Every rockstar needs a roadie. Korena is the toolkit that lives in your case: a chromatic tuner, a metronome, a practice timer, chord and scale references, gig checklists — and a Gear Locker that documents what you own before you ever need the proof. THE GEAR LOCKER Photograph an instrument and Korena reads the make, model and serial number straight off the headstock, prices it against the current market, and keeps the photos, receipts and paperwork together in one record. It runs a documentation check so you can see what a claim would ask for and what you are missing — long before anybody asks. Everything stays on your device. TUNER Chromatic tuning with a cents readout, alternate tunings, and adjustable calibration. Accurate enough for a restring, fast enough between songs. METRONOME Tap tempo, subdivisions, accent patterns and five click voices. Loud enough to hear over an amp. CHORDS, SCALES AND MODES Every shape for both hands. Play a scale and Korena listens, tells you which notes landed and which you missed, and keeps the ones you got right lit up as you go. Positions are numbered the way guitarists actually count them. GEAR DOCTOR Photograph the problem and describe the noise. Korena works out what it likely is and roughly what it costs to fix, so you walk into the shop knowing what you are talking about. It does not diagnose amplifiers, PA speakers, mixers or anything else that plugs into the wall — that work belongs to a qualified technician. PRACTICE AND PERFORMANCE A practice timer with sessions and streaks. Gig checklists per band or venue, so the cable you always forget is on the list. Reminders that make time for music. THE STORE 87,000 instruments in stock, searchable by describing the sound you are chasing rather than the model number you do not know. Save the strings, picks, reeds and sticks you actually use and reorder the lot in a tap. Browsing needs no account, and guest checkout works. Free. No account needed to browse, tune, or use the toolkit. Korena is made by Guitar Center. Value estimates are automated market guides, not appraisals. Korena does not provide, arrange or determine insurance, and documentation indicators are not a statement that you are adequately insured. Confirm coverage with your carrier. ## Key features - Chromatic tuner with alternate tunings - Metronome with tap tempo and subdivisions - Practice timer with sessions and streaks - Chord and scale references with playable feedback - Gear Locker for instrument documentation and market value - Gig checklists and reminders - Instrument search by sound description ## Is Korena safe?
