Verdict

The call

The clearest difference is review sentiment: PlanForm at 100% against CADraw's 50%. PlanForm also leads on rating (5.0 vs 2.9) and monetization model (free vs free with in-app purchases). CADraw's advantage is ratings volume (10 vs 2) and iOS requirement (13.0 vs 15.0). On price, update cadence, ads and in-app purchases there is nothing between them.
