TempsClair

You’re heading out the door, glance at the sky, and freeze. Is that cloud about to dump rain, or is it just a wisp of morning fog? Without clear, real-time data, you either grab a jacket you won’t need or get soaked. TempsClair eliminates that guesswork. It transforms raw meteorological data into a precise, hyper-local snapshot of what’s actually happening outside your window—right now, and in the next two hours.

What TempsClair Actually Does

TempsClair is a utility app built for quick, no-nonsense weather assessment. It pulls data from multiple atmospheric sensors and presents it in a stripped-back interface that prioritizes speed over flashy animations.

• Two-Hour Nowcast Engine
  The core feature is a rolling, minute-by-minute precipitation forecast. The app analyzes radar reflectivity and satellite imagery to predict rain or snow onset, intensity, and cessation within a 120-minute window. Results display as a simple timeline bar—green for dry, blue for light rain, red for heavy downpours.

• Multi-Source Data Fusion
  Rather than relying on a single provider, TempsClair cross-references readings from local weather stations, global forecast models (GFS, ECMWF), and crowd-sourced barometric pressure reports. This reduces the margin of error common in generic weather apps.

• Live Atmospheric Pressure Trend
  A dedicated pressure graph updates every 15 minutes. Rising pressure indicates clearing skies; a sharp drop warns of an incoming storm front. The graph shows the last 6 hours of data, giving you a tangible sense of atmospheric momentum.

• UV Index & Wind Gust Alerts
  The app tracks UV radiation levels (0–11+ scale) and wind gust speeds. If the UV index exceeds 6 or gusts top 40 km/h, a silent notification triggers—no buzzing, just a status bar icon.

• Minimalist Home Screen Widget
  A 1x1 widget displays current temperature, precipitation probability (as a percentage), and a single weather icon. No scrolling, no tapping—just a glance.

Key Advantages Over Generic Weather Apps

| Feature | Typical Weather App | TempsClair |
|---|---|---|
| Update frequency | Every 60–120 minutes | Every 15 minutes for pressure & radar |
| Nowcast granularity | Hourly blocks | Minute-by-minute for 2 hours |
| Data sources | 1–2 providers | 3+ fused sources |
| Notification style | Loud alerts with sounds | Silent status bar icon |
| Widget complexity | 4x4 with crowded info | 1x1 with essentials only |

Performance note: The app is built on a lightweight SQLite backend. It consumes under 15 MB of storage and runs without background location services unless you enable the “Frequent Updates” mode. Battery drain is roughly 2% per hour during active use.
