What are some of the best PRN apps for nurses to pick up Extra shifts such as matchwell or shiftkey?

CareRev. Haven’t worked a shift yet due to delays in onboarding that come down to limited facility staff available to train new CareRev contract workers, or full
Orientation classes at said facilities. It’s taken since the beginning of November to get background checks, health assessments, respirator fit testing, drug testing, competency testing and provisioning completed. I’m just waiting until 2/28 to complete orientation at one facility. I just got clearance/provisioning done for another that I imagine will have orientation in march sometime. THEN I can pick shift and work PRN.I’ve worked with careRev staff RNs and they’re really great nurses! And support staff for careRev has been great too! It’s an experiment in professional freedom that I believe has been, and will be, totally worth it!!
