CARROT Weather vs. Weather Underground
CARROT Weather is published by Grailr LLC and has been on the App Store since 2015-03-19. Weather Underground is published by Weather Underground, LLC and has been available since 2011-12-21. Both are free to download and both sell subscriptions, and neither developer publishes a price for those subscriptions on its own site — a coincidence worth noticing before anything else. What separates them is what the money buys: CARROT sells capability in two tiers, and Weather Underground sells the removal of its advertising alongside a longer forecast. This comparison is built from what each developer publishes — App Store listings, CARROT’s support FAQ and press kit, and Weather Underground’s FAQ — with every claim sourced and anything unverifiable listed as such.
Everything below comes from published sources, checked on 2026-08-24 and linked in each section. Where the sources don’t answer a question, it’s listed under What we couldn’t verify rather than guessed at.
CARROT Weather
A heavily customisable weather app with a written personality, selling two paid tiers that unlock data sources, notifications, maps and widgets.
Weather Underground
An ad-supported weather app built on forecasts from a network of personal weather stations, selling ad removal and a longer forecast.
The cheapest way to pay Weather Underground buys you nothing except the absence of advertising. Nothing CARROT sells is priced that way, because CARROT has no advertising to remove. Deciding between them starts with whether what bothers you is a missing feature or an ad.

Feature comparison
| Field | CARROT Weather | Weather Underground |
|---|---|---|
| Differs: Advertising | Not mentioned in its App Store description or its FAQ, and nothing it sells is described as removing advertising | The free app carries advertising. Its listing describes removing all ads by purchasing an annual subscription, and its FAQ names monthly and annual Ad Free plans |
| Differs: What the paid tiers are | Premium and Premium Ultra, plus Premium Family, which its FAQ describes as Premium Ultra shareable with up to five family members through Family Sharing | WU Premium, sold monthly or yearly, and a separate cheaper WU Ad-Free subscription sold by the year |
| Differs: Where the prices are published | Not on the FAQ, which describes all three levels without a figure. Figures appear on the press kit, attached to a past release, and in the App Store in-app-purchase list, which does not match it | Not on the developer’s FAQ, which describes memberships without a figure. Figures appear only in the App Store in-app-purchase list |
| Differs: Weather data sources | Foreca by default, with Premium members able to switch to Apple Weather, AccuWeather, Tomorrow.io, OpenWeather or Xweather, plus regional sources and personal weather stations from WeatherFlow/Tempest and Netatmo, per its FAQ | Its own forecasts, drawing on a network of personal weather stations contributed by users, per its App Store description. No source switching is described |
| Differs: Geographic limits | Stated plainly. Its FAQ says certain notifications and map layers are available only in certain countries, and lists each by region | Not described. Neither its listing nor its FAQ states which features vary by country |
| What a subscription adds beyond features | Its FAQ states the app is free to download with a 7-day free trial of the Premium Club | Its listing describes Smart Forecasts and extended hourly forecasts up to 15 days ahead as subscription features |
| Radar and maps | A map layer list running from radar and cloud cover to wildfires and fronts, with availability varying by region, per its FAQ | Interactive Nexrad radar and severe weather alerts, per its App Store description |
| Differs: Minimum iOS | 15.0 | 14.0 |

Where each one fits
CARROT Weather is the one to look at if you want to choose your own forecast. Its FAQ names Foreca as the default and lists a set of sources a Premium member can switch between, along with regional providers and two kinds of personal weather station, which is a degree of control the other app does not offer at any price. It carries no advertising in anything either developer publishes. The costs are two. Its paid features split across two tiers rather than one, so the notifications many people want sit on the more expensive of them. And a large part of what it sells is geographically restricted — its FAQ is explicit that certain notifications and map layers exist only in certain countries, which means the same subscription delivers materially different products in different places. What CARROT Weather costs works through both tiers, the regional lists and the question of where the figures are actually published.
Weather Underground is the one to look at if your objection is advertising rather than absence. It is the only app of the two that shows ads, and it is also the only one that will sell you their removal on its own, separately and more cheaply than its feature subscription — a pricing shape that is unusual and that suits someone who is content with the free app apart from what is on the screen. Its forecasts draw on a network of personal weather stations contributed by users, which is the thing it is built around. Against that, nothing in its published material describes switching forecast providers, its FAQ does not say which of its features vary by country, and its own site names no price for any of its memberships.
Neither developer, in other words, will tell you what its subscription costs without sending you to the App Store to find out. That pattern is common enough across developers that it has its own page here. CARROT is also set against a smaller and quieter rival in CARROT Weather vs. Hello Weather.
What we couldn’t verify
These are questions the published sources do not answer. They are listed here unresolved rather than guessed at.
- What CARROT’s subscriptions currently cost. Its FAQ names no figure, its press kit’s figures are attached to a past release, and its App Store in-app-purchase list carries more figures than either page accounts for
- What CARROT Premium Family costs, or whether it is still sold. It is described on the FAQ and in the App Store description, but no item of that name appears in the App Store in-app-purchase list
- What CARROT Premium Mini is. It appears in the App Store in-app-purchase list and is named nowhere in the FAQ or the press kit
- Which features belong to CARROT Premium Ultra. Its FAQ and its App Store description give different lists for that tier
- What CARROT does with no subscription at all. Its FAQ describes the trial and the paid levels without stating what the free app retains once the trial ends
- Whether Weather Underground’s WU Premium includes ad removal, or whether the cheaper Ad-Free subscription is required for that as well
- Which Weather Underground features vary by country, which neither its listing nor its FAQ addresses
- Whether either app’s in-app subscription price matches any price on the developer’s own site, which App Store listings do not show
- How accurate either app’s forecasts are in practice, which no published source establishes for either
