want to sing alone without Any partner is Not Possible .If we want to sing alone and want to make our own album we have to pay money. It is not free of cost.The filters and sound quality they provide get rubbish and the speaker loses its tempor.Overall it is not the best app.About rating I would like to give 2/5 stars to SMULE.Star maker is actually better than Smule. Better to try Star Maker if you are really serious about your music and Singing.
