CentWatch is a clock and stopwatch that can display time in cents (hundredths of a minute). This is useful in Time-Speed-Distance (TSD) rally competition. The user may select between white text on black or black text on white, as appropriate for ambient lighting conditions. The user may also adjust the displayed time to be different from the time reported by iOS and match event time. In addition to displaying time in hours:minutes.cents format, time may also be displayed in standard hours:minutes:seconds format. Caveat: CentWatch bases the time value on the iOS system time. This can drift and shift during the day. Future versions of CentWatch will try to work around this.

Verdict
The clearest difference is price: CentWatch at Free against Richta's $9.99. CentWatch also leads on ratings volume (4 vs 1) and iOS requirement (9.0 vs 12.0). Richta's advantage is rating (5.0 vs 4.3) and update cadence (every 5 months vs every 49 months). On ads, in-app purchases and device support there is nothing between them.
