# Support

Something not working?

Write to us. Your mail reaches the two people who wrote these apps, and we answer it ourselves.

feedback@beyondsimulations.com


Before you write

Tell us which app you are using and what you expected to happen. If something went wrong, the version number helps more than anything else, because it tells us which build you are on.

Every app has an About window with its version in it, and a Send feedback link that fills the version in for you. That link is the fastest way to reach us.

Refunds

Apple handles every purchase, so Apple handles refunds too. Ask for one at reportaproblem.apple.com.

We cannot issue a refund ourselves and we never see your payment details.
