Don’t bother

Only gave this 1 star because it wouldn’t allow 0 star. Pop ads every time I write a new note.

Pop up ad in the first 30 seconds of opening it then it crashed.

Simple, Customisable, Versitile

I already had a checklist app; all I wanted was a notepad that locks. Well I'm just gunna go ahead and delete that other one, seeing this one does... everything. Notepad, checklist, calendar- and the interface is simple. All locked behind my pattern lock- though I could also choose a pin or password. And if I forget that password (inevitably), I can just have it emailed back to me.

Now, the password only locks the app, not each individual note. Be careful about leaving it open- a savvy kid could switch from your grocery list to Santa's toy list.

You can also choose a font, and enlarge or shrink the text size, but not for each note. This is fine by me, but worth mentioning. Each note can have a different color background, include pictures, be mailed to others- the works.

Over all, this is a great app. I highly recommend it.

-Oh. And by the way, the only "ad" was an option to upgrade to the paid version of this app. It only occurs if you try to use one of the extra features (such as cloud storage), but everything I already mentioned was in the free version.
