# Supporting TwinDesk TwinDesk is free and open source, built and maintained by one person in their spare time. You don't need to pay anything to use it, and nothing in the app is held back for supporters. ## What support would pay for Two things cost money every year and are what keep TwinDesk from reaching more people: - **Publishing the iPhone and iPad app.** The App Store needs a paid Apple Developer Program membership. Until then the iOS app can only be built from source. - **Signing and notarizing the Mac app.** The same membership lets the Mac app be signed and notarized, so macOS opens it without Gatekeeper warnings or the "damaged app" message. Anything beyond that goes to test devices and the time spent fixing bugs. ## How to help If you'd like to sponsor TwinDesk, or help in another way (a developer account, test hardware), please get in touch: contact [@InukaAsith](https://github.com/InukaAsith) through the GitHub profile, or open an issue titled **Sponsoring** and we'll take it from there. You can also help without money: report bugs with logs, test betas on your devices, translate the app, or tell others about it. Thank you.
