I built Weathergraph to be the weather app I always wanted — clear visual forecasts, professional-grade data, and zero tracking. WHY OUTDOOR ENTHUSIASTS LOVE WEATHERGRAPH • Up to 7 days of hour-by-hour weather in one glanceable chart • Know exactly when rain starts: “Light rain 2:30–3:15 PM,” powered by Rainbow.ai radar + ML • Rain alerts up to 60 min ahead — plan your run, hike, or ride with confidence • Built for kite surfers and sailors: wind speed + gusts, direction, pressure trends, UV peaks, heat index • Works offline — forecast cached for 24 hours, even in the mountains or on travels • Privacy-first — no accounts, no ads, no tracking, no data sharing SEE YOUR WEATHER AT A GLANCE Weathergraph turns raw weather numbers into a visual narrative: • Temperature as a smooth gradient line — spot the warmest hour for your bike ride • Rain & snow as blue bars — taller bars = heavier precipitation • Sunshine breaks as real sun-rays between clouds — find the best window to head out • Wind with gusts and direction arrows • UV index curve — know when to apply sunscreen (hint: above 3) • Barometer trends to understand pressure-driven changes • Today’s highs and lows, sunrise, sunset and twilight, right in the chart YOUR PLACES, ALL IN ONE APP Save home, the mountains, your next trip — any place you care about.

Verdict
The clearest difference is in-app purchases: C4ST at none against Weathergraph weather widget's 12. C4ST also leads on iOS requirement (15.0 vs 17.0). Weathergraph weather widget's advantage is update cadence (every 5 days vs monthly) and chart position (#71 vs unranked). On price, ads and device support there is nothing between them.
