Yes, Hybrid Assistant shows gas and electricity consumption, battery temperature, regen braking details while driving and idle. It works through OBD. It appears that only Toyota & Lexus are supported. Also, it is free. I could not see anything similar for Honda, if there is, I would like to try.
I don't know anything about that Hybrid Assistant app, but there are OBDII devices and apps that work with the Clarity PHEV. One such combo from Autel has been much discussed on this forum. Here's one post. Here's a long thread about specifically obtaining the battery capacity information.Does anyone know if there is a free smartphone app (android) that supports hybrid Honda cars like the Hybrid Assistant for Toyota/Lexus?
