Verdict
The clearest difference is monetization model: 时间流 at free against Calflow's free with in-app purchases. 时间流 also leads on update cadence (every 3 days vs every 10 days). Calflow's advantage is ratings volume (131 vs 4). On price, rating, ads and in-app purchases there is nothing between them.

On the App Store both sit at effectively the same score — 4.9 for Calflow against 5.0 for 时间流. That said, the two scores are not equally well evidenced: Calflow has 131 ratings behind it against 4, so its average is the more settled of the two.
