Verdict

The call

The clearest difference is in-app purchases: TCheckIn at none against Breadpad's 3. TCheckIn also leads on iOS requirement (12.0 vs 18.0). Breadpad's advantage is update cadence (fortnightly vs every 5 months) and chart position (#200 vs unranked). On price and ads there is nothing between them.
