# DigitZ vs Once Upon a Galaxy

The clearest difference is price: Once Upon a Galaxy at Free against DigitZ's $0.99. Once Upon a Galaxy also leads on rating (4.8 vs 4.0) and update cadence (fortnightly vs every 38 months). DigitZ's advantage is in-app purchases (none vs 50) and review sentiment (100% vs 83%). On ads and device support there is nothing between them.

Once Upon a Galaxy is free to download; DigitZ costs $0.99 up front. Once Upon a Galaxy sells 44 one-off in-app purchases. DigitZ asks for nothing beyond the download.

Once Upon a Galaxy holds the better App Store score, 4.8 against 4.0. That said, the two scores are not equally well evidenced: Once Upon a Galaxy has 1.4K ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 100% of DigitZ's written reviews are positive against 83% of Once Upon a Galaxy's, so the app with the better star average is not the one people write more warmly about.

DigitZ ships an update every 38 months, Once Upon a Galaxy fortnightly. The most recent releases landed on October 12, 2026 and October 30, 2026 respectively.
