Verdict
The clearest difference is in-app purchases: SeamStack at none against Bobbin's 3. SeamStack also leads on update cadence (daily vs every 6 weeks) and ratings volume (32 vs 6). Bobbin's advantage is ads (none vs shown). On price, rating, review sentiment and device support there is nothing between them.
