Evaluating paid apps on App Store is troublesome

I bought an iPad recently and spent some time on App Store reviewing apps. I liked few apps but there was no way i could test them without first paying for them. For example, i bought an app yxplayer and after it's installed, i found that it's quite buggy. It has too many issues like:

• Video is not synced with audio
• Playing videos directly through Samba server (from NAS) is very slow
• Video quality is not good

In short, i bought a bad app but i had to pay for it first. It's very bad. Apple should devise some mechanism that can allow users to first install the app and then decide whether they want to to buy it or not. It will save our money.

If you are looking for a video player for iPad that can play any video format, try OPlayer HD. It also offers a Lite version which is free but offers the same features as that of full version. It works great and video quality is also awesome. Just a tip for App Store users, when you need some app, always look for a FREE app first. I'm sure, you will find some free apps that can do what you want.
