  • Zonal app showing accurate time zone detection while traveling

    Sound familiar?

    You land in Tokyo after a red-eye from San Francisco. You open your calorie tracker to add your meal on the plane — and it says you didn't eat at all yesterday. An entire day logged that doesn't reflect reality.

    Or you're in the middle of a week long around the world business trip. Your suggested bedtime makes no sense at all. It doesn't make sense in your home time nor your current location.

    Worst of all: you take daily medication and rely on timed reminders. You fly from New York to Paris, and your reminder fires at 8 AM because it doesn't notice time zone shifts. You take your meds 6 hours late.

    Every time related app on your phone depends on you to convert the times, ignore the discontinuous graphs, or decipher their interpretation of how time zone shifts should work. No longer.

    How It Works

    Without Zonal

    • Sleep score and bedtime make no sense
    • Calorie trackers don't reflect reality
    • Medication reminders float with time zone regardless
    • Weekly health summaries are scattered with time zone artifacts
    • Error prone math to make future alarms in other time zones

    With Zonal

    • Sleep score and bedtime are under your control
    • Easy diet tracking while on the road
    • Medication reminders adjust to local time or don't, your choice
    • Your health data just works, wherever you are
    • Alarms in any time zone with no confusion
