# Bunpo vs Interslavic

The clearest difference is update cadence: Bunpo at every 9 days against Interslavic's every 13 months. Bunpo also leads on ratings volume (18K vs 4) and iOS requirement (16.0 vs 26.0). Interslavic's advantage is review sentiment (100% vs 72%). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Bunpo sells 7 in-app purchases, starting at $9.99 per month and Interslavic sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.9 for Bunpo against 4.8 for Interslavic. That said, the two scores are not equally well evidenced: Bunpo has 18K ratings behind it against 4, so its average is the more settled of the two.
