Verdict
The clearest difference is rating: Annotable at 4.6 against Annotium's 4.0. Annotable also leads on ads (none vs shown) and review sentiment (75% vs 44%). Annotium's advantage is update cadence (daily vs every 2 months). On price, in-app purchases, monetization model and device support there is nothing between them.
