* *It's based on a single server* run by Open Whisper Systems. That's a single point of failure and ought to be a big red flag (of the sporting rather than the socialist variety) as a possible locus for concentrated nefariousness.
* *It requires the installation of Google Play*. If you already have Google Play installed on a stock Android OS then this doesn't increase your security problems, but for other more secure Android variants it's a massive increase in attack surface.
* *It depends enturely upon the Google message pushing system*. That means that Google /has the complete and corresponding social graph of all Signal users/. Remember that metadata in aggregate is much better than having the content of messages. At any time Google could decide that it doesn't want to support Signal, or in adverse circumstances they could be leaned upon by the usual agencies or government cronies.

* What is the most secure chat app to use on mobile?
On mobile there are various options. The apps which are likely to be most secure are ones which have end-to-end encryption enabled by default and which can also be onion routed via Orbot. End-to-end encryption secures the content of the message and onion routing obscures the metadata, making it hard for a passive adversary to know who is communicating with who.
