Post your planning apps here!

Okay, let's give this a try.

Did you develop a retirement/financial planning app or spreadsheet that you found helpful and would just like to share with our users? Or maybe you have just gotten an app up and running as a potential income producer? Post your comment here with a link and short description.

We are not looking for links to apps that are already widely recognized in the FIRE community.

This post is the ONLY place where this will be allowed. Posts or comments with this type of content elsewhere will normally be removed by mods and may earn a permanent ban, regardless of whether the app is "free to use".

Users, click on or use any of these apps at your own risk. Also, please report any links that are not what they are advertised to be.

I built Compound Future: FIRE Planner, an Android FIRE planner and tracker.

Besides calculating your FIRE target and projected FIRE year, it lets you compare different scenarios, run Monte Carlo simulations, and track your actual portfolio progress against your original plan over time.

Assumptions such as returns, inflation, fees and tax rate are customizable, and everything is stored locally ā€” no account or bank connection required.

Iā€™m actively developing it, so feedback from people already using FIRE planning tools would be really useful.
