This is correct. FoxyTag database is now very complete and precise and the system became commercial in order to maintain the same level of quality. For that reason, partners (like TrackerTag) pay a fee to help covering the costs incured by the system. The price is however decided by the partner itself, so that he can cover his own costs if he wants so. But he can also provide his application for free, if it is ads-funded or if the partner simply wants to promote his work.
So, as long as we have at least one free application, we will still promote FoxyTag as being a
free, legal and collaborative system to signal speed cameras on mobile phones...
