    I am planning on getting a windows phone, and was wondering how the trial apps in the marketplace work. Are they time limited, or are they simply a cut down version of the full app?

    More of a cut down something you'll want is missing usually the coolest part of the app

    like BIG D5 Said

    ether

    - your missing parts of the features
    - or it can give you FULL access for limited time
    - it can give you FULL access but with adds. (which is the free version but still considered trial on some apps )

    I have an issue with trial apps. They should give full use for a limited time, so you can decide whether or not you want it.

    I asked this question last year and the explanation I got from a dev was that the app had no way of maintaining a date/clock register within the app, so no easy way to use a date/time countdown. That may have changed with the new APIs that came with Mango. Not sure.

    I haven't tried it myself, but I don't see why devs couldn't keep track of the time. The events to do this are already there. Just check the time on Application_Launching or Application_Activated and compare it to the time on Application_Deactivated / Application_Closing. Unless I'm missing something, that seems pretty simple to me.

    The way the trial works its completely up to the developer. My trials are always fully featured, but you can only use them 5 times for example.

    yeah there a problem with that doh ...

    if you chaneg the time/date on your device you could have the TIME Trial for ever.....

    they did that with BB apps and caused allot of Piracy problems. . (not sure if ti works with WP , but i dont see why it wouldnt )

    Think best bet si FULL features , but can only use a maximum of 5/10/15 times ..ect…

    Yeah as others have said, you can pretty much reference a conditional of "isTrial" when you're writing apps, and decide whether or not this part of the code will be accessible because of it.

    The problem with going time or number-of-use based is that all a user has to do is uninstall your app and then download it from the marketplace again to re-start their trial. Which is why Microsoft recommends you close off certain parts of the code in a trial situation.

    Obviously I prefer the unlimited time/number of uses but with adverts model, then lock out a few features that go above and beyond what you might expect for free.

    I have seen apps that have like a 3 day trial period. Sometimes whe you pay for an app to see the full version, you discover you don't like it.

    Again, pre-Mango I believe there was no database capability within an app, so I don't think they could record occurrences or start/end times. Some apps with time/day limits connected to a server, which could track your events. I do remember an app with a time limit that I used for about 4 months before finally couging up the 0.99. Simply forgot it was still a trial.

    Thanks jimski, I was not questioning your theory. I should have made myself more clear. In the past with phones I have had, I have seen apps with trial periods.
    For example when I had my Blackberry, Berryweather was an app with a 3 day trial period, then you had to buy it.
    But at least you had use of the full version so you can decide if you like it or not,
    I just think its a good idea.
    It's not a big deal, like the saying goes. It is what it is.
