Read full description

Aquena is a water log that fits your day: one tap to record a glass, and that's it. A GOAL THAT STARTS WITH YOU Aquena suggests a daily goal worked out from general public references (EFSA and IOM). Would rather set it yourself? The manual goal is one tap away. MEASURES YOU RECOGNISE Ready measures, each with its own silhouette, always in order of volume. The four you use most sit on the home screen. Need a specific amount? Type it — that's free. TAPPED THE WRONG ONE? UNDO The wrong entry is the most common mistake in an app like this. So undo shows up right after every tap. YOUR HISTORY, DAY BY DAY A streak of days you hit the goal, a daily history, and counters that don't get lost. OPTIONAL LEADERBOARD A daily board, scored by percentage of your goal and capped at 100%. THREE LANGUAGES, TWO UNIT SYSTEMS English, Portuguese and Spanish. Millilitres and litres, or fluid ounces. ABOUT THE GOAL Aquena's calculation is an estimate based on general recommendations and does not replace professional assessment. Consult a doctor or dietitian to define your real hydration needs, especially in case of kidney, heart or liver conditions, pregnancy or use of medication.

Verdict

The call

The clearest difference is in-app purchases: HAIL™ at none against Aquena's 1. HAIL™ also leads on ads (none vs shown). Aquena's advantage is update cadence (every 2 days vs every 3 months) and device support (3 vs 1). On price and iOS requirement there is nothing between them.
