Stalkie · Mobile Detective's advantage is ratings volume (2.9K vs 68) and iOS requirement (13.0 vs 18.0). On price, rating, update cadence and in-app purchases there is nothing between them.

Both are free to download. Stalkie · Mobile Detective sells 5 in-app purchases, starting at $5.99 per 7 days and Cold Case Trace sells 7 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.
