Verdict

The call

The clearest difference is ratings volume: MasterDex at 1.8K against GoDex's 1. MasterDex also leads on iOS requirement (16.6 vs 18.0). GoDex's advantage is rating (5.0 vs 4.8) and update cadence (every 8 days vs every 3 weeks). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. MasterDex sells 2 one-off in-app purchases and GoDex sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

GoDex holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: MasterDex has 1.8K ratings behind it against 1, so its average is the more settled of the two.

UpkeepUpdate frequency
