# Twinkl vs Science Libs

The clearest difference is in-app purchases: Twinkl at none against Science Libs's 4. Twinkl also leads on ratings volume (2.5K vs 2). Science Libs's advantage is update cadence (every 9 days vs every 3 weeks) and iOS requirement (13.4 vs 16.0). On price, rating, ads and monetization model there is nothing between them.

Both are free to download. Science Libs sells 4 one-off in-app purchases. Twinkl asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.9 for Twinkl against 5.0 for Science Libs. That said, the two scores are not equally well evidenced: Twinkl has 2.5K ratings behind it against 2, so its average is the more settled of the two.

Twinkl ships an update every 3 weeks, Science Libs every 9 days. The most recent releases landed on September 26, 2026 and September 18, 2026 respectively.
