Verdict
The clearest difference is in-app purchases: Infraway at none against The Stack System's 8. Infraway also leads on device support (3 vs 1). The Stack System's advantage is ads (none vs shown) and ratings volume (7K vs 14). On price, rating, update cadence and iOS requirement there is nothing between them.
