Thanks for using our apps. If you like our apps and would like to support us, please make a donation using PayPal or Patreon. We are a startup company without any funding or investor. We provide our apps as free. We monetize our apps with inexpensive in-app products, ads and  partnerships. We would like to develop new apps and games and update our apps with more free premium features with less ads. You can support us with any amount of donation you want. We will upgrade our 4 year old notebook in order to develop faster. We also need a bluetooth midi keyboard to add Bluetooth midi keyboard support to our piano apps. Thanks for your support!
