# Retro Flash vs Boulder Scoring

The clearest difference is rating: Retro Flash at 4.7 against Boulder Scoring's 4.2. Retro Flash also leads on ratings volume (226 vs 6) and device support (3 vs 1). Boulder Scoring's advantage is in-app purchases (none vs 8) and review sentiment (100% vs 83%). On price, update cadence, ads and iOS requirement there is nothing between them.

Both are free to download. Retro Flash sells 8 one-off in-app purchases. Boulder Scoring asks for nothing beyond the download.

Retro Flash holds the better App Store score, 4.7 against 4.2. That said, the two scores are not equally well evidenced: Retro Flash has 226 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 83% of Retro Flash's written reviews are positive against 100% of Boulder Scoring's, so the app with the better star average is not the one people write more warmly about.

Retro Flash ships an update every 3 weeks, Boulder Scoring every 2 weeks. The most recent releases landed on October 20, 2026 and October 16, 2026 respectively.
