What Others Say

“Opal, just like its Acta ancestor, is small, fast, friendly, effective and reliable. I’m using it to organize and manage everything from daily tasks to projects, and it works as a simple calendar/tickler and diary. I like to keep my main organizing outline on the desktop next to the hard drive, where I can instantly pop it open, review tasks and update information.” — Ric Ford

“Instantly responsive software, it is an absolute treat to use. … The software seems to meld away to the background and lets you concentrate on the task in hand, making outlines. It is very well-thought out software with a rich heritage which I am falling in love with. It definitely has found a place in my workflow.” — Mac OS X Guru

“I've never encountered a more precise, simple, useful tool for damn near anything that the human mind can imagine.” — Michael Milton

“Thank you for reviving this nifty software. This is what I have been waiting for since I switched to OS X. Opal is going to be an essential tool for me.” — Shigeaki Nishina

“I have refused to migrate to the Intel-based Macs, primarily because they won’t run Classic, and without Classic I can’t use Acta.” — Steve Eichel

“This is great software, and I can’t wait to buy a copy!” — Bill Shepherd

“Found this wonderful program a few weeks ago and have been using it daily since.” — Christopher Ridder Export dialog

“This is a gorgeous Mac OS X program. I’m particularly impressed by how you are enhancing the functionality by leveraging Apple’s Mac OS X APIs to the maximum: Services, text formatting features, spell checking, export capabilities including HTML output, and everything else.” — Wheat Williams

“Opal is a simple, flexible and useful outlining application which I suspect some people will end up not being able to live without.” — Chris Howard, Apple Matters

“After struggling for several days in the wilderness of Omnioutliner, Tinderbox and Taos, I discovered Opal. After thirty minutes exploring Opal I bought it. Great product and a good price. It’s intuitive, easy to use and explained carefully and clearly. Wonderful!” — Jim Sieyes

“Opal is great. It works like I ‘think’.” — Danny Harris

“Tried it. Love it. Bought it.” — Murray Battle

“I just downloaded Opal, and I instantly fell in love with it, because it is an easier-to-use version of OmniOutliner.” — Clint MacDonald

“The beauty of Opal is its simplicity. ... Thank you for resurrecting Acta! It is so nicely done.” — Doug Eddy

“I am absolutely and genuinely overwhelmed that you’ve revived this program. I’ve tried all others, such as OmniOutliner, and every word processor out there, and find them all way, way too bloated and far too difficult to mess with.” — Don
