The reference server is an Android app so yes, that is probably the point of the default design, but reading the README I believe you can also use a more traditional server-to-server setup:
DeltaChat/ArcaneChat Integration
DeltaChat and ArcaneChat are perfect companions for Tyr. These are messengers that use email protocols but provide modern chat interfaces. When you configure DeltaChat/ArcaneChat to use Tyr's local server:
1. DeltaChat/ArcaneChat sends messages via SMTP to Tyr
2. Tyr wraps them in Yggmail protocol and sends through Yggdrasil
3. The recipient's Tyr receives the message via Yggdrasil
4. Their DeltaChat/ArcaneChat fetches it via IMAP from their local Tyr
5. All this happens peer-to-peer, with no central servers
If you run Tyr on a VPS/RPi/old smartphone, you can still exchange messages decentralised this way, as long as your server and the device/server you're communicating to are both online, and have DeltaChat/ArcaneChat fetch the messages later.
Such a setup could be useful if you find people around you using Tyr and you're losing messages because your phone kills the app, though a PoC like this probably won't have much of a network effect.
