Listen I don’t do reviews, and when I do do with use I’m trying to be petty and disrespectful as possible to the creator who made something horrible that I paid for. You are not the creator. I wanna kiss you for the magnificent work that you have done on this app and how it works 1 million times better than the government official notifications. You deserve piles and piles of love and ice cream for this. I will donate to you to keep you going because this is how you make an app and you’re amazing for it you are so amazing for it I don’t do Reviews Listen I don’t do reviews, and when I do do with use I’m trying to be petty and disrespectful as possible to the creator who made something horrible that I paid for.

A fantastic, completely free app that I think more people should definitely know about when in Japan! Not to mention the EVA theming. Thank you, developers ❤️ A beautifully designed app for weather and earthquake warnings. A fantastic, completely free app that I think more people should definitely know about when in Japan!

This app is a must-have for residents of Japan. I like it so much that I would be willing to pay a subscription for it. It’s incredible that it’s offered for free. It has full bilingual support in Japanese and English, and the English machine translations are excellent. When the Noto Ishikawa earthquake occurred, NERV sent me a warning notification in advance with time to arrive at my geolocation with estimated intensity. Godlike capabilities. Those who don’t know this app are left in the dark. Must-Have App for Japan Residents This app is a must-have for residents of Japan.

Am not one to usually write app reviews but from the beautiful design to clean, in-depth features and maps, I am impressed. Shows detailed present and future severe weather events, has great earthquake realtime features, and is an overall smooth app. Fantastic Am not one to usually write app reviews but from the beautiful design to clean, in-depth features and maps, I am impressed.
