Onmi is a travel and navigation application available for iPhone users. Developed by Hoang Tu Dao, this free app aims to minimize PC dependency for network analysis and API debugging tasks. With Onmi, users can perform in-depth analysis of network systems, including public IP and network reverse. API debugging can be done conveniently using both direct and GET methods.

One of the key features of Onmi is the ability to ping any server on the user's network, providing valuable insights into network performance. Additionally, the app offers a feature to access free shared WiFi networks in the vicinity, which can be useful when in need of internet connectivity.

For users looking for more advanced features, Onmi Engineer provides an extended version with unlimited IP lookup requests, server ping measurement, an online tool for POST requests, ad-free experience, and offline access to shared WiFi networks.
