About

Rosetta Dash

Read full description

Rosetta Dash is a focused safety and trip-readiness display for road trips, remote travel, and camping. It is not a navigation app and never presents a driver-facing map. See what matters now: • Live heading, GPS speed, altitude, pitch, and roll from your iPhone’s sensors • Tap either attitude instrument to calibrate it to your phone’s mounted position • Current temperature, wind, and visibility • Air quality from Open-Meteo • Active NOAA/National Weather Service alerts when available Rosetta Dash is built for an at-a-glance cockpit view: large instruments, calm hierarchy, and safety conditions above ordinary status. Location is used only while the app is open to calculate local conditions and device instruments. Rosetta Dash has no accounts, advertising, analytics SDKs, or in-app purchases.

About

WASM Weather

Features
Read full description

WASM Weather gives you the forecast where you actually are — down to the neighbourhood, across all 22 countries of the Arab world. Most weather apps hand you one model's opinion. WASM is built on W.DMM, our own forecasting engine: it blends several of the world's leading global weather models into a single forecast, then checks it against real observations on the ground. When the models disagree, we settle it rather than passing the disagreement on to you. WHAT YOU GET • Hourly detail for the next five days: temperature, how it actually feels, wind, humidity, cloud, chance of rain and visibility. • The SWAS index: a single score from 0 to 100 for how workable each hour is, built from the factor that matters most in that hour rather than an average that hides it. • Severe weather made explicit: dust, fog, thunderstorms and heat stress are scored, not buried inside an icon. • Weather alerts for your location: a notification the evening before and on the morning of a day with rain, dust, wind, heat or cold. Switch them off whenever you like. • Your own settings: °C or °F, km/h or m/s, 12- or 24-hour time, applied everywhere in the app. • Favourites: follow the cities that matter to you and move between them with one tap. • Weather news in both Arabic and English. • A full Arabic and English interface, including right-to-left layout. BUILT FOR THIS REGION Forecasting the Gulf and the Levant is not the same problem as forecasting northern Europe. Dust, extreme heat, coastal humidity and sharp desert temperature swings each get specific treatment here, because they are what actually decides whether a day is workable. LOCATION WASM asks only for your approximate, city-level location, and for one purpose: to find the nearest supported area to you. Your location is not stored on our servers, and the app works without it — you can simply pick your area from the list. FREE WASM Weather is free and supported by ads.

Verdict

The call

The clearest difference is ads: Rosetta Dash at none against WASM Weather's shown. WASM Weather's advantage is update cadence (every 4 days vs every 2 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.
