Monzo… A mobile bank that allows me to budget and track my spending, I get instant notifications when I buy something and can pay mobile contacts easily.
Spotify… Music on the go and good for in the car!
Peak… Bit of brain training
Google Maps… Have become very reliant upon!
Amazon… Love a cheeky mobile purchase!
OneNote… which I have saved on my OneDrive and can use on my iPhone and it updates onto my laptop.
