Tarius turns your phone into a shared songbook the whole band can follow, and a stage teleprompter that never goes dark on you mid-song. Done with paper binders, broken tablet apps, and scrambling for the right chord chart while the crowd's watching. Whether you play wedding receptions, café sets, or the main stage at a festival, Tarius keeps your setlist, your lyrics, and your chord charts exactly where the whole band needs them: in sync, in front of you, working every time.

AIRSYNC: SHARE A SETLIST WITHOUT TOUCHING A KEYBOARD
Pass a full setlist or chord chart to your bandmate using nothing but a hand gesture. Show a palm, make a fist, release. Done. No cables, no Bluetooth pairing screens, no typing a song title with sweaty fingers between sets. AirSync turns your whole band into one shared songbook, without anyone crowding around a single phone.

LIVE ROOM: LET THE AUDIENCE REQUEST SONGS DIRECTLY
Generate one permanent QR code for the night. Your audience scans it from their own phone browser, no app download needed, and sends requests straight to your Live Inbox in real time. You see every request the moment it lands, mid-set, without breaking stride. Tarius keeps 0% of any tips your audience sends along with a request.

OFFLINE SETLIST MANAGER, NO EXCEPTIONS
Build your setlist and reorder songs in seconds. Every chord chart, every lyric sheet, every setlist you create lives locally on your device, not in the cloud, not behind a Wi-Fi signal that drops the moment you walk into a basement venue. Your digital songbook opens the same way every time: instantly, offline, with nothing standing between you and your next song.

A STAGE TELEPROMPTER MADE FOR DARK ROOMS
Tarius runs a full-screen, OLED-black lyrics and chords teleprompter built specifically for low-light stages. Auto-scroll speed adjusts to your tempo. Bar Mode breaks each chord chart into blocks you can scan at a glance. The screen stays awake for the whole set, so you're never caught fumbling for your place mid-song.

EVERY STAGE TOOL A WORKING MUSICIAN ACTUALLY NEEDS
A chromatic tuner built to stay accurate over loud stage volume. A visual metronome that locks to your song's BPM. A gig timer that tracks your set length and the timing of every song within it. A capo calculator that gives you the right fret and chord shapes on the spot. And a one-tap setlist export for your Front of House engineer, so soundcheck stops being a guessing game.

BUILT AROUND ONE QUESTION
Will this help when it's dark, loud, and the show has to go on? That question decides what gets built into Tarius, and what doesn't. Your setlist, your chord charts, your lyrics, your teleprompter: all of it works offline, all the time, whether or not the venue has signal.
