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.

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 Appchkr type in this new license and your installation must match for license activation to succeed in the installed product. Choose the same for both. They may be chosen in either order. The matching is required only at activation, once both exist.


Appchkr License Types

  • Monthly subscription, paid and cancellable monthly. All software updates are received automatically. Adjust target count levels and charges anytime, manually via the website, or automatically via Appchkr's unique Auto-Flex charging option. Locked-in price protection.
  • Yearly subscription, paid and cancellable annually. All software updates are received automatically. Adjust target count manually at any time. No Auto-Flex charge option nor price protection. Savings over 12 monthly subscription payments.
  • One-time purchase, paid once, non-cancellable. Valid indefinitely for the release in which it is activated. Purchase additional target count and/or an Appchkr software update at any time. No Auto-Flex charge option. Savings over multi-year subscription costs.
