# KORAIL+ vs GCOO

The clearest difference is rating: GCOO at 2.9 against KORAIL+'s 2.4. GCOO also leads on review sentiment (46% vs 11%) and ratings volume (152 vs 11). KORAIL+'s advantage is monetization model (free vs free with in-app purchases) and update cadence (every 5 days vs fortnightly). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

GCOO holds the better App Store score, 2.9 against 2.4. That said, the two scores are not equally well evidenced: GCOO has 152 ratings behind it against 11, so its average is the more settled of the two. Written reviews point the same way: 11% of KORAIL+'s written reviews are positive against 46% of GCOO's.

KORAIL+ ships an update every 5 days, GCOO fortnightly. The most recent releases landed on October 17, 2026 and October 18, 2026 respectively.
