I am an English teacher who could not find one good place for all English study material — grammar, literature, MCQs, notes. Everything was scattered. YouTube videos were incomplete. Paid apps were expensive but shallow.

So I built English Master myself.

Built using Flutter. Backend on Firebase. Published on Google Play — May 2026.

What the app has:

• 50,000+ MCQs with explanations — topic wise
• 1,000+ chapter wise Master Notes
• 20,000+ Q&A for board and competitive exams
• 300+ downloadable study files — PDF, PPT, Word
• Full English Grammar — 60+ chapters, beginner to advanced
• English Literature — British, American, Indian, World
• Competitive exam prep — SSC, Bank PO, UPSC, UGC NET, Railways
• Dark mode, offline reading, progress tracking
• Supports ICSE, CBSE, NCERT, Cambridge boards
• 9 levels — Class 6 to Masters and PhD level

How I grew it:

Ran Google Ads UAC campaign myself — no agency, no team.

Results in 3 days:

700+ installs
29,600+ impressions
4,380+ clicks
Rs. 0.64 CPC
5-star rating — 12 reviews
300+ monthly active users
Active in-app purchase revenue

Handled everything — content creation, app development, ASO, keyword research, store listing, paid campaigns, Firebase analytics, user feedback.
