Verdict
The clearest difference is ads: HaasService at none against Thread Calculator's shown. HaasService also leads on update cadence (every 2 weeks vs every 18 months) and monetization model (free vs ad-supported). Thread Calculator's advantage is review sentiment (33% vs 0%). On price, in-app purchases, device support and iOS requirement there is nothing between them.
