No more writing everything down on a pieces of paper to be lost in your range bag. When your friends ask about the loads you are using, you can pull out Chronograph Log and give them accurate info instead of guessing. Send them an email or message on the spot. Share your favorite loads via eMail, Facebook and more. Chronograph Log was primarily developed for USPSA IPSC and IDPA, where Minor and Major Power Factors are very important. It will color code those entries based on their velocities. Note that the Power Factors can be ignored if you are tracking rifle loads or don’t care about Power Factors. Note: This application is not a chronograph. You will need to enter readings from your chronograph into the Chronograph Log app. • Define: Bullets, Guns and Powder in the database. • Record velocities for each round from your chronograph. • Automatically calculate Average, Min and Max velocities. • Color coding to show each velocity’s Power Factor. • Export full tables to Mail. • Export favorite loads to Messages, Mail, Twitter or Facebook. • Backup / Restore to Dropbox. • Bluetooth integration with Competition Electronics "ProChrono Digital" using their "Digital Link" module. ## Chronograph Log Screenshots - [Screenshot 1](https://is1-ssl.mzstatic.com/image/thumb/Purple211/v4/56/07/20/560720c7-7066-5740-1307-70f353c9d8a7/mzl.dhwivwja.png/640x960.png) - [Screenshot 2](https://is1-ssl.mzstatic.com/image/thumb/Purple211/v4/a3/da/31/a3da3183-0467-5140-3a2f-1f1070e0a8e4/mzl.eujhmvrf.png/640x960.png) - [Screenshot 3](https://is1-ssl.mzstatic.com/image/thumb/Purple221/v4/49/a8/84/49a88494-568d-285f-8736-04bfaa7110bc/mzl.nhmqjgmt.png/640x960.png) - [Screenshot 4](https://is1-ssl.mzstatic.com/image/thumb/Purple211/v4/15/fc/2a/15fc2a13-b5a8-8713-07c9-be4d199c84c2/mzl.wihhgvmg.png/640x960.png) - [Screenshot 5](https://is1-ssl.mzstatic.com/image/thumb/Purple221/v4/b2/f1/e3/b2f1e31c-221b-948e-b3ba-601f151e3d3f/mzl.qsdlgitx.png/640x960.png) ## Chronograph Log Rating Breakdown in United States - 5 stars: 1 (33%) - 4 stars: 1 (33%) - 3 stars: 1 (33%) - 2 stars: 0 (0%) - 1 stars: 0 (0%) ## Chronograph Log Reviews in United States ### ****- "Very useful and powerful" Love this app. Entering data was very simple and the results are very easy to understand. Well designed to handle multiple loads, guns, bullets, powders, etc. I wish the major/minor PF was an option though. I just entered "1" for rifle loading. Capturing data from a factory load is kind of clunky as well - I don't know the powder charge or type, but those are required. I linked my dropbox acct but I couldn't export anything to it. All around a very useful app to pair with a good chronograph. -- taylorjr.cns13, 2014-08-16 ### ***-- "Not bad" Simple to use. Pretty basic. I would like to see average muzzle energy added. This is primarily a computer to determine if a load makes power factor. $3.99 is a bit much for this one but it is the only one I could find. For this price I would expect ME calculation and possibly some graphs. The ability to turn off calculations not needed would be nice too. -- flyingrhino, 2014-07-14 ### ***** "Must have for any Chronograph Owner" I shoot several different calibers of pistols (.38 Special, 9mm, .40 S&W and .45 ACP) and normally write down the chronograph information on whatever scrap of paper I can find at the time which of course always gets lost between the range and the trip home. Now I use either my iPhone or iPad and log the chronograph runs and never have to worry about losing the data again. Being able to sync the chronograph data between my iPhone and iPad means I always have the data available and can share it with friends by exporting the chronograph data via email. Thanks for writing such a handy application! -- ZackOJones, 2014-06-09 [View all Chronograph Log reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## Chronograph Log Store Rankings | Chart | Country | Category | Rank | |-------|---------|----------|------| | Top Paid | Azerbaijan | Sports | #69 | | Top Paid | Kazakhstan | Sports | #93 | | Top Paid | Philippines | Sports | #115 | | Top Paid | Lebanon | Sports | #132 | | Top Paid | Indonesia | Sports | #159 | | Top Paid | South Africa | Sports | #175 | | Top Paid | Chile | Sports | #179 | | Top Paid | Saudi Arabia | Sports | #182 | | Top Paid | Brazil | Sports | #203 | | Top Paid | Thailand | Sports | #225 | | Top Paid | Finland | Sports | #233 | ## Chronograph Log Discovered Keywords -
