CompArea is available in the App Store; Eye Tide update in the works

Our newest app, CompArea, is now available for the iPad in the App Store. CompArea allows you to compare the size of two geographic areas or features by displaying side-by-side maps synchronized to identical scales. We developed the app to satisfy a need of our own; we're hoping others will find it as fun and useful as we did.

We also have some interesting enhancements on our "to do" list.

We're also enhancing our Eye Tide iOS app to address requests and criticisms from early users of the app:

  • Eye Tide gets its prediction values from a set of "stations" for which NOAA generates the necessary data for the predictions. Users interested in specific beaches or areas not represented in the NOAA data have found it unwieldy for finding predictions of interest. We're making it easier to find the stations closest to a location of interest, which should provide useful predictions.
  • We're adding weather prediction data from the National Weather Service, which will provide better predictions for water levels (via predicted wave heights) and beach and boating conditions.



New app coming soon

We have a new iPad app under development that we hope to release in a few weeks. We wrote it to provide visual answers to questions we've asked ourselves on occasion over many years, but have never had a convenient resource to go to. Now we do, and we hope to put it in your hands soon. 

It won't be world-changing, but we're having fun with it, and hope others will, too.


Eye Tide update (v1.0.1) is in the App Store

An update to our tide prediction app, Eye Tide v1.0.1, is now available in the App Store.


  • Fix initial orientation problem on iPhone
  • Fix overlapping labels and tables
  • Disable meaningless selection in table views
  • "About…" pages better formatted for iPad
  • Modest improvements to location selection UI
  • Display current time correctly for location's time zone
  • Add map to empty space on station tab (portrait)

We have many more improvements in mind, including significant improvements to the chart view: better date range selection, better rendering, eliminating display glitches, etc., plus lots more. There's probably more work on our to-do list than was expended on the initial release.

At the risk of spreading ourselves too thin, we have another app in development: it's a tool that allows us to answer questions that have piqued our curiosity over the years, and we're hoping others will find it useful, too. As it turns out, iOS makes it easier to address these questions than it has ever been, so we're hoping to create some meaningful value with relatively little development effort. Stay tuned.



Eye Tide is available on the iTunes App Store

Our first iOS application, Eye Tide, is now available on the iTunes App Store. Eye Tide provides tide predictions, as well as sun/moon rise/set times, for hundreds of locations around the USA, rendered as tables and charts.

We have a long list of improvements in mind for iTide, and we're interested in ideas and suggestions; please feel free to contact us.

Eye Tides is based on David Flater's XTide v2.12.1, which is available under the GNU Public License. Under that license, we are obliged to provide the source to Eye Tide, which will be available on this site soon.


Starting up...

We have an app more or less ready for the App Store, and we're working on dotting and crossing all the i's and t's necessary to get the app submitted and accepted. It's reportedly an arduous process, and we're at the beginning of the learning curve. Stay tuned...
