Verdict

The call

The clearest difference is ads: Tempo at none against Speedometer's shown. Tempo also leads on update cadence (every 6 weeks vs every 43 months). Speedometer's advantage is iOS requirement (12.0 vs 17.0). On price, in-app purchases and device support there is nothing between them.
