13:20:Sync App Reviews

Good app. Not very user friendly (hidden functionalities). All my contact birthdays are shifted 1 day forward (22th nov instead of 21th for example). Please fix this bug. Thx

It is sad when you buy an app and it do not work. I restart my iphone4 running iOS 4.1 and did not help. It crashes in a few seconds.

Great way to learn! Thanks

Wonder app! The best one to learn about the mayan cycles and the peace calendar! Helpful, beautiful and full of information!

beautiful :) thanks for making this helpful app! it is an adventure to explore the mayan calender and realize the many syncronizities in daily life by simply learning about the 13 tones and 20 seals.. please keep on developing.. i love it!!!!!

Very nice app... hope it will continue to add features! Thx!

thank you so much!

Very cool app... Simple yet usefull

I love it! The only inconvenient is you cant put too many contacts birthdays otherwise it doesnt open anymore.

I am new to the 13:20 system of time. This has really helped me along with understanding the system better. Love the detailed explanations of the seals and tones. Looking forward to more features.

Before this app my consciousness of the 13:20 whirl was sporadic... Now I am actually living it and making the connections because I have the ability to check the day while I am on the go. It could use more features like being able to see more easily which days on the gregorian calendar fell on which 13:20 days but for the price I am super happy. Thank you Emmanuel <3

Thank you for making this practical & easy to use app!

Have had this App since December 2012. I try to check it every day but doesnt always happen. Its intriguing and complex to get my head around the concepts. However, I enjoy reading from the site and bought one of Jose Arguelles books. Its fascinating , and Im planning to learn more.

By far the best 13:20 app Ive used.

Its pretty good, but I would like to have the ability to use it as a calendar so that I could list appointments and so on. Also it would be nice to be able to make notes to correlate events that happened according to the Dreamspell codes.

Great way to keep track of birth kin of friends and family. The Time Vector Potential function is a nice addition.

Beautifully articulated, brilliantly conceived. I met its creator, Jose Arguelles, at the Prophets Conference in Vancouver a few months before he passed in Feb. 2011. He shared his vision of forming a twin rainbow through the axis of the earth and around the planet, as a manifestation of the One Mind of humanity. Hugging him was like hugging a cloud. He did not get to experience 2012 from this side, but he personally handed me this calendar as a small pamphlet. Wonderful to use it now in app form.

This is the best app, what I had on Mayans theme!!! Thanks!!!

Very powerful mayan calendar, you have all that you need!

Guys, I was living with Tzolkin several years and now a bit disappointed. How 29 Feb. and 1 Mar. 2015 can be the same kin? Please advise. Kind regards, Ivan
