MyCaffeine helps you track your daily caffeine intake and understand how it affects your body — from your morning coffee to your last drink before bed. Log a drink in seconds, see exactly how much caffeine is in your system right now, and get a clear picture of how it builds up and fades throughout the day. Caffeine Tracking - See the current caffeine level in your body, updated in real time. - A live prediction graph shows your caffeine rising and falling across 24 hours, centred on now. - Caffeine now absorbs gradually rather than spiking instantly, so the curve better matches how you actually feel. - Forecast how much caffeine will still be in your system at bedtime. - A heads-up before you log a drink that would push you past your daily or bedtime limit. Water Tracking - Track your hydration alongside your caffeine, with a daily goal and a rolling 24-hour graph. - A hydration status label, from Dehydrated to Well Hydrated. - Water from every drink you log counts automatically. Apple Watch - Log drinks and water straight from your wrist. - Check your caffeine, hydration and daily total at a glance. - Complications for your watch face, kept in sync with your iPhone. Health Analysis - See how your caffeine lines up with your sleep, heart rate and activity, using data already in Apple Health. - Plain-language findings explain what your data actually shows. Trends & History - Track your intake, weekly patterns and bedtime caffeine levels over time. - Findings on every chart explain what you're looking at, in plain language. - Brand Ranking shows which brands you drink most, and what they add up to. - A calendar history with colour-coded daily intake at a glance. - Edit or delete any drink you've logged, from Today or History. Branded Drinks - Browse a growing catalogue from Coca-Cola, Starbucks, Red Bull and more — with serving sizes, nutrition and ingredients built in. - A redesigned Drinks tab, with search that ranks the closest matches first. - Your recent drinks are one tap away, remembering the serving size you last used. Custom Beverages - Create your own drinks based on caffeine quantity or concentration. - Custom drinks are saved under their own brand. - Decimal precision for more accurate tracking. Made For You - A metabolic calculator personalises your caffeine half-life and daily limits, instead of guessing. Widgets - Home Screen widgets showing your current level, drinks today, predicted bedtime level, and a 24-hour graph. - Lock Screen widgets to check your caffeine at a glance. - Water widgets for your Home Screen, Lock Screen and Apple Watch. - Quick Add shortcuts you choose, so your usuals are always one tap away.

Verdict
The clearest difference is rating: Simple Calorie Tracker at 5.0 against MyCaffeine's 3.6. Simple Calorie Tracker also leads on ads (none vs shown) and update cadence (every 2 days vs every 11 days). MyCaffeine's advantage is ratings volume (5 vs 1). On price, in-app purchases, monetization model and device support there is nothing between them.
