What's new

Version 2.1 · Nov 3, 2026

iPerfman 2.1 brings a shareable speed receipt and a choice of speed units to everyone, nine iperf3 connection options to Pro, and many fixes. New for everyone - Speed receipt: share a saved result as an image. The server address is hidden unless you choose to show it. Available on iOS and iPadOS 16 or later and macOS 13 or later. - Speed display unit: choose Auto, Mbps or Gbps. Auto now picks one unit from each test’s peak, so readings from a test that passes 1 Gbps no longer mix Mbps and Gbps. - Online help opens the user manual on iPerfman.com in the app’s language. The privacy policy and terms of use also follow the app’s language. New in Pro - Connection options in Additional Parameters: address family (Automatic, IPv4 or IPv6), client port, block size, socket buffer, TCP MSS, TCP NoDelay, TOS byte, IPv4 Don’t Fragment and Get server output. Like the rest of Additional Parameters, they require Pro. They are saved with each record and carried into Retest, comparisons and reports. Improvements and fixes - The test engine is now iperf3 3.22. Option limits and defaults are unchanged. - An invalid port now shows an error before the test starts, instead of connecting to port 5201. In Additional Parameters (Pro), durations must be whole seconds; a value such as 0.5 is now rejected before the test starts. - Live, history and comparison charts now use the same axis range for the same results. - IPv6 endpoints are shown as [address]:port. - History details keep their charts and summaries up to date, even in very large histories. - The log view previews the last 32 KiB of a long log; sharing or saving still gives you the complete file. - On iPhone and iPad, text scales up to the largest standard size (XXXL); larger accessibility sizes display at that size. Several screens that were cut off at large text sizes now fit. - Settings are grouped into Preferences, About and Legal. Switches have clearer edges in dark mode, and when the appearance follows the system, pages that are already open switch with it.
