Verdict
The clearest difference is rating: Metaura at 3.4 against OTKAX's 2.0. Metaura also leads on ratings volume (12 vs 4). OTKAX's advantage is review sentiment (50% vs 22%) and monetization model (free vs ad-supported). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Metaura holds the better App Store score, 3.4 against 2.0. Both are backed by a comparable volume of ratings — 12 and 4 respectively.
