Obstino app for iPhone and iPad

From Latin dictionary: "Obstino - be determined on". Not your average "dont break the chain" app. Obstino is a simple but unique motivational tool and visual diary of your progress. How it works:

* You set a few goals.
* For each goal you artistically mark off the day on which you worked toward that goal, expressing yourself and visualizing your efforts and feelings.
* After a while you have a few beautiful calendars with your unique drawings, not standard soulless marks.
* You can review any day from the past and see your custom drawing from that day in all its glory.

Features:
* Clean and simple UI which doesnt distract you.
* As many goals as you need (up to 2 goals in standard version, unlimited goals via in-app purchase).
* Option to count weekends as part of the particular chain or not.
* App badge shows number of unmarked goals for today.
* "Grace period" - you can mark off a few days in the past (see pencil icon).
* Double tap draws perfect machine-generated mark.
* Shake phone to erase drawing.


What is the "dont break the chain" method? As Jerry Seinfeld describes (http://lifehacker.com/281626/jerry-seinfelds-productivity-secret):
"For each day that I do my task of writing, I get to put a big red X over that day. After a few days youll have a chain. Just keep at it and the chain will grow longer every day. Youll like seeing that chain, especially when you get a few weeks under your belt. Your only job next is to not break the chain."
