    From a review:

    The Pro version YOU PAY FOR has a built-in TIME BOMB which periodically disables it unless you go online for a "Liceense Check"

    While that might not bother some ppl I hate any app that needs to periodically renew a license. Especially for a paid 'pro' version…

      I installed app and could not find any option to renew or register license. On About tab under license it is 'Personal' and no option to change. Can you please see if there is any such option to register or renew.
      Also Developer has replied to refund money.
      Still it will be better to have more information for everyone.

      Why is that? Do you have a device that never connects to the internet? I think it's a pretty good way of combating piracy and assuming the company is somewhat competent, if they were to go bust one day they can always disable the feature.

        The pirates are using the app for free without the stupid, annoying, inconvenient license check. All it's doing is annoying paying customers like DRM usually seems to.

        • MadJD on 31/07/2017 - 18:33

          Exactly right Diji1. Its not a successful method and doesn't stop anyone from pirating an app.

          But it also raises lots of privacy issues and when its not disclosed in the first place even more so. Hows does it activate? What information does it send and to which server? Is it all through google play or has the developer setup their own private activation server?

          @MadJD: "Google Play license check" is listed in the permission details.

        • MadJD on 31/07/2017 - 23:21

          Thank you! :)

          I wouldn't have thought it would mean periodic checking but that is an option aparantly. Honestly this is the first time I've struck the issue.

          From the 'Licensing Overview':

          The Google Play client collects the necessary information about the user and the device, such as the device's primary Google account username, IMSI, and other information. It then sends the license check request to the server on behalf of your application.

          The Google Play server evaluates the request using all available information, attempting to establish the user's identity to a sufficient level of confidence. The server then checks the user identity against purchase records for your application and returns a license response, which the Google Play client returns to your application over the IPC callback.

          Looks like google handles all of it which makes me feel a little more confident.

    If anyone is looking for a free alternative, Desmos may suit - however it's scaling might be weird on some mobile devices.
    Their website version (https://desmos.com/calculator) is very good for your general web graphing needs, I highly recommend this for any high school students doing Methods/Spesh or similar.

      I believe, refund option is ,if we are paying $7.99. They have not updated text.

        There's nothing incorrect about this statement…. ? Because'thinking' is subjective, you could theoretically have 100 percent thinking they're better than everyone else.

        Maybe you missed the point of the first comment.

          You're absolutely correct.

      If you don't know what to put in you don't need it :-)
      For most folks degrees will do just fine.

      Radians and degrees are two types of units for measuring angles.

      Degrees are you'd expect, range from 0 to 360. If you stand facing north you start with 0 and if you turn halfway it's a 180 degree spin, and if you complete the revolution you'd do a full 360 degree spin. You might wonder why we have 360 degrees in a circle as opposed to a much simpler 100 degrees — the answer to that is due old habits of ancient culture

      However degrees are not real numbers, kind of like how a percentage isn't a number and to do any real math with percentages, you'd usually treat it as a decimal (e.g you'd treat 83% as 0.83 in a calculation). So you'd usually have to convert degrees into a decimal form too.

      Most of us use Degrees in everyday language, but in maths sometimes you'd like to do something more complex like finding the area of a sector of a circle, and that's where you might wish to use radians to express angles because it involves one less step (having to convert degrees to a decimal).

      Radians is a more mathematically pure method of describing angles and Khan explains it in detail here.
