Verdict
The clearest difference is rating: Java面试(Voids) at 5.0 against Golang & SQL's 4.5. Java面试(Voids) also leads on update cadence (every 10 days vs every 3 months). Golang & SQL's advantage is ratings volume (29 vs 5). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Golang & SQL sells 5 one-off in-app purchases and Java面试(Voids) sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Java面试(Voids) holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Golang & SQL has 29 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 76% of Golang & SQL's written reviews are positive against 71% of Java面试(Voids)'s, so the app with the better star average is not the one people write more warmly about.
Golang & SQL ships an update every 3 months, Java面试(Voids) every 10 days. The most recent releases landed on September 23, 2026 and September 14, 2026 respectively.
