Verdict
The clearest difference is in-app purchases: Simplifythis at none against FieldServiceOS's 1. Simplifythis also leads on iOS requirement (16.4 vs 18.6). FieldServiceOS's advantage is update cadence (every 2 days vs every 3 months). On price, ads and device support there is nothing between them.
