For US Government Employees or Retirees, military or federal, who would like: to get an alert when a Thrift Savings Plan (TSP) fund changes by a determined amount, to quickly examine the Thrift Savings Plan (TSP) past performance, to easily track their current investments, to quickly make reasonable estimates of how much must be saved in an investment to yield a target amount, and to easily estimate how much a given investment will yield at a future date, without accessing the TSP website or exposing any personal information to the internet. All data entered into this app is kept contained on your device. This app does not send any TSP data that you add to it to any central entity. This app does not require your TSP account information nor is there any way to store your account access details into the app. To set an alert select a fund from the alert screen. Examine the graphs at the bottom of the screen by touching Days, Weeks, or Months. Select from “Previous Day”, “A Week Ago”, and “A Month Ago”. Set a percentage from 0.25% increments. Once set, the funds status will be on the “Alert” screen. The alert for this fund will be "on" or the alert will have text in red for negative or text in green for positive results. To see how much you would have in the C-Fund if you had invested $100 per pay period since the beginning of the TSP program you simply press the “+” button on the “Track” screen and enter a Portfolio Name, then tap the "+" button and select add investment, pick “C-Fund” and create the investment, tap "+" to add a contribution. Add the amount ($100) and select “BiWeekly" frequency select the date field under “Recurring Investment” and choose May 31 2003, then press “Save”. The answer will be displayed on the “Track” screen. If you use "Track" for your investments assure the dates match those where contributions are made.
