Netstat

A network status app for Apple iOS — discover which servers and ports are being used on iPhone®, iPad® and iPod touch®. Monitor your device’s TCP connections for uploads and downloads (IPv4 only) and export the list as CSV. Very useful for programmers, developers and curious users!

更新履歴
►Important Notice: This version is compatible with iOS 9 and earlier only. Apple has blocked its functionality in iOS 10.0.◀

Here’s what you get for free:
• Updated for iOS 5.
• Revised display format: port labels now appear first.
• Bugfixes & internal compatibility changes.
• Minor cosmetic changes.

What’s New with In-App Purchase:
• If you already paid for “All Features”, these have been added for free:
• Audio mode: beeps on connection activity, can play in background.
• Delta mode: filters the list to show new activity only.
• Custom sort order (by most recent activity, duration of activity, number of bytes downloaded/uploaded, server IP address/port).
• IP address display mode.

NB for existing users: if you get a message that “Netstat could not save your data. Your device might be full” this is actually due to a schema change. Simply tap Erase.

NB. Some worldwide hardware variations may still see connections listed as being very long (a hundred hours). Please report this using in-app feedback so that I can find out which models are affected. Thank you!
