Verdict
The clearest difference is in-app purchases: KeyHelper at none against BimmerCode's 2. KeyHelper also leads on update cadence (every 4 days vs every 2 months) and rating (5.0 vs 4.7). BimmerCode's advantage is ads (none vs shown) and ratings volume (22K vs 1). On price and device support there is nothing between them.
