North Star Labs is a small, independent studio making iOS apps that help people spend less time scrolling and more time on what matters. Our flagship app is ScrollToll.
Study to unlock - for iOS
ScrollToll locks distracting apps like Instagram and TikTok behind a quick exam question. Answer it correctly and you earn a few minutes to scroll. When the time is up, the lock comes back. It turns the urge to open an app into a moment of practice.
Built for premed and MCAT students who want to swap a bit of doomscrolling for spaced, low-effort review, every time they reach for their phone.
ScrollToll catches the moment and puts a question in front of you instead.
Get it right and the app unlocks for a short, set window.
When your time runs out, the lock returns, so the habit stays in check.
We build behavior-change tools that put a small, useful friction between you and the apps that pull your attention.
Our apps are built on Apple's native frameworks. Screen Time controls run on your device, and we keep data collection minimal.
A small studio shipping a tight set of iOS apps. We would rather do one thing well than ten things halfway.
