What's the most detailed weather app for iPhone?

I’m looking for a new weather app for my iPhone because the one I’m using now doesn’t have the level of detail I want. I need more in-depth information like radar, hourly breakdowns, and real-time alerts. Can anyone recommend the most detailed weather app for iPhone users based on your experience?

What’s Actually the BEST Weather App for iPhone? My Deep Dive

Alright, let’s be real for a minute: If you’re like me and you can’t step outside without checking three different apps to figure out if it’s going to rain, this post is for you. I’ve spent way too much time bouncing between weather apps on my iPhone, all hoping for the magic combo of accuracy, detail, and not being full of ads. So, if you want the scoop on which apps serve up the juiciest weather details, keep reading.


Weather Underground: Nerd Heaven or Info Overload?

First up, Weather Underground. I’ll be honest: This app feels like it was made for weather dorks (no offense… I’m in that club).

Why it’s awesome:

  • It pulls data from thousands of local weather stations, not just generic airport readings.
  • The “Wundermap” is like if Google Maps married a weather database and had hyperactive kids—radar, satellite, webcams, all on one map.
  • Crazy granular details, from barometric pressure to UV index.

But here’s the rub:

  • The interface can be overwhelming for the casual user. There’s a lot going on.
  • Some features sit behind a paywall.
  • Occasional delays in updating (seriously, just tell me if it’s raining now).
  • Ad-supported unless you pay for Premium.

CARROT Weather: Snarky, Customizable, or Just Annoying?

Now for CARROT Weather. This one divides the crowd. It’s either a revelation or you delete it after a day.

Here’s the scoop:

  • Super detailed weather reporting—hourly breakdowns, long-term forecasts, and fresh radar imagery.
  • Wildly customizable interface; you can tweak pretty much every data tile.
  • Did I mention the attitude? If you want your weather delivered with sarcasm, this is your jam.

Gripes I’ve got:

  • Some folks (me included) find the snark grating after a while.
  • The best features require a subscription. Not wild about another monthly charge tbh.
  • There are so many configuration options that it’s easy to get lost.

Get the dry facts: Apple Support - CARROT Weather


The Apple Weather App: Underrated Simplicity (But Lacking Depth?)

I almost skipped Apple’s built-in Weather app out of habit. But I went back, and you know what? It’s not bad—just, well, basic.

On the plus side:

  • It’s already on your phone. No downloads, no learning curve.
  • Clean layout, with easy-read screens and basic forecast info for anywhere you want.
  • Hourly and 10-day predictions, with key info like humidity, wind, and air quality (if available in your area).

Yeah, but:

  • Depth? Eh. If you want wind speed, UV, and radar detail, you’ll be left wanting.
  • Occasional glitches in severe weather alerts.
  • You’re at the mercy of Apple’s data suppliers, and some users feel the predictions are… generic.

TL;DR (because you’re probably just here for the recommendation)

  • Weather Underground: For data junkies who want every weather fact out there, and don’t mind a learning curve.
  • CARROT Weather: Wildly customizable, sassy, and feature-packed… if you’re into that attitude.
  • Apple Weather: Super easy, nothing to install, covers the basics—but won’t satisfy anyone who wants advanced radar or hyper-local data.

Hope this saves you from standing in the rain, staring at your phone, wondering what went wrong. If you want to dig into even more features (or fume about subscription fatigue), the official apps and Wikipedia articles linked above are a good start. Stay dry out there.

I’ll say it: most weather apps are about as reliable as my ex’s promises. @mikeappsreviewer already hit the main contenders, but let’s be honest, Weather Underground and CARROT are the usual suspects with their own baggage (ads, subs, annoyance, whatever). Here’s a hot take though—MyRadar is massively underrated if you actually want real-time radar. It’s not bloated with cutesy snark or endless data tiles; you get a blazing-fast radar that auto-updates as you zoom around the map and slick overlays for hurricane tracking, wind, futurecasts, and more. Alerts come in fast, sometimes too fast (prepare for a panic if there’s a thunderstorm three states away), but at least you’re never caught off guard.

Hourly breakdowns are baked in, widget support is solid, and you can actually use a bunch of its radar layers for free before getting nudged into Premium territory. Yes, the UI is a little, uh, “functional” rather than pretty, but who cares if you actually want to see where the downpour is? Plus, no snarky robot voice or walls of unreadable data.

