# Easy Grading Calculator vs BlueBird Alerts

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).

Both are free to download. Easy Grading Calculator sells 5 one-off in-app purchases. BlueBird Alerts asks for nothing beyond the download.

BlueBird Alerts holds the better App Store score, 5.0 against 4.8.

Easy Grading Calculator ships an update every 13 months, BlueBird Alerts every 2 days. The most recent releases landed on October 30, 2026 and October 24, 2026 respectively.
