Journler is now open source at GitHub. As a result, developer Philip Dow is no longer actively supporting Journler. The latest version, 2.6.4b, is stable on my Mini under OSX 10.7.3. OTOH Dow has been working on a smaller daily diary app called Per Se that works pretty well. It just has fewer features than Journler. Go to his site for explanations and FAQs and downloads.

To update some of the comments below, I thought I should make some new ones. I'm using OSX 10.6.8 now after using 10.6.7 and all versions back to early 2006 when I converted to Journler. I have encountered no difficulties, and there are multiple export opportunities in Journler (many outputs in many formats). They do work well to my own experience. I converted to Journler after starting a journal in Daily Journal for Windows on May 5, 1994, and have made entries just about daily ever since. I converted to MacJournal (importing my Daily Journal entries in RTF) in about 2001 while it was still free, but exported everything out to Journler in RTF after MacJournal sold out because I could see it heading for the expensive bloatware it's become. As of today, I have 7,371 entries in 18 annual folders in Journler, including a number of links and some pictures, and it continues to work like a charm. In fact, it works so well, is so easy to search, and is so important to me that I am delaying installing Lion on my MacBook Pro (or even buying a new Mac) until I know that Journler works well on Lion. I don't like to mess with success, and Journler has definitely been that for me. This is the last and longest lived of my critical softwares to update--and to me it is absolutely worth the wait. I too have tried all the journaling apps, and this is the best when you get into the kind of volume I deal with. Anything can do 200 entries. A lot fewer are reliable with 5,000 or more.

Unfortunately, Journler now crashes immediately on launch ever since I installed the 10.6.7 Mac upgrade.

I assume this is a problem others are having as well, but I can’t find any answers on the web no matter what I do.

The Journler forum is so overrun with spam, I can't tell if anyone ever answered my complaint. An email to the developer Phil Dow is still unanswered.

This is one of the best journaling apps ever made (and I've tried them all), but it now is supposed to be open-source, but really appears to becoming abandonware.

The thought of losing my 569 irreplaceable entries in frightening. The data files are in a quirky .jrtfd format, and apparently can't be exported to any other journaling app.

I’ve already been through this when having to previously abandon MacJournal and maybe even one other diary app before that!

For this reason, I have to rate its stability as .05.

As previously noted, Journler was and is a free application. It's development stopped BEFORE it's license changed to shareware. The MU admins should change this listing back to it's proper free license category, so that people coming across it do not get the wrong impression.

Once again, Journler 2.5.5 is a FREE application. It is NOT shareware.

It was a nice app, beautifully done, but make sure to note that the prices were for the 2.6 prebuy; 2.6 will never come, and I'll use it until it hits a snag with OS updates, with my 10$ personal use donation, but I'm sorry I don't see why people would have to pay the price of something that will not be. It's a bit like buying some land on the moon for now.
