I'm Viktor - a software developer and DJ. After 10+ years behind the decks, I've learned that keeping your music library organized makes gigs run so much smoother.
When my go-to app got discontinued, I couldn't find anything that worked the way I needed - so I built my own.
What started as a simple weekend project has turned into a full toolkit I've been crafting in my free time. Tap metronome, real-time BPM detection, even a watchOS app for when you need it on the go. It's been a solo labor of love, built one feature at a time to solve the real problems I face behind the decks.
