Sometime last week I released my latest hobby project on the Ovi store. It is a QtQtuick application targeted at Symbian^3 based Nokia smart-phones.
For now it only features capabilites of a free account, since that is what I have myself.
Also worth noting, is that it is an online-only application at the moment. Adding offline capabilities to a future version is on my todo list however.
