+# #️⃣ Hex Viewer
+
+Hex Viewer application for Flipper Zero!  
+The app allows you to view various files as HEX
+
+**Some facts**:
+- Written with pure C in a very simple and effective manner
+- Tested on files up to 16Mb
+- Very effective: calls `canvas_draw_str` 8 times during repaint and that's almost it
+- Can also view text representation of bytes (makes it kinda poor man's text viewer)
+- Has "Scroll to ..." feature which allows you to jump to any percent of file
+
+Feel free to send PRs! 
+
+App URL: https://lab.flipper.net/apps/hex_viewer
+Catalog's manifest: [flipper-application-catalog/applications/Tools/hex_viewer/manifest.yml](https://github.com/flipperdevices/flipper-application-catalog/blob/main/applications/Tools/hex_viewer/manifest.yml)
