Thanks Jahzara. I'm not the iphoner, my DP has one.

The counter on this website shows what a simple contraction timer can do in terms of building up a record and calculating/recording the interval between contractions ... Contraction Master: Your FREE, online contraction timing assistant!

Anyhoo I think i'll go with something simple like the above. I quite like the idea of having the record afterwards and also not having to squint at the clock or write down numbers if trying to sleep through early labour. (I'm sure we still won't be hitting that little button once labour is well established, Kitten - especially not when I'm 'about to give birth'!!)

I guess I should have posted this question to the technology section

Thanks all for your input
