Verdict
The clearest difference is monetization model: Java面试(Voids) at free with in-app purchases against CodeMaster's subscription. Java面试(Voids) also leads on rating (5.0 vs 4.6) and review sentiment (71% vs 44%). CodeMaster's advantage is ratings volume (140 vs 5). On price, ads, in-app purchases and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. CodeMaster sells 3 in-app purchases, starting at $1.99 per 7 days 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 4.6. That said, the two scores are not equally well evidenced: CodeMaster has 140 ratings behind it against 5, so its average is the more settled of the two. Written reviews point the same way: 44% of CodeMaster's written reviews are positive against 71% of Java面试(Voids)'s.
CodeMaster ships an update monthly, Java面试(Voids) every 10 days. Both last shipped on October 2, 2026.
