bullet"I was going to toss my new Blackjack II until I found your Agenda app!  So much better that the default calendar application, thanks guys!" - Fr. Nicholson
bullet"Agenda One is simple and does the job magnificently. Thanks." - Rob R
bullet"I'm a big fan of David Allen's 'Getting Things Done' and your Agenda One is the closest thing I've found that really helps me follow this time management approach." - Gerry N.
bulletRating: 5 out of 5
One line summary: "Highly productive and clear calendar."  "I have used several Windows Mobile calendars.  Agenda One is the most functional, straight forward, intuitive, cleanly designed calendar software with many thought through features." - Akos
bullet"Thanks for listening to my suggestions!  But I have to tell you, what Agenda One does for me for managing my time is equivalent to what the iPod does for me to make listening to music easy!  The interface delivers that same quick, intuitive operation that I've become use to on my iPod.  I can't imagine ever going back to using the built-in applications on my phone." - Carlton G.
bullet"In comparing your Agenda One to applications like Pocket Informant and Papyrus, what clearly stands out is the huge difference in ease of use with Agenda One.  The level to which you've simplified the use on my phone is fantastic...  I'm happy to be a customer and excited to see what you'll be doing in the future." - Phillip T.
bullet"Thanks for an application that really keeps things simple!  I had been using Xtreme Agenda for the last several months.  When they decided to start adding a lot of 'fluff', I had to look elsewhere.  Your Agenda One really meets the need of keeping everything simple.  Thanks again!" - Sarah E.
bullet"What you have done here is nothing short of outstanding.  I honestly didn't think anyone could create such an application for the Smartphone that would be so simple to use.  If you had only the month view I'd still be sold.  - Stan R.
bullet"Thanks for the preview of Agenda One.  We've been long looking for an enhanced time management solution to bundle with our devices.  Our marketing group tried out Agenda One and was sold on the idea within minutes of trying it out.  The interface for changing options is really something.  I hope you'll be offering it for the Pocket PC soon as I see some great opportunities there as well...."
- Wireless carrier
bullet"I've been waiting this for a while and I tell you it was so worth it!!!  I've been using two other programs for my Motorola Q that combined, cost more, did far less and were so clumsy to use, well enough on that, those apps are gone from my Q now!  Agenda One rocks!" - Taylor J.
bullet"I just received my T-Mobile Dash and was looking around for software and came upon your AgendaOne,  Just wonderful.  I tried another time program and gave up on it within the hour after fighting to figure it out.  A couple of moments of trying your software it seemed to just fit into my Dash perfectly.  I can't wait to play with this some more!" - Connor L.
bullet"Hmm, my first reaction is: Impressive!  I use it on my Palm 750v although a stylus is present itís very handy with that one hand navigation. Good looking interface too! Nice colors and a clear overall look! A welcome app!" - David W.
bullet"Thank you so much!  It is very obvious the time put into program as it loads flawlessly and the features are spot on and the GUI is again the best I have ever seen!" - Doreen C.
bullet"Brilliant! The Best PIM on the Market!

What's the problem with lots of the Pocket PC PIM's on the market? Well, you can do so many things to your tasks, you spend your life organising your lists, rather than acting on them. Agenda One recognises that the point of a PIM is to present data quickly and comprehensively. And that in order to be more efficient than paper, you have to be able to get information into/out of it quickly!

It's fast, looks great, is powerful enough to manage complex task lists, and is amazingly easy to use. Perfect Product!" - Dan S

bullet"WWOWW!! Finally a top-shelf program for "Q"...  Very Nice - I'll be upgrading this weekend."
- Peter W.
bullet"Your update to the contacts is awesome!  I have over 3000 contacts on my Moto Q and the stock contact program was so so slow.  This is good stuff!  Like the name of the movie, I now have "Happy Feet"!" - Frank W.
bullet"I just had to write you.  I was long a Pocket Informant user and just tried out their Pocket Informant 8 version.  After experiencing just how bloated their software is, I started looking for alternatives.  I found you guys and have to say that your Agenda1 is a breath of fresh air, works nice and simple and meets my needs just perfectly.  You have one happy new customer!  Thanks!" - William R.
