SymNote is the only Symbian client for Simplenote, written in Qt and a quality one for that matter. The user interface is simple and effective. Without any bling the interface provides the user with all Simplenote functions and more.
The main scren has a search field so you can search trough your notes or you can filter them using tags.
You can create either simple text notes or checklists. The Simplenote service does not support checklists natively, but the author of the app, Talv Bansal has gone the extra mile to bring this functionality to the app. So not only does the app provide notes support but it can help you do your shopping too. I for one share the same Simplenote account with my wife and if there is ever anything she needs me to buy, she just creates a checklist on her phone and I can see it on mine in a matter of seconds.
...There's not much else that can be said about SymNote. The app just works and it's my main workhorse. I wrote this entire review using SymNote and the Nokia Betalabs Swype keyboard. SymNote has only a paid version that you can..
