MCRB Labs started as a shared frustration with productivity apps that ask for more effort than they save. We're building the opposite: tools that watch, quietly, and tell you the truth.
MCRB Labs is run by two A-level students, handling both the software and the hardware side ourselves.
Currently studying for A-levels alongside building MCRB Labs. Focused on product direction and the systems that hold Focus and the USB hub together.
Currently studying for A-levels alongside building MCRB Labs. Focused on engineering — from the Focus app's tracking logic to the hardware side of the USB hub.
These shape what we build and what we say no to.
If a tool needs daily upkeep to stay useful, it's not done yet. Everything we build should work without being managed.
Your activity data is yours. We build local-first, and we're explicit any time that ever changes.
No streak guilt-trips, no manipulative notifications. A number should tell you the truth, not sell you a subscription.
Still early — this timeline will keep growing.
Frustrated with productivity apps that required more manual tracking than the focus they were meant to save, we started sketching what an automatic version could look like.
Started building the Focus app for Windows — foreground-window tracking, classification rules, and the scoring system — alongside A-levels.
Formed MCRB Labs and started designing the Focus USB Hub — hardware that reacts to your Focus Score directly. Both projects are in active development.
