SignNow is an app for the web or your smartphone which allows you to annotate and add to pdf documents as well as sign and date them with your very own electronic signature. Super easy to use and very stable.
We were faced with having to sign and send a number of legal documents while we were in Spain with no ready access to a printer, not to mention the hassle of mailing a hard copy of the documents all over the world. After a search on-line we found SignNow, a free app for the iPhone or other smart phone. Its is super easy to use and very straightforward to append your (or multiple )signature(s) or add text to a pdf. When completed the app lets you email a copy of the signed document to the recipient. Easy as that.
The folks we have dealt with recently were overjoyed to have an electronic version of the documents, as were we to have saved timer and money as well as have an archived signed copy of the documents in our files.
iTranslate is a must have app if you are traveling to a country that does not speak your language. We used it extensively in Spain (even to do some of our language class homework!). Really fast to use in the moment when you need to know a word, like beer, in a foreign language. It even speaks the word for you if you want to understand the pronunciation.
The only proviso in using this app is that you will need wi-fi or a local cell signal to use it. Not always possible when on a shorter holiday.
