SkillFlow tracks your skill across 10 topics and picks the right problem every time.
01 · Where most people get stuck
Stuck on new problems.
No sense of progress.
Always the same topics.
The problem isn't effort. It's that you're choosing your own problems, biased toward what feels comfortable, blind to where you actually need work.
02 · The difference
Without SkillFlow
Open LeetCode. Browse for 15 minutes.
Pick something familiar. Feel productive.
Finish. No idea if you improved.
Repeat. Avoid the hard topics.
With SkillFlow
Open SkillFlow. One question, chosen for you.
It's in your weakest topic, at your level.
Submit. Skill score updates instantly.
Tomorrow's question recalibrates.

05 · Honest answers
Q.01
How is this different from LeetCode?
LeetCode is a library. SkillFlow is a coach. Their job is to give you 3,000 problems and let you choose. Ours is to pick the right one for you, and get out of the way.
Q.02
Does my skill score drop if I fail?
Yes. Skill score moves both ways: up when you solve, down when you don't. That's why it's a real signal of where you stand, not a vanity metric. We don't recommend skipping for that reason.
Q.03
What happens if I miss a day?
Nothing punishing. Your skill score stays where it was. Streaks exist for motivation, but missing one doesn't reset progress. SkillFlow is built for the weeks before an interview, not as a forever habit.
Q.04
Which languages do you support?
Python, Java, and C++. You pick during onboarding and can switch any time on the problem page.
Q.05
Is it really free?
Yes. Completely free. No credit card, no trial limits. We may add paid tiers later for things like company-specific question packs and mock interview reviews.
Q.06
How is the question picked for me?
We look at your weakest topic, your current proficiency, and which problems you haven't seen yet. The next question lives where the lift is largest: slightly above your level, in the area you've been avoiding.
