Description

Timeline WX
Your next 48 hours, visualized. Built specifically to push the limits of the Pebble Time 2's high-resolution display. Whether you're coordinating a Scout campout, dialing in your morning commute, or tracking incoming storms, Timeline WX delivers precision meteorological data at a glance—no squinting required.

Instead of static daily summaries, smoothly scroll through a continuous 48-hour timeline. We’ve stripped away cluttered text and replaced it with clean, data-driven visual indicators so you can assess your environment instantly.

⚡ The v2.1 Architecture

Instant Offline Resume: Your timeline is cached directly to the watch's flash memory. Launch the app and see your forecast instantly, even if your phone is disconnected.

Auto-Pruning Timeline: The watch continuously syncs with the hardware clock to automatically hide past hours, ensuring your scroll always starts exactly at "Now."

Ultra-Battery Optimized: Completely rewritten to run natively on the Pebble OS background clock, reducing battery drain by up to 98%.

🔥 Smart Environmental Warnings
Stop reading numbers and start seeing conditions. Timeline WX actively processes combinations of temperature, wind speed, UV, and humidity to color-code threats:

Dynamic Hazard Badges: A colored badge sits directly behind the weather icon based on a custom algorithm. Yellow = Uncomfortable (muggy/hot/cold); Orange = Warning (high winds, severe UV, approaching storms); Red = Dangerous (extreme temperatures or severe weather).

Temperature Alerts: Values turn Red when blistering hot (90°F+) and Blue when freezing (32°F and below).

High Wind Warnings: Wind speeds turn Orange when gusts exceed 20 MPH—perfect for knowing when to tie down the tent fly.

Midnight Dividers: High-contrast double lines and red timestamps explicitly mark when the forecast crosses into a new day.

☔ Intuitive Rain & UV Tracking

Rain Pie Charts: Ditch the confusing percentage text. Custom blue pie charts show you exactly how likely it is to rain, hour-by-hour.

UV Safety Bar: A dynamic, color-coded safety bar runs down the right edge of the screen, letting you know exactly when you need sunscreen (Green to Purple scale).
