Verdict

The call

The clearest difference is in-app purchases: 8Synk at none against GPS Speedometer's 11. 8Synk also leads on ads (none vs shown) and update cadence (every 3 days vs every 2 months). GPS Speedometer's advantage is device support (4 vs 1) and iOS requirement (15.0 vs 18.6). On price there is nothing between them.
