Cephalon Navis is a free Android application developed by SlayerOrnstein. The app uses WarframeStat.us API to provide essential and helpful information to players travelling through the solar system, without leaving the game.

The app's main features include in-game news, world events, open world cycle timers, bounties, void fissures, nightwaves, Darvo's daily deals, Baro timer and inventory display, and sorties and invasions. The app is user-friendly and has an intuitive interface that is easy to navigate.

Cephalon Navis is an excellent tool for Warframe players who want to stay up-to-date with the game's latest developments. However, the app's support is only available through the developer's Discord channel, which may be a drawback for some users.
