Best Couch to 5k app?

[Fuckwheresitgone]

Can anyone recommend a good 'couch to 5k' running app? I have an old iPod which won't accept the new NHS couch to 5k app, as mine is now an out dated operating system.
Don't mind paying for a good running app, but I want to be able to listen to my own music....I've tried the Laura podcasts....but can't get on with the music 😬😂
I'm a complete beginner, but really want to get fit and lose weight, so any suggestions I'd be really grateful.

Anybody?

I use red rock running app, not sure if you'll be able to get it on your iPod though if you can't get c25k nhs one?
It's got loads of different running programs such as start running, 5k 10k, 1/2 marathon etc , run for weight loss or you can time/map a free run. It's free but you can upgrade to a paid version too but I haven't needed to.
