# CELT vs IELTS Writing Tests

The clearest difference is in-app purchases: IELTS Writing Tests at none against CELT's 10. IELTS Writing Tests also leads on update cadence (every 2 months vs every 6 months) and iOS requirement (13.0 vs 15.5). CELT's advantage is ads (none vs shown). On price and device support there is nothing between them.

Both are free to download. CELT sells 10 one-off in-app purchases. IELTS Writing Tests asks for nothing beyond the download.

CELT ships an update every 6 months, IELTS Writing Tests every 2 months. The most recent releases landed on October 5, 2026 and October 4, 2026 respectively.
