Discover the invisible universe right in your pocket! SORAMAME is an innovative citizen science app that transforms your smartphone into a real cosmic ray detector. Every second, invisible high-energy particles from deep space are raining down on Earth. By using your device's camera sensor, SORAMAME allows you to capture and record these microscopic cosmic events. Whether you are a science enthusiast, a student, or just curious about the universe, you can easily contribute to global space research. Simply cover your rear camera to block out all light, press play, and let your smartphone catch the invisible hits from the cosmos! ## How It Works Your smartphone's CMOS image sensor is highly sensitive not just to visible light, but also to high-energy particles like muons. When the camera is completely shielded from light, the sensor acts as a particle detector. When a cosmic ray strikes the sensor, it leaves a faint but detectable signal—which SORAMAME captures and analyzes in real-time. ## Key Features Real-Time Detection: Watch your screen as cosmic ray hits are detected and recorded instantly. Global Observation Map: See where cosmic rays are being detected around the world! Your data contributes to a global map shared by other citizen scientists. Offline Mode: Exploring off the grid? No problem. SORAMAME saves your detection data (images and coordinates) locally when you are offline and automatically uploads it to the central server once your network connection is restored. Privacy-Friendly: Your location data is slightly blurred on the public map to ensure your privacy remains fully protected. Easy Setup: No extra hardware required. Just a smartphone and a dark environment (or a simple piece of black tape to cover the lens). ## Important Note for Accurate Measurement To detect cosmic rays accurately, the camera sensor must be in complete darkness. Please shield the rear camera from light entirely. The app includes a light-leak detection feature and will alert you (ERROR: Please shield the rear camera from light) if the environment is too bright. For best results, we recommend leaving the app running for at least 3 hours to stabilize the background noise learning. Join the SORAMAME project today, and let's map the cosmic rays of our universe together! https://soramame.n.kanagawa-u.ac.jp/en/ ## Key features - Real-time cosmic ray detection - Global observation map - Offline data saving - Privacy-friendly location blurring - Easy setup with no extra hardware - Light-leak detection ## Recent user reviews (1 of 1) All indexed reviews: https://appshunter.io/ios/app/cosmic-ray-detector-soramame/id6444093470/reviews.md ### 5/5 — 👍 *2026-02-26* Очень интересно смог прикоснуться к космосу дома **Developer response:** Спасибо, что пользуетесь нашим приложением. ## Frequently asked questions about Cosmic Ray Detector SORAMAME ### What is SORAMAME? SORAMAME is a citizen science application that transforms your smartphone into a cosmic ray detector. It uses your device's camera sensor to capture and record high-energy particles from deep space. ### How does SORAMAME detect cosmic rays? The app leverages the sensitivity of your smartphone's CMOS image sensor to high-energy particles. When the camera is completely shielded from light, the sensor acts as a particle detector, capturing signals from cosmic ray strikes. ### Can I use SORAMAME offline? Yes, SORAMAME supports an offline mode. It saves your detection data, including images and coordinates, locally and uploads it to the central server once your network connection is restored. ### Is my location data private with SORAMAME? Yes, SORAMAME is privacy-friendly. Your location data is slightly blurred on the public map to ensure your privacy is fully protected while still contributing to the global observation map. ### What is the recommended usage time for SORAMAME? For accurate measurements and to stabilize background noise learning, it is recommended to leave the SORAMAME app running for at least 3 hours. ### Does SORAMAME require any special hardware? No, SORAMAME requires no extra hardware. All you need is a smartphone and a dark environment, or a simple piece of black tape to cover the lens for complete light shielding. ### What devices are compatible with SORAMAME? SORAMAME is compatible with iPhone, iPad, and iPod devices. It is suitable for users aged 4 and above. ### How often is SORAMAME updated? The latest version of SORAMAME is 3.96, and it was last updated on April 30, 2026. This indicates a commitment to ongoing development and improvements. ## Version history (last 5 releases) ### 3.97 — 2026-08-19 We have fixed the Function for uploading data stored in device when network has recovered. ### 3.96 — 2026-04-30 New Feature: Offline Mode! Take your cosmic ray detection off the grid! We've added a highly requested Offline Mode, allowing you to continue your observations even when you don't have an internet connection. Whether you are hiking in the mountains, flying on an airplane, or exploring underground, SORAMAME will now securely save your detection data and images locally on your device. Once you're back online, the app will gently prompt you to upload your saved data to our global server. Keep exploring the universe, wherever you are! ### 3.95 — 2026-04-26 New Feature: Offline Mode! Take your cosmic ray detection off the grid! We've added a highly requested Offline Mode, allowing you to continue your observations even when you don't have an internet connection. Whether you are hiking in the mountains, flying on an airplane, or exploring underground, SORAMAME will now securely save your detection data and images locally on your device. Once you're back online, the app will gently prompt you to upload your saved data to our global server. Keep exploring the universe, wherever you are! ### 3.94 — 2025-06-24 We added "Reset Screen" button and fixed few bugs. ### 3.93 — 2025-06-12 Fixed problem with threshold level adjustments. ## Apps similar to Cosmic Ray Detector SORAMAME | App | Rating | Price | Category | | --- | --- | --- | --- | | [Chronomap in Cosmos](https://appshunter.io/ios/app/chronomap-in-cosmos/id6642644551) | — | $0.99 | Education | | [Global Warming Science & Model](https://appshunter.io/ios/app/global-warming-science-and-model/id1441249328) | 5.0 (2) | $19.99 | Education | | [SoroRoom](https://appshunter.io/ios/app/sororoom/id1239288027) | — | Free | Education | | [trinamiX Spectroscopy](https://appshunter.io/ios/app/trinamix-spectroscopy/id1540117635) | 4.0 (1) | Free | Education | | [PHENOM UFO](https://appshunter.io/ios/app/phenom-ufo/id6450217112) | 3.4 (17) | Free | Education | | [SNEWS Events](https://appshunter.io/ios/app/snews-events/id1635008227) | 5.0 (3) | Free | Education | ## More apps by BLUEPAGE Greetings LLC - [BLUEPAGE 出産内祝いカード](https://appshunter.io/ios/app/bluepage/id1444989419) - [RURIPI](https://appshunter.io/ios/app/ruripi/id1608828888) - [RURIPI Winter](https://appshunter.io/ios/app/ruripi-winter/id1659532007) - [RURIPI New Year](https://appshunter.io/ios/app/ruripi-new-year/id1659950530) - [RURICollage](https://appshunter.io/ios/app/ruricollage/id6444717172) All apps by BLUEPAGE Greetings LLC: https://appshunter.io/developer/1444989418 ## Related topics [icecubear](https://appshunter.io/ios/topics/icecubear) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
