If you love my apps, please consider making a donation. As a developer, I make 70% of sales when purchased (30% goes to Apple). For those who get my apps during free campaigns, I make no money. Because I'm an independent freelance app developer, my app is virtually unknown to the world, which is why I must do free campaigns. For better user experiences, I choose not to charge you after the apps are installed. Until my apps become internationally successful, I need your support to maintain them! Please also write a positive review so the apps are better recognized.
