Support project development
The app is developed after hours as an independent project. I am currently raising funds to cover the Apple Developer Program license (approx. USD 100 per year), which will allow me to release the app on the App Store for iOS users. This goal is funded by future ads, PRO purchases on Google Play, and community support. If you choose to contribute, please remember that all payments are entirely voluntary donations toward project development. Thank you for every bit of support!
