Verdict
The clearest difference is update cadence: Java面试(Voids) at every 10 days against LaunchBuddy's every 5 weeks. Java面试(Voids) also leads on rating (5.0 vs 4.8) and iOS requirement (17.0 vs 26.0). LaunchBuddy's advantage is ratings volume (107 vs 5) and review sentiment (85% vs 71%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Java面试(Voids) sells 1 one-off in-app purchase and LaunchBuddy sells 10 in-app purchases, starting at $2.99 per month. 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 4.8. That said, the two scores are not equally well evidenced: LaunchBuddy has 107 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 71% of Java面试(Voids)'s written reviews are positive against 85% of LaunchBuddy's, so the app with the better star average is not the one people write more warmly about.
Java面试(Voids) ships an update every 10 days, LaunchBuddy every 5 weeks. The most recent releases landed on October 2, 2026 and September 29, 2026 respectively.
