Verdict
The clearest difference is ads: IMA Mobile at none against Librarian's shown. IMA Mobile also leads on monetization model (free vs ad-supported) and iOS requirement (13.0 vs 18.6). Librarian's advantage is update cadence (every 4 months vs every 16 months). On price, in-app purchases and device support there is nothing between them.
