Lessons so simple you'll wonder if that's allowed. That's the point.
The truth about getting promoted
You are 1–2 skills away from your next role.
But nobody tells you which ones they are.
And 40-hour courses were never the answer.
What you need is five minutes that show up in tomorrow’s meeting.
So we built
a different way.
Great fit — 6 gaps to close.
It starts by reading your resume — every role, every win.
Then it maps your skills against the role you’re dreaming about — not a generic ladder.
And tells you, honestly, how close you are.
Then it builds the 12-week plan to close the distance.
Our promise
Complexity is how courses justify 40 hours. Simplicity is how skills actually stick.
Why it sticks
Built on learning science.Not vibes.
Every mechanic in GapFix maps to a well-replicated finding from memory and habit research.
Most of what you learn is gone in a week.
Since Ebbinghaus, memory research has shown the same curve: without review, new knowledge fades within days. Reviews at expanding intervals flatten it.
That's why GapFix ends every lesson and booster with a check that seeds a review queue — and why the 2-minute Daily Practice asks you again right when you'd otherwise forget.
Spaced repetition
Reviews at expanding intervals — a day, three, a week, longer — beat cramming for durable memory. The 2-minute Daily Practice runs on exactly this schedule, tuned to how well you remember.

Retrieval practice
Answering strengthens memory more than re-reading. Every review is question-first, and every lesson item ends with an applied scenario check — never definition recall.

Learning by doing
Half of every session is you doing, not reading: scenario decisions, rewrites with feedback on your own words, roleplay, and one real-world action to finish today.
Transfer research — practice beats exposure
Habit formation
New habits take roughly 66 days to become automatic. ~15-minute days, streaks with shields that forgive real life, and a 12-week arc are sized for that.
Lally et al. — how habits form
We're new, so you won't see invented outcome stats here. When we publish numbers, they'll be real. Until then — this is the research we build on, and you can read exactly how each finding shows up in the app.

Built for real work, not exams
For the moment you're actually in.
Every lesson ends with one real action you'll take at work this week. Millions of people hit these moments every day — now there's a five-minute way to be ready.
