# Innerstellar vs YUSEONG

The clearest difference is rating: YUSEONG at 5.0 against Innerstellar's 4.0. YUSEONG also leads on review sentiment (100% vs 62%) and update cadence (every 2 months vs every 6 months). Innerstellar's advantage is ads (none vs shown) and ratings volume (10 vs 1). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Innerstellar sells 1 one-off in-app purchase and YUSEONG sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

YUSEONG holds the better App Store score, 5.0 against 4.0. That said, the two scores are not equally well evidenced: Innerstellar has 10 ratings behind it against 1, so its average is the more settled of the two.
