Verdict
The clearest difference is price: HOTmate at Free against Pilot Anti's $2.99. HOTmate also leads on update cadence (every 3 weeks vs every 10 months). Pilot Anti's advantage is device support (3 vs 1) and iOS requirement (11.1 vs 17.0). On ads and in-app purchases there is nothing between them.
