Polar Flow Export

Bookmarklet for exporting your Polar Flow data.

Installation

Create a bookmark with following content:

javascript:(function(){!function(){function e(e){$("#polar-flow-export").remove();var t=$('<div id="polar-flow-export"></div>');t.css({position:"fixed",width:"100%",height:"100%",top:0,left:0,zIndex:9999,background:"white",padding:"0 40px",boxSizing:"border-box"}).appendTo($("body")),$("<h1>Export Polar flow data</h2>").val("foobar").appendTo(t),e?($("<p>You may now copy-paste the information below to a spreadsheet program (such as Excel or Google Spreadsheet).</p>").appendTo(t),$("<textarea></textarea>").css({width:"100%",height:300}).val(e).appendTo(t)):$("<img />").attr("src","http://cdnjs.cloudflare.com/ajax/libs/galleriffic/2.0.1/css/loader.gif").appendTo(t),$("<br/>").appendTo(t);var o="https://github.com/Pyppe/polar-flow-export";$('<p>See <a href="'+o+'" target="_blank">'+o+"</a> for more details about this bookmarklet.</p>").appendTo(t).find("a").css({color:"#d10027"}),$('<button class="button" type="button">Close</button>').css({fontSize:"20px"}).click(function(){t.remove()}).appendTo(t)}function t(e){function t(e){return("00"+e).slice(-2)}var o=/(\d+) hours?

Why, oh why?

Because the UI of Polar Flow doesn't give you very good summary views. Exporting data in tabular form gives you the freedom to create graphs that are relevant to you. For example, this graph shows that I probably should sleep more during weekdays...
