Measuring nano amp range current consumption




I am looking to buy one of joulescope, ZS-2102-A (angler circuits) or Otii (QOITECH) to measure power consumption and get graphs of current consumption for some low power BLE/ WiFi devices. Does any one have experience with these devices.

Circuit under test consumes between a few nano amps to 400ma @7.4v input (Lipo battery pack)

Have looked at EEVblog microcurrent etc., I really need the software which graphs consumption in real-time without the use of a scope. Appreciate any suggestions and real world experience using these or similar low cost tools.
