In reply to Doug:
> Many thanks, so few real advantages, other than maybe being able to read articles 'off line' (although I find Le Monde unreadable without blocking adverts & I'm not sure what flashing adds the app will have). So how come they seem to be everywhere ?
Well I think we've oversimplified but it's a horses for courses situation. Partly because lots of people like my clients believe the hype and decide they must have an app, there are so many out there.
But select apps do specific jobs very well. Just looking on my phone at the apps I have where I would either prefer them over a website, or they simply wouldn't work with a website include:
Spotify
Instagram
Facebook
Youtube
Strava
Garmin Connect
Twitter
Swarm
Weather Crave (was La Chaine Meteo, it's changed names)
Economist
Guardian
WhatsApp
Netflix
Google Translate
Tunein Radio
Credit Agricole
Gmail
Mail and Calendar for work
Pretty soon you get quite a long list. These are apps I use every day too, not stuff I've downloaded and don't often touch. Just try stuff and if it suits you keep it - if not, don't.
