Verdict

The call

The clearest difference is price: Chess.com at Free against HIARCS Chess's $9.99. Chess.com also leads on update cadence (weekly vs every 3 months) and ratings volume (827K vs 199). HIARCS Chess's advantage is in-app purchases (none vs 12) and ads (none vs shown). On rating and device support there is nothing between them.
