Quick and Simple
Paying with credit card [MJ]

All Appchkr subscriptions include the option to vary the monthly charge automatically, in step with the target count level actually in use, both up and down. This option is provided in all Appchkrs without additional charge. Pay only for what you use, as it varies, without any extra effort on your part. Others may claim to save you money. We give you the means to actually do so.


The subscription type and installed Appchkr type must match for subscription activation to succeed in the installed product. Be sure to choose the same for both. They may be chosen in either order. The matching is required only at activation, once both exist.

Choose an Appchkr subscription type to match your installed Appchkr type.

    What is a target?
  • One target is one networked application running on one machine and listening on one port.
  • That program running on 10 machines constitutes ten targets.
  • Ten instances of that program (on ten different ports) running on one machine likewise constitute ten targets.
  • If that application uses two ports, both of which need to be checked, it constitutes two targets.
