Unreliable
Additionally, we have tried to make a group multiple times and the members of the group are unable to access the group after it have been established. I’ve tried creating another group many times and it simply won’t work.
Please update and fix these bugs
Response from developer
Thank you for your feedback. We've made updates to address these issues. Previously, when an alert was published, the surge of users pulling live data at once caused the app to slow down or freeze. We've now fixed this: everyone still receives the alert notification right away, but when viewing the detailed information afterward, users using free version are served from a cache to keep the app stable, while Premium members get direct real-time access to latest information. If having the very latest information matters to you, Premium guarantees that even during high-traffic alert moments. We've also fixed the group access bugs from your review. Please give the app another try, and if anything still feels off, please let us know. Japan Alarts team
Deleting app
Response from developer
We're sorry Japan Alerts let you down, and we take the false alarms especially seriously on a safety app. Both problems have been fixed. The alerts firing when nothing was happening came from a server-side issue that could re-trigger earthquakes which had already passed. We found and fixed it, and that fix is already live for everyone, with no update needed. The stalling and glitches were fixed in version 2.0.3, now available. If you're willing to give it another try, we'd love the chance to earn back your trust. Either way, thank you for the honest feedback. Please stay safe. Japan Alerts team
話にならない
Response from developer
この度はご不便をおかけし誠に申し訳ございませんでした。実際の地震の際に通知を開けなかったとのこと、いざという時にお役に立てず心よりお詫び申し上げます。 ご報告いただいた「通知を開いても表示されない／開けない」不具合について調査した結果、地震速報が発表された際に多くのユーザーが同時にリアルタイムの情報にアクセスすることでサーバーに負荷がかかり、アプリが正常に動作しなくなっていたことが原因と判明いたしました。 この問題を解消するため、通知自体は今まで通りすべてのユーザーに即座にお届けいたしますが、詳細情報をご覧いただく際、無料版ではキャッシュ(事前に取得した情報)を表示することでアプリの安定性を確保し、プレミアム会員の方には引き続きリアルタイムの最新情報を直接お届けする仕様といたしました。緊急時により新しい情報をいち早く確認されたい方には、プレミアムプランもご検討いただけますと幸いです。 お手数をおかけしますが最新版にアップデートのうえ改めてお試しいただけますと幸いです。 今後も安心してお使いいただけるよう改善を続けてまいります。 Japan Alerts 開発チーム
Great app for non-Japanese speakers living or traveling in Japan
If your family member is going to Japan, or living in Japan, it will be a very useful tool.

Thanks for your review. Version 2.0 is a way better. Hope you will like it.
Constant stress!!!
Response from developer
Thank you for sharing your valuable feedback, and we apologise for the repeated notifications that caused stress not just for you, but for those around you as well. First, we’ve made an improvement regarding notification frequency: for a single earthquake, the Japan Meteorological Agency (JMA) may issue multiple updates (mainly to share additional information). In the version you were using at the time, our app sent a separate notification for each of these updates. Now, we only send a notification for the initial alert — any follow-up information from JMA is added to the details within the app rather than triggering additional notifications. Second, as for location-based settings, you can register the specific areas you want to receive alerts for, so you're not notified about earthquakes that don't affect you. Free users can set 1 location, and Premium users can set up to 6 (a home location plus 5 additional areas). We'd really appreciate it if you could update to the latest version and give it another try. We'll continue working to make the app something you can rely on with peace of mind. Japan Alerts Team
