Verdict

The call

The clearest difference is in-app purchases: BlueBird Alerts at none against Easy Grading Calculator's 5. BlueBird Alerts also leads on ads (none vs shown) and update cadence (every 2 days vs every 13 months). Easy Grading Calculator's advantage is ratings volume (50 vs 2). On price, review sentiment, device support and iOS requirement there is nothing between them.
