Verdict

The call

The clearest difference is ads: OWOer at none against MasterDex's shown. OWOer also leads on iOS requirement (10.0 vs 16.6). MasterDex's advantage is rating (4.8 vs 4.6) and update cadence (every 3 weeks vs every 2 months). On price, review sentiment, in-app purchases and monetization model there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

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

ReceptionRating · Positive reviews · Number of ratings

MasterDex holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: MasterDex has 1.7K ratings behind it against 130, so its average is the more settled of the two. Written reviews split almost evenly too, at 87% and 87% positive.

UpkeepUpdate frequency

OWOer ships an update every 2 months, MasterDex every 3 weeks. The most recent releases landed on October 8, 2026 and October 13, 2026 respectively.
