Available ports (and non-ports) for unsupported platforms

If a program is derived from XTide source code, I call it a port, even if there are significant changes, code added and code deleted.  If a program contains no XTide source code but can use the same harmonics files that some version of XTide did, I call it a non-port.  These are only listed if there is no good port to a given platform.  This is not an attempt to track all tide-predicting software, only that with some commonality with XTide.  Better software having nothing to do with XTide may be available, but is not listed here.

These programs are all maintained by different people.  They may be significantly different from XTide 2 as documented here.  If you have problems with a port or non-port, please contact the correct maintainer.  I cannot help with anything but the canonical Unix distribution.


Android screenshot   2015-01:  Will Kamp has produced a GPL port of XTide 2.14 to Android.  The libxtide bit is separate from the user interface, and although it is close to stock it was rearranged somehow to work with the Android NDK build system.  Source code is available at the preceding links; the MX Tides app is available from Google Play.


2013-10:  An iOS version of MX Tides from Will Kamp is on github and pending for the app store.


2013-06:  Selene Associates LLC did a port of XTide 2.12.1 to iOS (phone or tablet), called EyeTide.  The binary is available through the Apple app store; sources can be obtained from http://www.selene-associates.com/downloads/eye-tide/.


Michael Parlee did a port of XTide 2.10 to the iPhone, called ShralpTide2.  The binary is available through the Apple app store; sources can be obtained from http://github.com/shralpmeister/shralptide2.

An older ShralpTide port based on XTide 1.6.2 is also available.


You don't need to use a port:  See the installation instructions for details.

Microsoft Windows

You don't need to use a port:  XTide can be compiled and run using Cygwin, which is an emulated Unix environment for Windows that is free for typical non-commercial users.  The Cygwin distribution and its full license terms are available from http://www.cygwin.com/.  Please refer to the Installation section for special instructions about using XTide under Cygwin.  Alternately, you could run a Linux virtual machine.

Native DOS and Windows binaries for the command-line client tide are available under contrib files and can be built as described in the Installation section.

The following native ports of the graphical client were done:



2016-07:  R is not an OS platform but a software environment for statistical computing and graphics.  Joe Thorley and Luke Miller have produced rtide based on XTide's sources and harmonics data and made it available under GPL3.  It is hosted at https://github.com/poissonconsulting/rtide.

Maemo (GTK)

From http://maemo.org/intro/:  "Maemo is a software platform that is mostly based on open source code and powers mobile devices such as the Nokia N810 Internet Tablet.  Maemo platform has been developed by Nokia in collaboration with many open source projects such as the Linux kernel, Debian, GNOME, and many more."

GTKTide by Mike Morrison is a fork of XTide 2.10 and libtcd with a GTK-based user interface, intended for use with Maemo.  As of 2009-03-04, the last revision was in 2008-11 (source revision trunk-r7).  GTKTide is available from http://maemo.org/downloads/product/OS2008/gtktide/.

GTKTide can be compiled and run under desktop Linux, though not necessarily with ease.  Under Slackware 12.2, the build scripts did not configure dependencies correctly, and it took a long line of CPPFLAGS and LDFLAGS to make it go.

The GTK interface performs well for the common use case of viewing the tide graph for a specified location, but the controls needed to engage other modes of operation and to tweak XTide settings are absent.



Walt Bilofsky implemented Tide Tool for the Palm Pilot or any other compatible device running PalmOS.  Bilofsky wrote: "Tide Tool used to qualify as a port, and still has a modest amount of code from XTide 1.5.  But since Jeff Dairiki redid the algorithm to use integer math, I'm not sure how much of it is XTide any more.  I guess I'd call it the descendant of a port."

Pocket PC / Windows CE


Dave Buchholz implemented cTide for the PocketPC 2000 or PocketPC 2002.  It's a port of a port (WXTide32), but the screenshots still look a lot like XTide.  You can find it at http://airtaxi.net/ctide/.

J2ME (cell phone)

Nokia phone with muTide  

Jörn Eichler implemented an XTide-derivative called µTide for the J2ME platform.  It is designed for modern smart phones like the Nokia N series, which have decent performance at floating-point math.  It used to be at http://www.tj-eichler.de/muTide/; as of 2016-01 this URL has been redirected to advertising.

Timex Datalink USB

Timex Datalink with DTide

Paulo Marques implemented DTide for the Timex Datalink USB wristwatch.  It uses a patched version of WXTide32 on the PC to allow the user to select locations and prepare simplified harmonics data to feed the application on the watch.  It can store more than 200 (simplified) locations in the watch's memory.  The application on the watch is an assembly language non-port using only integer math.

To get the application, download TreeBrowser_vX.zip and Tree Browser Feeders/DTide.zip from the Files > WristApps archive of Yahoo Group timexdatalinkusb.

To get the source (TreeBrowser asm and patch against WXTide32), download TreeBrowser_src.zip and DTide_src.zip from the Files > WristApps archive of Yahoo Group timexdatalinkusbdevelop.

HP Calculator

HP Calculator  

David MacCuish and Dennis Straley did a similar-in-spirit non-port for HP48G and HP49G series calculators.  As of 2011-08-28, the original HpTide site at http://heygus.2y.net/hptide is gone, but version 0.3.2 (2001-11-11) is archived at http://www.hpcalc.org/details.php?id=3943.
