A few days ago, I was shopping in Google Play Store and I happened to come across the StashAway mobile application. I went on to check the developer information to confirm that it is a legitimate application.
For example, there are many fake WhatsApp applications out there, so be careful! Given the necessary permissions, these applications can actually spy/steal information from you. Read your files, messages, contacts, etc.
You might notice that the interface is slightly different but everything that is accessible from the web interface can be accessed from the mobile application which is great! Not sure why StashAway did not broadcast/market their mobile application yet.
Regardless, you can download the mobile application here:
