BetterSWE - Test your skills APP

Stop scrolling. Start leveling up.

BetterSWE helps software engineers and computer science students strengthen their fundamentals in just two minutes a day. Open the app, answer a real engineering question, review the explanation, and move on. No courses to schedule. No textbooks to finish.

HOW IT WORKS

Every day, you get a fresh engineering question. Answer it, read the explanation, and continue with your day. Get it wrong, and it returns later until you get it right.

Two minutes today beats a textbook you never open.

EIGHT ENGINEERING AREAS

Practice the topics that matter in interviews and on the job:

• Distributed Systems
• System Design
• Concurrency & Parallelism
• Networking
• Operating Systems
• Algorithms & Data Structures
• Security & Authentication
• Machine Learning & AI

BUILD YOUR RATING

Every answer adjusts your ELO-style rating. Climb through 14 engineering ranks, from Intern to Senior Fellow.

As you improve, watch your skill radar grow across all eight engineering areas.

KEEP YOUR STREAK

Show up each day to keep your streak growing. Miss a day, and it resets. Simple motivation to help you stay consistent.

LEARN FROM YOUR MISTAKES

Incorrect answers are added to your Error Set and resurface until you answer them correctly. Weak areas become opportunities to improve, and no question slips through the cracks.

MINI LESSONS WITH DIAGRAMS

Explore short lessons that break complex engineering concepts into clear, manageable explanations. Built-in diagrams help you see how systems, components, and ideas fit together without forcing you through walls of text.

TRACK YOUR PROGRESS

Your profile shows your rating history, activity heatmap, and skill breakdown across every engineering area.

See where you are improving, where you are strongest, and what you should practice next.

BUILT FOR BUSY ENGINEERS

BetterSWE is designed for people who want to improve but do not have time to commit to a traditional course.

Practice for two minutes on the train, in a waiting room, during a break, or before bed. Small sessions can still lead to meaningful progress.

Whether you are preparing for interviews, brushing up on fundamentals, or simply trying to stay sharp, BetterSWE meets you where you are.
