IPPT Buddy
Read full descriptionHide full description
From 1 Sep 2014, the SAF will launch a pilot implementation of a new and simpler Individual Physical Proficiency Test (IPPT) format, which will be accompanied by a new scoring system. The new IPPT is expected to be fully implemented across the SAF in 2015. Like any newly introduced system, there is bound to be some learning curve. This simple yet user-friendly app hopes to make the transition to the new system as smooth and painless as possible. Features include: 1. Auto calculation of awards requirements based on your NS status and vocation. This will be regularly updated to support more criteria once more details are released. 2. Auto calculation of total points with breakdown of points for individual station and award achieved. 3. Auto saving of all keyed data for convenience. More features coming soon… :) All feedback and suggestions are welcome.
