# Tesdopi vs Rocket English

The clearest difference is update cadence: Tesdopi at every 3 weeks against Rocket English's every 12 months. Tesdopi also leads on ratings volume (60 vs 1). Rocket English's advantage is rating (5.0 vs 4.6). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Tesdopi sells 14 one-off in-app purchases and Rocket English sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Rocket English holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Tesdopi has 60 ratings behind it against 1, so its average is the more settled of the two.

Tesdopi ships an update every 3 weeks, Rocket English every 12 months. Both last shipped on October 24, 2026.
