>>>>I juts produced a similar system for a logistics company with signature capture etc One thing you should look out for is some windows phones use an embedded internet explorer that doesn't support some html 5 elements, particularly the canvas element. As the people where tied to the (rubbish) phones by contract we had to use a product called zetakey as their browser which works ok but there is a license cost. Having said that developing in html with local storage was a lot easier than trying to produce a seperate app.

>>>Do you have any specific suggestions as to what "html with local storage" approach you used? I am testing a web application (that is almost finished) but I see that some customers will ask for an off-line use. So I need to start learning and maybe incorporating into my pages already. TIA.

>>I used webSQL which worked very nicely. Its is deprecated http://programmers.stackexchange.com/questions/220254/why-is-web-sql-database-deprecated but because I knew what browser would be used that wasn't an issue as it was supported. If I re do the mobile web app to be publicly available I may alter to something else.

>Thank you for your reply, Nick. This is all new to me so I will see (study) how applicable it is for my app. Right now I can even imagine how to do it without some kind of a "light" version of DB engine on a tablet device (maybe this is what webSQL is). Anyway, I will read the references your suggested and maybe I will see the light.

I was a bit puzzled where the data ended. In chrome the data is stored at : chrome://settings/cookies/.
