Verdict
The clearest difference is in-app purchases: TH at none against Timegrapher's 1. TH also leads on update cadence (every 2 months vs every 8 months) and iOS requirement (12.2 vs 16.0). Timegrapher's advantage is ratings volume (46 vs 10). On price, rating, review sentiment and ads there is nothing between them.
