Email support@kicktechnic.co.uk. That is the only support channel, and a person reads every message.
There is no ticket system, no support forum and no chatbot — these are small apps built by one person, and email works better than a queue that pretends otherwise. Please say which app you are using and, if you can, its version number and whether you are on Windows or Android. That is usually enough to answer you on the first reply.
Bug reports and feature requests are welcome by the same address.
