Verdict
The clearest difference is price: GmSpeedPlus at Free against Tiltometer's $1.99. GmSpeedPlus also leads on rating (5.0 vs 3.6) and iOS requirement (16 vs 18.0). Tiltometer's advantage is update cadence (every 7 months vs every 30 months) and ratings volume (13 vs 2). On ads, in-app purchases and device support there is nothing between them.
