Verdict
The clearest difference is in-app purchases: Quadrant at none against Bird Tracker's 1. Quadrant also leads on ads (none vs shown) and iOS requirement (17.0 vs 26.1). Bird Tracker's advantage is update cadence (every 3 days vs every 10 days). On price, review sentiment and device support there is nothing between them.
