Verdict
The clearest difference is price: Annotate at Free against Syncotron's $9.99. Annotate also leads on update cadence (every 4 days vs every 2 months) and ratings volume (7 vs 1). Syncotron's advantage is in-app purchases (none vs 1) and rating (5.0 vs 4.7). On ads, device support and iOS requirement there is nothing between them.
