From the developer:
Pymakr is a fully featured IDE that connects to your Pycom devices via Telnet Server or serial port, runs your code on the fly, manages the internal file system, synchronizes your code instantly and runs it with just one click. It also takes care of firmware upgrades and includes a built in console that interfaces with the MicroPython REPL.
