Verdict
The clearest difference is in-app purchases: hamsfi at none against AquaPiscium's 7. hamsfi also leads on ads (none vs shown). AquaPiscium's advantage is update cadence (every 6 days vs every 2 months) and iOS requirement (15.6 vs 17.6). On price and device support there is nothing between them.
