CaffeineTap
Log caffeine in one tap and see how many mg you can still drink today - with a widget and cutoff reminder.
Overview
CaffeineTap is a lightweight caffeine tracker built to answer one question fast: how much caffeine can I still drink today? Tap coffee, espresso, tea, cola, or an energy drink and the app updates your daily total, your remaining amount against your personal limit, and a simple pace status.
It deliberately skips what heavier caffeine apps pile on - no accounts, no complicated charts, no HealthKit, no half-life math, no sleep predictions. Just quick logging, a seven-day history, and a small Home Screen widget showing today's remaining caffeine at a glance.
A single optional notification, the Cutoff Reminder, nudges you at the time you choose so you can pause before drinking caffeine late in the day.
Who It Is For
- Coffee drinkers who want to stay under a daily caffeine limit without effort
- People trying to cut back on afternoon caffeine for better evenings
- Energy drink and tea drinkers who lose track of how much they've had
- Anyone who abandoned heavyweight caffeine apps and just wants a quick log
- People who want their remaining caffeine visible on the Home Screen
Main Features
- One-tap logging with presets: coffee (95 mg), espresso (65 mg), black tea (45 mg), green tea (30 mg), energy drinks (80/160 mg), cola (40 mg)
- Custom amount entry for anything else
- Personal daily limit in mg, with today's total, remaining amount, and a pace status (Good pace, Moderate, Near your limit, Over your daily limit)
- Seven-day history grouped by day, with entry deletion
- Small Home Screen widget showing today's remaining caffeine, or 'Over limit' when exceeded
- Cutoff Reminder - a single local notification at the time you set
- Local storage only; no account, no HealthKit
How to Use
- Set your personal daily caffeine limit in Settings.

- Check the home screen for today's total, how many mg you have left, and your pace status.
- Add the small widget to your Home Screen to see remaining caffeine without opening the app.
- Optionally enable the Cutoff Reminder in Settings to get a nudge at your chosen time.
- Review the last seven days in History and delete entries if you mis-tapped.

The Cutoff Reminder is a local notification, and permission is requested only if you enable it.
