About
Tell Gwhen what you want to do. Gwhen tells you when to do it.
Gwhen is not another weather app. It answers one question: when is the best time to do the thing you care about — based on the conditions that matter to you.
Add your activities — cycling, running, tennis, a stroller walk, and more. Gwhen scores the day, picks the best opening, and shows you exactly when to go.
WHAT YOU GET
• A clear recommended time window — the hero on every screen
• Honest ratings when conditions are excellent, good, fair, or poor
• Today and tomorrow at a glance; a longer outlook with Pro
• Time-sensitive reminders as your opening approaches
• Optional calendar awareness so busy hours are skipped
• A signature timeline that shows the day opening and closing — not a chart of numbers
