SipNest is a calm offline hydration tracker for people who want a simple record of what they drink each day. Set a daily water goal, add 250 ml or 500 ml with one tap, save favorite amounts, or enter a custom drink with type, time, and notes.
Your Today view shows progress, remaining intake, quick actions, and an editable timeline. Insights turn saved drinks into daily totals, weekly trends, and streaks so you can see whether your routine is staying steady. Preferences let you switch units, tune your goal, edit reminder wording, choose week start text, export JSON, import JSON, and reset local data.
SipNest stores hydration history on your device with AsyncStorage and works without accounts or network access. It is built for practical daily use: clear validation, empty states, editable entries, delete confirmations, and portable local data tools.
