Caffeine Clock vs GhostDelta

Track your caffeine and sleep better. See exactly when today's coffee wears off. Caffeine Clock is a caffeine tracker that models absorption and half-life to estimate how much caffeine is in your system throughout the day. Log what you drink or eat, see how levels rise and fall, and plan your last cup so you can sleep with confidence. Accurate tracking with absorption rate Not just totals. Caffeine Clock models how quickly you absorb caffeine and how it declines (half-life), then estimates your level now and later. If you note how long you sipped that cappuccino, the curve updates accordingly. A clear, actionable dashboard An attractive graph shows your current level, projected decline, and how much caffeine you'll have at any time. Long-press to scrub the timeline and reveal exact values. At a glance, know whether you're in the clear - or whether another cup will push you past your comfort zone. Interactive Home Screen Widgets Monitor your stats without even opening the app. View your live caffeine curve and current mg count directly on your Home Screen. Need to log a refill? Use the quick-add widget to track your favorites with a single tap - keeping your data accurate with zero friction. Sleep-aware insights Set a target bedtime. If your projected level looks high by then, Caffeine Clock lets you know early, often before you even add a drink, so you can adjust your cut-off and protect tonight's sleep.

Private and fully offline No account, no signup. Your data stays on your device, with an option to transfer locally. Caffeine Clock works fully offline. Anytime, anywhere. Made for everyday routines Whether it's espresso at 8, tea at 2, or an energy drink before a workout, Caffeine Clock shows how today's choices affect tonight's sleep, so you can enjoy what you love without second-guessing it. How it works - Log a drink from the 200+ library or use the quick-add widget. - The app models absorption and half-life to estimate your level over time. - Watch the live caffeine curve and countdown on the dashboard or Home Screen. - Set a bedtime and get informed if you may still be "too caffeinated" by then. Why a dedicated caffeine tracker? Caffeine affects everyone differently. A general health app won't tell you when a 3 PM latte will still be in your system at 10 PM. Caffeine Clock focuses on one job: timing your intake for better days and better nights. Get started in minutes Install, finish the onboarding, log your first drink, and watch your caffeine curve come to life.

GhostDelta is a precision Apple Watch GPS recorder for outdoor sport: mountain biking, skiing and snowboarding, hiking, running, motorcycling, karting, boating and more. Record on your wrist. Analyse on your iPhone. Race yourself. Pick any stretch of trail, road or track and GhostDelta times every run against your own best, live and sector by sector, with the gap on your wrist while you're still moving. Ride a loop and every lap is timed the moment you cross the line. BEAT YOUR BEST Every run is timed automatically against your personal best, split into sectors and sub-sectors, with a live gap that tells you whether you're up or down before you reach the finish. Mark the section once as a Stage (a descent, a climb, a favourite run of corners) from any recording on your iPhone, or on the go: press the Action Button to start and stop a new Stage mid-ride. From then on GhostDelta spots the start by itself, and your Stage Book keeps every record, including runs you did before you created it. LAP TIMING Every lap is timed and ranked, with sector splits and a live gap to your best while you're still on track. Save any closed loop as a Circuit: a kart track, a lap of the park, a training loop. GhostDelta can even spot a loop by itself. Session bests and all-time bests are tracked automatically. FOLLOW ANY ROUTE Head for tomorrow's campsite without splitting your GPX. Import a route, trim it to the start and finish you want, and drop named waypoints along it: a campsite, a lunch stop, a summit. On your wrist, see the distance, climb and descent to the waypoint you choose or to the finish, the elevation profile ahead, and the next climb with its gain and gradient. Press the Action Button for a timeline of every waypoint ahead and behind you: tap one ahead to navigate to it, or one behind to see how far you've come since. Off-route warnings bring you back.
