About this app

Jutsu Signal is a dark-cyber network diagnosis entertainment app that observes your connection as a "technique".

- Quick scan
Diagnoses the connection where you are in a short time. Connection status, latency, and Wi-Fi reception are displayed as a technique, with S-D grade titles. Some values are simplified on-device measurements.

- Share your result
Generate 1:1 or 9:16 share images for social media.

- Wi-Fi Field Survey
Pick one Wi-Fi network and walk with your device to record reception strength spot by spot. Results appear as a color-coded heatmap (a relative layout with your starting point as the origin - not a floor plan or an accurate map; it does not locate the router precisely or guarantee coverage).

- Survey history and comparison
Surveys are stored on your device. Revisit, rename, delete, or pick two to compare side by side.

- 8 languages / 8 elemental skins
Japanese, English, Korean, Simplified Chinese, Traditional Chinese, Spanish, Brazilian Portuguese, and Indonesian. Switch the look with elemental skins: Ice Crystal, Flame, Gale, Thunder, Earth Vein, Radiant, and Abyss.

- Privacy
* All measurements are processed on your device; nothing is sent to our servers
* Location is used only while measuring a Wi-Fi survey, never in the background
* Coordinates, SSID, and BSSID are not stored
* Communication content is never collected
* The quick scan needs no location permission

Note: values in this app are simplified on-device measurements and do not guarantee line quality.
