About this app
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 Amazon, Google and Microsoft. 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
WHO IT'S FOR
MintQuery is for beginners learning SQL for the first time, career switchers moving into data analytics, analysts refreshing skills they haven't used in a while, and anyone preparing for SQL interview questions. Practice writing queries, filtering data, joining tables, and debugging SQL — all from your phone, no laptop required.
WHY MINTQUERY
No hearts. No energy timers. No ads. No waiting three hours to continue a lesson. Make mistakes freely — that's how you learn.
MintQuery is free to use, including the daily question and the first three modules. Premium unlocks all nine modules and unlimited AI tutor help, available as a monthly or annual auto-renewing subscription.
