TIDE — Water & Caffeine

TIDE turns hydration and caffeine into two numbers you can act on. One tap to log. Pick a preset with UP/DOWN, press START. Water, coffee, tea, energy drink, alcohol. No menus, no confirmation dialogs. A caffeine curve, not a counter. TIDE models how caffeine leaves your body over the day and shows the projected level at your bedtime. Instead of "you had 3 coffees", you get "you can still have 80 mg" - and a cutoff time after which a coffee is likely to still be with you when you try to sleep. Reminders only when they mean something. TIDE does not nudge you on a timer. It speaks up when the amount you still need would require drinking uncomfortably fast before bed, and when your caffeine cutoff is 30 minutes away. Three notifications a day at most. Fix mistakes on the watch. MENU undoes the last entry. A log page lists today's records so you can delete the wrong one. Your goal, from your profile. The daily target comes from the weight and sex in your Garmin profile, and the caffeine timing uses your configured sleep schedule. Optional sync. If you run your own server, set a URL and token in the app settings and TIDE will post your entries there. Left empty (the default), TIDE never uses the network and works entirely on the watch. Glance view included: today's total, pace, and how much caffeine you can still have. TIDE is a logging and planning tool. It does not diagnose, treat, or prevent any condition, and it is not a substitute for advice from a healthcare professional.

Fixed a bug where a trailing slash in the sync server URL setting caused all sync requests to fail with 404 (the app now strips it automatically).
