It would get five stars if it had information from at least the 1800s, but ideally to 1776. Other than that, I recommend this app. ### 5/5 — Woo Hoo. It Updated!!!! *2024-05-07, version 1.1.8* Had been running the 2019 version and now that this puppy has been brought current you can keep track of just what kind of number this lame Biden presidency is doing to the value of your moolah. (LET’S GO BRANDON) - - - Oct 21 - - - ### 5/5 — Simple, easy to use, trust worthy source *2024-03-06, version 1.1.8* And prior reviews complained that it wasn’t being updated often but it seems that the 2023 CPI info was added in Feb 2024, which is pretty good since they have to wait for the year to end and do final calculations to have that year’s official CPI. ### 2/5 — Update for 2024 please *2024-02-25, version 1.1.7* The website uses up to date calculations, why not the app? ### 4/5 — Useful BUT Needs To Be Updated *2024-02-04, version 1.1.7* Only goes to 2022. This us 2024. Please update. It’s a great app and very useful. PLEASE UPDATE. ### 5/5 — Woo Hoo. It Updated!!!! *2021-10-31, version 1.1.6* Had been running the 2019 version and now that this puppy has been brought current you can keep track of just what kind of number this lame Biden presidency is doing to the value of your moolah. (LET’S GO BRANDON) - - - Oct 21 - - - ### 5/5 — Simple *2021-06-08, version 1.1.5* Great app that just works. It has one specific function of calculating inflation and that's all I need. ### 3/5 — Needs an update *2021-05-28, version 1.1.4* As of now the app only calculates up to 2019 so accuracy is a bit of an issue. ### 4/5 — Very useful tool *2021-05-23, version 1.1.4* I use this quite often. The only reason I didn’t give five stars is that it only goes up to 2019, and I would think 2020 data is available now (end of May 2021. ### 1/5 — UPDATE NEEDED *2021-05-09, version 1.1.4* Good app but desperately needs an update ! ## Frequently asked questions about What is a Dollar Worth? ### What does this app do?
