Verdict

The call

The Document Converter and EpubLab both sit at 4.7 stars, but that hides the real split: 100% of EpubLab's written reviews are positive against 36% of The Document Converter's. EpubLab also leads on update cadence (fortnightly vs every 5 months). The Document Converter's advantage is ads (none vs shown) and ratings volume (6K vs 3). On price, rating, in-app purchases and monetization model there is nothing between them.