Dark Sky used to be the king of hyperlocal, but Apple ate them and well, we all know how “innovative” Apple gets with native apps. Don’t get me wrong, the built-in Weather will do in a pinch, but it’s like getting weather from a bored Siri—meh.

Honorable mention: RadarScope. If you want meteorologist-level data, especially for storm chasing or ultra-detailed radar, nothing beats it—but unless you eat synoptic charts for breakfast, it’s probably overkill and a liiiitle intimidating.

So yeah, MyRadar for real world radar + alerts, CARROT for snark and customization, Weather Underground for trivia night with your meterologist buddy, and Apple Weather for when you’ve given up. Or just download all of them and live in app-switching purgatory like the rest of us. The most “detailed” app totally depends on if you want to nerd out on data, customize layouts, or just see if your barbecue is going to be ruined. Choose your fighter.

Honestly, after reading the deep-dives from @mikeappsreviewer and @waldgeist, part of me wonders if a weather stone on a string would be less complicated than some of these apps! Not to pile on, but while they hit the obvious big names, here’s a missing contender: Windy (yep, that’s the name). It doesn’t get as much love in the mainstream, but if what you want is pure weather nerdery (think weather geek, not your grandma’s sunshine smiley app), Windy is a beast.

You get a borderline obscene amount of data—layers for every paramater, live radar, cloud types, wind barbs, rain accumulation, lightning maps, even air quality and pollen (for all you allergy sufferers dying to plan your week). And unlike CARROT’s “hey look I’m snarky,” Windy skips the attitude and crams info onto the screen you never even knew you wanted. Actually, maybe you don’t want that much, because I’ve gotten lost just toggling layers and forgetting why I opened the dang thing.

On the other hand, if you care about hyper-local nowcasting and want clean, just-the-facts updates—no, Apple Weather’s not up to the task despite what the apologists say. I’m with @waldgeist that Dark Sky (rip) used to be the king there, and nothing else on iOS really measures up since Apple bought and, let’s be real, kinda neutered it.

MyRadar is way snappier for live radar, but holy moly that interface gives me ‘Windows XP shareware vibes sometimes. Still, if “did the rain JUST start up the street” is what matters, you’ll get addictively fast answers. But fine, if you’re a detail freak, Windy will drown you in charts, and it’s (mostly) ad free unless you want ALL the pro features.

Bottom line: pick Windy if you want to melt your brain with information, or MyRadar if you want actual, useful radar without the weather clown show. Just don’t expect any of them to get your forecast right every time. Weather is, after all, just professionally educated guessing.

If detail is your thing, let’s talk turkey: Windy (or Windy.com on the App Store) is basically the Swiss Army knife of weather apps for iPhone and honestly deserves more hype in these weather app cage matches.

Pros for Windy:

  • Staggeringly granular: global and local live radar, cloud layers (high/mid/low split!), ECMWF, GFS, and even lesser-known models like ICON and NAM at your fingertips.
  • Data candy: wind barbs, temperature overlays, precipitation accumulation, pressure isolines, weather fronts, and lightning tracking that updates crazy fast.
  • Visually slick: animation smoothness outpaces MyRadar (which is quick but visually clunky). And none of the in-your-face quirk that CARROT brings.
  • Pollen, air quality, wave heights, and even aviation layers if you’re a pilot or just low-key obsessed.

Cons for Windy:

  • Interface hits overwhelming status quick. It’s almost analysis paralysis with all the toggles and map layers—takes time to tune it to your needs.
  • Hyper-local alerts and notifications are weaker than Weather Underground or CARROT Weather, so you might miss that “grab an umbrella NOW” vibe.
  • Some pro features (extra models, higher-res radar) want you to cough up cash, but the core is super usable free.

Compared head-to-head: Weather Underground wins on crowd-sourced local data and old-school forecast tables, MyRadar is faster if all you care about is radar and notifications, and CARROT Weather’s customization is wild if you like your weather with a dose of personality.

Here’s my 2¢: For the nerdiest, map-focused weather detail on iPhone, Windy blows the others away, and if you vibe with data-driven map visualizations more than snark or tweets about the rain, it’s a solid bet. Still, grab a couple—no shame in running Windy alongside MyRadar for the big picture and those twitchy nowcasts. Weather can humble any app, so redundancy is smart!
