I'm looking for suggestions on what to apps and devices to get so I can keep maintaining my 2013 Avalon hybrid and to fix up my 2006 Prius. Goals: I'd like to be able to: check and fix HV battery health (Prius has red triangle on and battery fan full blast), check all codes (has had inverter pump problems in past) bleed brake fluid and flush other fluids (on both cars) check engine compression (Prius now, Avalon in about a year from now), and if at all possible, be able to sync TPMS sensors so I can change sets of rims with summer and winter tires respectively. Hardware: I have a 6 year old Lg G3 phone that bluetooth doesn't work very well on. I've always been kind of a Windows guy and mainly drive a Microsoft Surface 3. Are there any good Windows apps for working on Toyota hybrids? If not and my LG G3 doesn't cut it, what device would be best? I have thought about getting the new iPhone SE, but am not sure that's what I want unless it's a good choice for apps. And what OBDII connectors are best?? I see the Dr. Prius recommends the for both Android and iOS, in case I do go with an iPhone some day. Apps: Like I said, I have both a 2006 Prius and a 2013 Avalon hybrid to take care of. I'm aware of the Dr. Prius/Dr. Hybrid app that works with both. I think I've found the Torque app. What other apps would work well for me? I'll keep looking, but any suggestions are welcome. What I've tried: I have tried the Chinese Mini VCS with pirated Techstream software, but to no avail on both 32bit and 64bit versions of Windows. I'm not so sure I want to be using pirated software anyway, and although I drool over the idea of getting a Mongoose and subcribing to Techstream and TIS, I don't think I can really afford that. Maybe I'll get a Mongoose by itself and then subscribe to Techstream as needed, but I'm still up in the air on this one.
