A Prayer Journal. Keep a running list of topics that you are praying about, along with a series of entries (thoughts, specific prayers) related to each topic. Share entries or the entire Journal with friends, using Email or SMS text messaging. Set alarms (notifications) to remind you to pray for the topic (one-time, or repeating) with a different notification sound for each prayer request. Upload your Journal to Google Docs. When you feel you have reached an answer to your prayer topic(s), mark them as Answered and keep them available for later viewing, to remind yourself of God's goodness to you in those requests.
