Our Products: 

The very first time the founders learned about computers they thought "We could use this for hunting!"  Thus began the long path to Ei-Sor Development.  We've kept a log of hunts in our camp for over 30 years.  While entertaining to read, the information was essentially useless for guiding our hunting activities.  The founders saw computer programs as the key to unlocking the value held in those logs and the first of a long line of electronic hunting logs was developed.  Over the past 30 years, new technology and ideas lead to many iterations of the e-hunting log.  However, these all had one significant problem that kept them from becoming very useful...data entry.  Data had to be moved from the log to the computer in a painstaking clerical task before any value could be created.  On top of this data wasn't always correctly entered or had missing pieces of data.  Even though the successive iterations made the product better and more powerful...we still didn't really use it.

Then came smartphones!  A mobile computer that could automate the capture of much of the relevant data and collect right at the source...when the deer was sighted or shot.  Ei-Sor Development was born!  The products described on this site represent the product of our years of experience hunting and fishing and in the computer industry.  We made these products for our use.  We use them in all our outdoor pursuits.  We hope you find them as useful and fun as we do.

The philosophy guiding all our mobile products is that data collection should be as easy as possible so that all you need to do is click a button.  The apps collect weather, location and time/date  automatically. Some of the apps require some preliminary setting so that the data collection is just a button click.  These settings can be done before hunting or fishing. 

Not one of our products gives us access to any of your hunting or fishing data!  We can't tell you the best place to hunt or what is biting because we don't collect any of this information from anyone.  Your data is not shared with anyone unless you choose to do so.  We also do not collect any other information from your phone.  Our only revenue comes from the purchase of the app.
