Want to join the global prayer movement? Operation World (OW), the definitive global prayer handbook, has been used by more than a million Christians to pray for the nations. Now as a mobile app you can receive reminders to pray for the “country of the day,” research statistics on each country and read the in-depth prayer request and praise reports given for each country of the world.

OW is widely regarded as the definitive volume of prayer information about the world and is the recipient of the ECPA Gold Medallion Award for Excellence in Evangelical Christian Literature.

OW has had seven editions published. The most recent is from 2010, which is a complete update of the 21st century edition, released in 2001. The previous edition was published in 1993. The original edition was produced in 1964, from South Africa, and was only 32 pages of basic information about 30 countries.

OW has been translated into several other languages: German, Spanish, Portuguese, French, Korean, Chinese, Russian, and in part into Indonesian and Italian. The cumulative number of copies printed in all languages exceeds 2 million. The 7th edition was released in October of 2010.

OW listed in Christianity Today's The Top 50 Books That Have Shaped Evangelicals, Landmark titles that changed the way we think, talk, witness, worship, and live.

Informative prayer app

It gives a concise presentation of the nation to pray for - the people, statistics, sociopolitical situation and prayer needs.

The one thing I don’t like is the continually changing images at the top of the screen. These are very distracting when reading the text below them. One cycle through the three images would be enough, with the option to manually swipe through them as desired.

Thank you so much for the suggestion and your prayer. We will look into ways to make the slideshow less distracting.

Informative and concise prayer app

Great information and prayer points are available for every country. This app not only has great content but works well. I’ve been using the app since January and haven’t experienced any bugs or freezes.

I do have some questions about how up to date all of the information is, but world situations can change quickly.

Thank you so much!

I love this app

This app really helps me know how to pray for people around the world. Reading about some of these nations and their struggles breaks my heart, which forces me to my knees in prayer.

One thing isn’t working, which is the I’m Praying button. Well, it seems to click, but the number always remains at 0.

Edited after developer response: Uninstalling and reinstalling fixed the problem! Thank you.
