Verdict
The clearest difference is in-app purchases: HydraFill at none against Water tracker's 3. HydraFill also leads on update cadence (every 2 days vs every 3 weeks) and iOS requirement (15.0 vs 17.0). Water tracker's advantage is ads (none vs shown). On price and device support there is nothing between them.
