There is no sound control on the iPad. Used to be but a recent update seems to have removed it. There is one on the iPhone version but none on the iPad version (any more).

But I notice several "where have the noises gone" and "we'll put them back" posts here so I wonder if putting them back has also removed the volume/mute control on the iPad.

That is beyond daft. Mandatory sound with no volume control (beyond silencing the entire phone, music, everything. How daft can this app get?

And I paid for a subscription and it just gets dafter.

I'm hesitant about negative appstore reviews but this new functionality deserves negative stars and a "complete rubbish" review.

Intensely annoying. Previously a sound mute control which has disappeared. 1st time I was looking around for a fire starting (camping in drought having used camping stove.

1st app ever to have needless sound output with no volume/mute. What were developers thinking?

For iPhone/iOS:
I was going to go premium but why spend all that money on something you can hardly read 'cos the text size is too small. Previous version apparently had text size function (according to this web site) but not in current version and no way I'm paying for n expensive subscription when it's such a nightmare to read (and I can't read the gust speed atall). And my eyes are tested every year and I have perfect vision!
