The problem
Crossing time zones breaks medication routines. “Take at 8 am” stops making sense when 8 am in Dubai is 9:30 am in India. Time zone converters only show raw local time. They don’t tell you whether to keep home time, switch at once, or shift gradually. For time-sensitive medicines like insulin, birth control pills and seizure medication, a missed or doubled dose matters. Travellers often lack reliable internet abroad, so an online-only app fails exactly when it’s needed.
Who it’s for
Frequent flyers and business travellers Airline staff, who cross zones every week on irregular rosters Travellers on daily medication, especially chronic conditions
How it works
Set up once: add your medications, dose and schedule, plus your home city (for the home time zone). Plan a trip: enter your destination and days of stay. Get a shifted schedule: JetDose builds a day-by-day plan showing each dose in both local and home time, adjusted gradually where needed rather than snapped to the new clock. Go offline: the full plan is saved on the device, with reminders that work without internet. Return trip: the schedule shifts back home the same way.
Food and meal awareness
Log meals as you travel. New cuisines change how much and when you eat. For medicines that should be taken with food, or for insulin users, JetDose flags mismatches, for example “your dose is due but you haven’t logged a meal” or “this meal looks carb-heavy.” An LLM reads plain-language meal descriptions (such as “2 parathas with curd”) and gives a rough carb estimate. It informs, it doesn’t decide.
What makes it different
Body-aware, not clock-aware: it plans around dose intervals and meals, not just converted times. Offline-first: built for the moment you land without a SIM. Both clocks shown: every dose appears in local and home time, so nothing gets missed or doubled. Made for repeat crossings: airline crew can reuse it on every rotation.
Safety approach
JetDose never changes a dose amount and never says how much insulin to take. Meal and carb info is shown as a prompt to check glucose or follow your doctor’s travel plan. Each trip plan includes a “review with your doctor or pharmacist” note, and a printable summary you can show them.
