Watch every query work, one row at a time. Then try it yourself: tap the blocks or type the query. When you’re ready, take on a new interview-style challenge every day.
Learn SQL in five minutes a day, on your phone. Every lesson teaches one idea, then you practice it straight away — tap-based exercises, nothing to type, nothing to set up.
Every day there's also one real SQL interview question, from companies like Airbnb and Amazon. Free for everyone.
WHAT YOU'LL LEARN
- SELECT, FROM, WHERE — the building blocks of every SQL query
- Filtering, sorting, and grouping data
- JOINs — combining data from multiple tables
- Aggregate functions like COUNT, SUM, AVG
- Subqueries and more advanced concepts
FEATURES
- A daily SQL interview question from real companies
- 8 exercise types including fill-in-the-blank, query builder, and debug challenges
- AI tutor that explains concepts and gives hints without giving away the answer
- Streak tracking to build a daily habit: lessons and the daily question both count
- Progress saved across devices

This is a great app. I wish I had this when I was first getting into IT, because while I'm not a DBA, I do often pull data from SQL databases.
Developer Response
Thank you! Pulling data without being a DBA is exactly the situation I had in mind while building this. Hope it keeps being useful.
MintQuery 1.10
• New lessons: every lesson is now a set of short cards you tap through, with step-by-step walks through the rows and animated JOINs.
• Type it: write your answer as a query instead of tapping blocks. Typed answers earn extra mints, and a typo (like a misspelled column) gets a hint instead of costing you an attempt.
• Practice more: extra practice rounds after a lesson, plus mixed practice across the modules you’ve finished.
• Home is now Learn, with a course switch. Real-World SQL is coming soon: tap “Tell me when it’s out” to hear first.
• Your certificate can now be downloaded as a PDF and added to your LinkedIn profile.
• Clearer hints and explanations across the course, and lots of smaller fixes.
