Amemil is an application that uses augmented reality (AR) and artificial intelligence (AI) to represent real-time rainfall information. The AI tells you when strong rain clouds are approaching, and you can check them as realistic images through the camera. * Main functions and features - Amemil has three modes: "2D" for map display, "3D" for AR display, and "Satellite Eye" for a bird's eye view of the weather from above. - Rainfall information is a composite of JMA radar data, with a resolution of 250m mesh, and is updated every 5 minutes. - Rainfall notification is a push notification with voice (Saori Onishi and Ari Ozawa) and radar video when rainfall is expected at registered points or at the current location within one hour. - In 2D mode, rainfall and lightning information is displayed in 10 shades, superimposed on the current location marker and map. - The AI learns from meteorologists' explanations and provides information on temperature and rainfall conditions in the user's vicinity, as well as forecasts for the future. - In 3D mode, rainfall information for a 10km radius is combined with the camera image as an animation of rain clouds, rain, and ripples in puddles. You can read the amount of rainfall by indicating the target direction. It can also play the sound of rain according to the intensity of the rain. - The "Satellite Eye" function allows you to view rainfall conditions across Japan, and by moving your iPhone, you can experience a realistic image as if you were looking at it from a satellite. - There is a demo mode that recreates heavy rainfall that has led to disasters in the past. - If you register as a member for 0.99 US dollars per month, you can use the rainfall forecast for the next 15 hours and GPS tracking mode. - You can post a video and image of the screen you are viewing with AR to SNS. If you post it, you can use the paid rainfall forecast and GPS tracking mode for 3 hours for free. * Support for widgets You can check the umbrella index, the rain forecast graph for the next 15 hours, and the weather radar map of the surrounding area on the home screen at any time. * Support for Siri shortcuts - Ask Siri, "What's the rain coming? and Amemil's AI will reply with the weather conditions in the area. * Support for Apple Watch - Rain radar is displayed on the map and a digital crown can be turned to see the forecast up to 60 minutes ahead. - Notifies you of approaching rain with animation. - Precipitation probability, satellite image, and precipitation forecast can be added to the watch face. * About Monthly Membership Price and duration of the monthly membership 0.99 US dollars / 1 month (counted from the date of application) / automatic monthly renewal You will be charged to your iTunes account. * Details of automatic renewal Your subscription will be automatically renewed unless you cancel the auto-renewal more than 24 hours before the end of your subscription period.

Verdict
The clearest difference is ads: Mercury Weather at none against Amemil's shown. Mercury Weather also leads on ratings volume (1.1K vs 1) and review sentiment (65% vs 43%). Amemil's advantage is rating (5.0 vs 4.6). On price, in-app purchases, monetization model and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Amemil sells 1 in-app purchase, starting at $0.99 per month and Mercury Weather sells 7 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.
Amemil holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Mercury Weather has 1.1K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 43% of Amemil's written reviews are positive against 65% of Mercury Weather's, so the app with the better star average is not the one people write more warmly about.
Amemil ships an update every 3 weeks, Mercury Weather every 10 days. The most recent releases landed on November 10, 2026 and November 7, 2026 respectively.
