The biggest issue with the PlayMemories time lapse app is that it does not support Bulb mode, so you are limited to exposures of 30s or less. This may be ok for certain time lapse purposes but it renders the app useless for shooting star trails for example. I think this is a big enough flaw that Sony should disclose it clearly in the App info so users can know before they buy. Spending £8.99 on the app only to find out it doesn't work in Bulb mode was a rip off. Alternatively, Sony could fix the App so that it works with any length of exposure - that way it would be a truly integrated intervalometer, which would be a real advantage/plus on the a6000.
Despite having invested in the App, I ended up buying a stand alone intervalometer. JJC make one for the a6000 and it works very well, as do other generic brands. Do a search on eBay. As far as I can tell, there is no need for you to get a multi port converter, as the generic intervalometers are made for the a6000 and directly compatible.
