What it is
What it does
Fumble is a macOS menu-bar app that watches you type and gives lessons based on which keys are costing you time.
Problem
Can't improve what you don't measure.
Competition
The niche may be somewhat saturated with existing typing improvement tools, but Fumble focuses on personalized key metrics.
Weaknesses
Warning: early days. Not everything has been tested in the wild yet.
What could be built instead
Opportunity
Develop a smarter method for word choice in weak-spot drills.
Vertical niche
Yes, it could be made into a vertical SaaS for typing improvement.
MVP
The smallest MVP would be a tool that tracks key presses and identifies weak keys.
Differentiation
Fumble uniquely ranks weak keys by time lost rather than just speed.
AI opportunity
Using AI to optimize the selection of words for weak spots based on user data could add significant value.

Evidence
I love keybr, but it only sees the ten minutes a day I spend on keybr, not the ten hours I spend typing elsewhere.
The goal isn't to practice the slowest keys, it's to raise your WPM.
it records physical keycodes and timings not characters.
