# Retro Tuner vs K1047

The clearest difference is price: K1047 at Free against Retro Tuner's $2.99. K1047 also leads on rating (4.8 vs 3.5) and ratings volume (122 vs 2). Retro Tuner's advantage is ads (none vs shown) and review sentiment (63% vs 50%). On in-app purchases and device support there is nothing between them.

K1047 is free to download; Retro Tuner costs $2.99 up front. Neither carries in-app purchases, so what you see is what you pay.

K1047 holds the better App Store score, 4.8 against 3.5. That said, the two scores are not equally well evidenced: K1047 has 122 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 63% of Retro Tuner's written reviews are positive against 50% of K1047's, so the app with the better star average is not the one people write more warmly about.

Retro Tuner ships an update every 9 months, K1047 every 5 months. The most recent releases landed on October 23, 2026 and October 24, 2026 respectively.
