Cloudbase builds your forecast from the weather models that scored best, chosen separately for each forecast detail and each day ahead. Within 250 km of Edmonton, Calgary, Grande Prairie and Ontario (California), each choice that could be scored was first or tied against GFS and the other models Cloudbase can serve there, on our own scoring of 19 months of past weather. Those scores come from the same history used to make the choices, and the app's accuracy pages show every one. No account required. No ads. Just weather. — FORECAST & RADAR — Detailed daily and hourly forecasts with temperature, precipitation, wind, pressure, visibility, and cloud cover — for Canada and the United States.

Verdict
The clearest difference is in-app purchases: Cloudbase Weather at none against Japan Weather Chart's 2. Cloudbase Weather also leads on ads (none vs shown) and update cadence (every 2 days vs every 2 months). Japan Weather Chart's advantage is iOS requirement (17.0 vs 26.0). On price and device support there is nothing between them.
