For all my apps I provide updates for free, regardless of when you bought the app. Further development is funded solely by new users, as I also do without alternative payment models such as subscriptions.
You can support me by honoring my work with a small contribution at Buy me a coffee.
Donating through Buy me a coffee is easy and done in seconds. No account or registration required. All major credit and debit cards, Apple Pay and Google Pay.
FastSpring
You can also support me through FastSpring. FastSpring supports all major credit and debit cards as well as (depending on your region) other services like Amazon Pay, Paypal and GiroPay.
