Verdict
The clearest difference is price: CallApp at Free against OpenSpam's $0.99. CallApp also leads on rating (4.6 vs 3.7) and ratings volume (715 vs 3). OpenSpam's advantage is in-app purchases (none vs 13) and ads (none vs shown). On review sentiment, update cadence, device support and iOS requirement there is nothing between them.
