I read about what sounded like a very useful app a couple of days ago but instead of installing it straight away, have now completely forgotten what it was for or called. Made me think though that maybe you might have some good ones to share.
I love Spotify. I only have the free version but it's good enough. This is on my phone. I also love Shazam. It identifies songs and even links up to Spotify so you can add them to a playlist. I've made quite a few playlists. I like to listen to music while I'm working in the kitchen but I really hate radio DJs with their rubbish talk and annoying cheeriness. This suits me well as I can listen to my choice of music and apart from a few ads it doesn't have talk.
If I want talk radio then I use the podcast app. I subscribe to quite a few podcasts (all free). My favourite is The Infinite Monkey Cage with the wonderful Brian Cox. They have guests that include serious scientists and comedians. It's a mixture of very funny with serious science. I've learned a lot from it and it makes me laugh.
I've just realised your title is useful apps. These are entertainment, sorry.
Actually I've recently downloaded an app called " Find My Car" . You set it when you park and it will lead you back when you can't remember where you parked. Useful in big car parks. Saves me wandering round wondering which row I parked on.
Any app Magggzzz. I like Spotify and Shazam too. I remembered where I read about the apps - in the Waitrose magazine that I picked up this week and they caught my eye as we’d been talking about stress, etc. There is Relaxation Library and the other is called Find time for reflection.
