Auto-Flex Charging

All Appchkr monthly 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 for all Appchkr types 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.

Only available with monthly subscriptions, not for yearly subscriptions, nor one-time licenses.


The free verion of an Appchkr must be updated occasionally to the current release, always freely available from this site, in order to continue operating.


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.
