Verdict

The call

The clearest difference is monetization model: iWriter Pro at free against 24's paid. iWriter Pro also leads on ratings volume (132 vs 2). 24's advantage is rating (5.0 vs 4.7) and iOS requirement (18.5 vs 26). On price, ads, in-app purchases and chart position there is nothing between them.
