Verdict
The clearest difference is in-app purchases: PROSTART at none against Onform's 11. PROSTART also leads on rating (5.0 vs 4.8) and iOS requirement (8.0 vs 18.6). Onform's advantage is update cadence (every 6 days vs every 5 months) and ratings volume (8.6K vs 3). On price, ads and device support there is nothing between them.
