Quick Comparison Table

1. Caffeine Tracker: Sleep Better

Best for: Anyone who wants a clear, science-backed cutoff time so caffeine never steals their sleep.

This app does more than just count milligrams. It calculates when caffeine will be fully out of your body using your weight, sleep target, and the standard half-life model. You get a daily “stop by” recommendation that shifts with your bedtime. No more guessing if that 4 p.m. energy drink will keep you up.

The visual timeline shows your caffeine level dropping hour by hour, from peak absorption all the way to zero. You can log coffee, tea, energy drinks, soda, and more from a curated library, then edit any entry’s time and watch the body math update instantly. Everything runs on your device. No accounts, no data collection, no ads.

• Personalized stop-by cutoff that shifts with your sleep schedule
• Live caffeine curve that runs until your bedtime
• Daily limit based on FDA guidelines, your age, and sensitivity

stimhead is built for energy drink collectors. It recognizes over 445 drinks across 42 brands when you scan a barcode, pulling in the caffeine content right away. You can track your intake and also build a digital collection of the cans you’ve tried, which adds a light game-like feel. Logging is fast. Point, scan, and you’re done.

3. CaffeInMe - Caffeine Tracker (Android)

Best for: Android users who want a straightforward, sync-friendly tracker across devices.

4. HiCoffee - Caffeine Tracker (iOS)

Best for: Visual learners who want to see caffeine metabolism on a chart.

HiCoffee shows your caffeine metabolism as a graph. Log a drink and you’ll see a timeline of how long caffeine stays in your system and when you’ll be back to baseline. If you learn better by seeing a curve than reading a number, this one clicks.

5. Caffeine Clock: Track Caffeine (Android)

Best for: Data nerds who want a live caffeine level curve and countdown.

Caffeine Clock gives you a live estimate of how much caffeine is still in your body. It models absorption and half-life to show a curve and a countdown timer that both update in real time. Watching the line drop helps you decide if grabbing another can is a good idea or a bad one for sleep.

6. Energeia Tracker (iOS)

Best for: Minimalists who only track energy drinks and want local privacy.

Energeia Tracker is laser-focused on energy drinks. It logs only caffeine and sugar from what you drink, nothing else. All data stays on your phone, so it’s private and snappy. Open the app, log a can, close it. No clutter.

7. LessCoffee: Caffeine Tracker (Android)

Best for: People who want a lightweight app to stay under a healthy limit without fuss.

LessCoffee keeps things minimal. Log your drinks quickly and you’ll see a simple bar that shows if you’re below a healthy daily limit. It’s not about detailed half-life charts. It’s about staying in the green zone. One look tells you if you’re safe or overdoing it.

8. Caffeine Tracker: Alyx (iOS)

Best for: Apple Health users who want privacy and iCloud sync.

Alyx writes your caffeine data straight into Apple Health and syncs privately through iCloud, with no extra accounts. It gives customized insights on when you’ll be caffeine-free and how intake patterns affect sleep, all while keeping your log tucked alongside other wellness metrics. If you already live in the Health app, this fits neatly.

9. CaffeTrack - Caffeine Tracker (Android)

Best for: Real-time tracking fans who want precise half-life calculations for popular brands.

CaffeTrack uses brand-specific half-life models for drinks like Red Bull, Monster, and different coffees. Pick your brand, log a can, and the app shows a precise countdown of how much caffeine is still in your body. It’s built for people who want to see the numbers drop in real time.

How We Picked These Apps

We only considered apps focused on caffeine and energy drink tracking, not generic diet apps. Accuracy came first. We dug into how each app calculated half-life and cutoff times. Fast logging was a must, so barcode scanning and one-tap presets got bonus points. We made sure to include both iOS and Android options, and we rewarded apps that store data locally for privacy. Above all, we chose apps that turn raw numbers into clear, useful advice instead of dumping a spreadsheet on you.

Frequently Asked Questions

How do these apps calculate when caffeine leaves my system?

They start with a standard caffeine half-life of about 5 hours and refine it using your weight, sleep target, or personal metabolism factors. The result is a science-backed approximation, not a lab test, but far better than guessing.

Can I track sugar and other ingredients with these trackers?

A few do. Energeia Tracker and stimhead track sugar as well as caffeine. Most energy drink trackers stick to caffeine, but you might find extras like taurine or total can sugar buried in the settings.

Are these apps free?

Most are free for basic tracking, with paid upgrades for extras like detailed charts, syncing, or longer history. You can usually do daily logging for nothing, but if you want the advanced features, check the in-app purchases first.

The Verdict

Caffeine Tracker: Sleep Better is our top pick for most people because it answers the one question that matters: “When should I stop?” Other apps can scan barcodes, generate charts, or sync with Apple Health, but they don’t give you a personalized cutoff time that actually protects your sleep. If you’re tired of guessing and want to enjoy caffeine without wrecking your night, start here.
