Verdict

The call

The clearest difference is in-app purchases: Hitienx Ring Sizer at none against USB Sharp's 6. Hitienx Ring Sizer also leads on ads (none vs shown) and update cadence (every 4 days vs every 3 weeks). USB Sharp's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 17.0). On price there is nothing between them.
