Verdict
The clearest difference is review sentiment: Robot72 at 100% against ASIAIR's 52%. Robot72 also leads on rating (4.9 vs 3.9) and update cadence (every 3 weeks vs every 2 months). ASIAIR's advantage is in-app purchases (none vs 2) and ads (none vs shown). On price and device support there is nothing between them.
