## What is Otter?

Most people finish the day dehydrated without ever noticing. Otter makes it effortless to stay on track — log a drink in one tap and watch your animated progress ring fill toward your goal.

— KEY FEATURES —

• Animated circular progress ring — a smooth spring animation fills as you log each drink; a "Goal reached!" badge appears when you hit 100%
• Quick-add buttons — one tap for 250 ml, 500 ml, or 750 ml, the three most common drink sizes
• 8 bottle presets — from an Espresso Shot (30 ml) to a Jug (1 500 ml); swipe to remove any, or add your own custom bottle by name and capacity
• Custom entry — type any amount in ml or fl oz using the + button
• Smart daily goal — set your own target or let Otter suggest one based on your body weight (35 ml per kg)
• ml or fl oz — switch display units at any time in Settings; all values convert instantly
• 14-day history — an interactive bar chart shows your last two weeks at a glance; a goal reference line and per-day progress bars make streaks and gaps obvious
• Delete any entry — tap the trash icon on any log entry to correct a mistake
• Fully offline — your data never leaves your device; no account, no network, no ads

Otter stores everything privately in your device's local storage. There are no servers, no sign-in screens, and no tracking of any kind.

Start logging today and build the hydration streak your body deserves.
