Spookstr
Spookstr is a paranormal/cryptid/UFO app that pulls posts from Nostr that run along those lines. Users can see posts from others and make their own posts. In the future Spookstr aims to have its own relay so that Spookstr can become a real community app.

Debt Reaper
A very scary clock with the current US national debt! Because what is more scary and haunting than that!?!? [For sample showcase if you want it].

Halloween Storybook
This is a simple and cute (not very spooky) children's Halloween story about a cat who learns a life lesson at Halloween while also learning about Bitcoin. It's wholesome. [For sample entry, the cat didn't make this and he isn't allowed to have a wallet so he can't win]

Hexed Notes
Put a hex on your notes and let your friends cast spells to remove the hex and decode your secret message.

Haunted Relay Scanner
Wander the haunted forest of Nostr relays. Alive trees glow with activity while possessed ghosts wait to be revealed. Keep the controls within reach and monitor the hunt without losing sight of the action.
