Nubi Do is the iPhone/iPad app that was recently featured by FreeAppADay as their Featureed Free App, and received a 9/10 rating from AppCraver.com!

Any time a salesman shows off a device like this, they always mention how handy it will be to organize your to-do list, right? But when you get it home, you find the default calendar is pretty bare-bones, and there are a huge variety of scheduling apps on the market – how do you know which one you'll like best?

Trial and error, usually – or you can read around the internet and look for user reviews and articles showcasing the best of the best. The trick there is finding honest articles, and not ones written by the app distributor. Cunning of them, eh?

Nubi Do is a totally free app, which is surprising, considering how versatile and effective it is. Featuring an integrated calendar feature and multiple task attributes, you can search your calendar easily and instantly see what you'll be doing on any given day, and why.

It syncs with Google Spreadsheet, too – so you won't accidentally miss an appointment because you forgot to add something from the work calendar.

User reviews are full of raves for Nubi Do, and future updates are only improving what has been called a five out of five star app. How long, then, before it won't be free anymore? Try it out now, while you can still see what it can do for you for free!

You'll need a device running iPhone OS 3.0 or later, and 1.5 MB of storage space – Nubi Do is more about function than decoration, which helps keep the file size down.
