Two apps live in this cave.
AppCave is a small independent studio. Games and tools made for people who own their devices — no ads, no tracking, no subscriptions. Pick a doorway.
PRISM
On Google PlayBend the light. Relight the Great Prism.
An optical puzzle game set in an abandoned observatory. Rotate mirrors, prisms, filters and portals to route beams of light through eighty hand-crafted chambers — every par proven minimal by a solver, so three stars are always honestly reachable. Daily puzzles, an endless trial, a weekly seal, and a real offline star finder. Free to start; one purchase opens everything.
Enter the observatory →OmniFiles
In developmentEvery file. One list.
A native file manager that puts your device, your NAS, your servers and seven clouds behind one honest interface. Encrypted search that reads inside documents and photos, transfers that survive reboots, native Synology administration, archives, and a Wi-Fi file server in your pocket — with no backend and no accounts. Self-hosted is free forever; Pro is a single one-time purchase.
