Verdict

The call

The clearest difference is ads: WattGuru at none against FlipClock's shown. WattGuru also leads on update cadence (fortnightly vs every 19 months). FlipClock's advantage is iOS requirement (13.0 vs 17.6). On price, in-app purchases and device support there is nothing between them.
