## NimbusWx

NimbusWx is a spot weather forecasting app for iPhone that makes professional-grade numerical weather prediction data accessible. Most weather apps hand you a finished icon and a temperature; NimbusWx instead visualizes the raw output of the numeric models that industry experts actually use, turning data that normally requires desktop software into friendly, zoomable charts.

Where it stands apart is its AI layer. Since version 1.2 the app has included a customizable AI weather forecaster powered by ChatGPT. You control what type of weather data you care about and how the forecaster behaves, then use prompts such as asking about wildfire risk or skiing conditions, or even asking it to speak in a particular style. A 2025 update brought improved AI summaries and search for locations.

The app draws its data from SpotWx, a forecasting site used by professionals across North America and beyond. It supports the GFS, RDPS, HRDPS Continental, HRDPS 1km West, GDPS, NAM, HRRR and RAP models, letting you compare them for the same coordinates and inspect each model's simulated altitude and resolution before trusting its output.

**Pricing & Plans:** NimbusWx is free to download with optional in-app purchases for the pro tier via the App Store. Check the App Store listing for current pricing.

- **Any location on Earth:** Select any coordinates on Earth and pull spot forecasts without digging through regional weather sites.
- **Customizable AI forecaster:** Choose and customize a ChatGPT-powered forecaster that describes conditions in words, from wildfire risk to ski conditions.
- **Multi-model comparison:** Plot and compare GFS, RDPS, HRDPS, GDPS, NAM, HRRR and RAP model data in zoomable, scrollable charts.
- **Resolution transparency:** See each model's simulated altitude plus its spatial and temporal resolution so you know how much to trust it.
- **Saved favourite places:** Save the places you check often for one-tap access to current charts and summaries.

**Strengths:** Access to raw numeric weather model data, not just a finished forecast icon; Customizable ChatGPT-powered forecaster for plain-language summaries; Compare multiple professional models for the same coordinates; Free to try with an in-app pro upgrade

**Limitations:** The AI forecaster has drawn mixed reviews, with some users reporting intermittent outages; The App Store listing notes it is not verified for macOS; Advanced model detail is limited compared with the full SpotWx website

## Roxy - AI Voice Companion

Roxy turns your phone into a conversational companion that you interact with entirely by voice. Launch it and speak naturally; the app understands what you say and answers aloud, so it works well in situations where your hands and eyes are busy - driving with CarPlay, cooking, exercising or unwinding. The developer positions it less as a productivity chatbot and more as an always-available voice friend you can chat with about everyday topics.

Beyond plain conversation, Roxy packs a set of voice-driven activities. It plays trivia, word puzzles and 20-questions style games, offers interactive language practice and instant translation, and will humorously "roast" movies and TV shows or discuss books you are reading. In newer versions you can choose which underlying language model powers the conversation - including Claude, DeepSeek, Gemini or a custom model - and you can rename Roxy and adjust her behaviour. A subscription removes usage limits, and the developer states that certain regions can also lift soft language restrictions.

The app requires iOS 15 or later and is rated 13+ because some content themes are aimed at an older audience. It is a downloadable App Store product rather than a web platform, and access to the full experience is sold through auto-renewable in-app subscriptions.

**Pricing & Plans:** Free to download with in-app purchases. The App Store listing shows auto-renewable subscriptions of roughly $9.99 per month and $99.99 per year for full features, and a free tier is available with limits removed in newer versions. Prices vary by region and are charged through your Apple account.

- **Hands-Free Voice Conversation:** Talk to Roxy naturally in a voice-first interface and hear spoken replies, so you can use the app while driving, cooking or relaxing without touching your phone.
- **Voice-Based Games:** Play trivia, word puzzles, 20 questions and other casual games using only your voice for entertainment on the go.
- **Language Practice & Translation:** Hold interactive conversations to practise a new language, or ask for instant translations when you need them.
- **Choose Your AI Model:** Recent versions let you pick the underlying language model - Claude, DeepSeek, Gemini or your own custom model - to shape how conversations feel.
- **Customisable Companion:** Rename Roxy and adjust her behaviour so the companion fits your preferences, with regular updates adding features over time.

**Strengths:** Genuinely hands-free voice-first design, useful while driving or busy; Multiple activities beyond chat: games, translation and language practice; Lets you choose the underlying AI model, including custom ones; Available directly on the App Store with clear subscription tiers

**Limitations:** Only available for iPhone and iPad; no Android or web version; Some features and uncensored behaviour depend on region; Review volume is still low, so long-term reliability is hard to gauge
