Build Stellar
Apps.
We design and engineer AI-powered mobile products that feel obvious, calm, and a little bit cosmic. A small studio, with high standards.
Three products,
obsessively made.
Every pixel, every transition, every line of copy — held to a standard we'd be proud to ship at Apple.
Split Any Song Into Stems.
Split any song into vocals, drums, bass, guitar & more with studio-grade AI — remix, mute, remaster, or create instant karaoke, right on your phone.
The Tempo Trainer.
The metronome that trains your ear, not just your click. Tap tempo, odd meters, polyrhythms, and rhythm games — built for musicians who take time seriously.
A daily ayah, every morning.
Build a daily Qur'an habit, one ayah at a time. Swipe through verses, track your streak, get gentle reminders, and read in 24 languages.
A studio of three, building software for the next billion creators.
Stellup is an independent app studio crafting tools at the intersection of AI, music, and daily ritual. We work in small teams, ship in long arcs, and treat our apps like instruments — tuned obsessively until they sing.
We are remote-first, design-led, and quietly ambitious. Our work is used by musicians in Lagos, students in Istanbul, and producers in Brooklyn.
