Hi,
We are a tracking service provider. Our services are based on both hardware as well as android based. We have a demo android application ready. If you are looking for the same, we shall fine tune it and provide. Would you also like to have the tracking application over the web? It will be based on yearly subscription. If you looking to track a number of users, we shall provide you that also at additional cost. Please let us know your exact requirement. Thanks.
Best Regards,
Sattlas.
