Verdict
The clearest difference is rating: Mayer VMI at 5.0 against Trimble ProjectSight's 3.7. Mayer VMI also leads on monetization model (free vs freemium). Trimble ProjectSight's advantage is ratings volume (80 vs 1) and update cadence (every 2 weeks vs every 2 months). On price, ads, in-app purchases and device support there is nothing between them.
