Verdict
The clearest difference is rating: A at 3.0 against 天津地铁's 1.8. A also leads on update cadence (every 2 weeks vs every 5 weeks) and review sentiment (60% vs 51%). 天津地铁's advantage is ads (none vs shown) and ratings volume (23 vs 2). On price, in-app purchases, device support and iOS requirement there is nothing between them.
