I wanted to play a simple app to calculate an arbitrary value in terms of point-in-time purchasing power and real value. I also wanted a simple visualization of these calculation over time.


Feel free to use flation at your leisure for whatever purpose you have in mind.

Future Versions

flation is currently free to download and use. At some future point, flation may become a paid-up-front app. When this transition occurs, a purchase will be required for continued use of flation.


All flation purchases are final. I cannot issue refunds charged to your Apple ID, but you can ask Apple to do so.

For Reference Only

flation is not intended for, and should not be used for future-looking purchase power or real value.


Data Collection

flation does not collect any data.

Data Sharing

Given the above point, flation cannot share data. flation is a SwiftUI app and makes use of Apple’s developer libraries exclusively; no external libraries. These Apple libraries do not, to the best of my knowledge, collect data.

Data Retention

Since flation does not collect data, flation cannot retain data.


There’s not much that can go wrong with flation. That said, if after restarting your device and reproducing the issue you think you’ve found a bug, please reach out; I don’t like bugs either.
