ChangedCPI data is downloaded directly from BLS on demand rather than baked into the app, so new months arrive with a pull-to-refresh or the daily check instead of waiting for an app update.
AddedEvery CPI series with its full history, for both populations (CPI-U and CPI-W); All items, U.S. city average goes back to 1913. Optional Regional and Category data subsets.
AddedCompare Series to see how two or more series trend over the same dates, in absolute terms or relative to their average or a chosen base series.
AddedTrack Monies to see how historical monies (like salary or rent) trend over time, as Purchase Power, Nominal, or Real Value. Sets export to CSV; with Pro, they import too.
AddedBrowse Series to search and filter through over 12,000 active series by name, ID, population, seasonal adjustment, period, area, and item. Each series has a detail page with its trend, year-over-year change, and a link to FRED.
AddedFavorite series, synced through iCloud so they survive a reinstall and follow you between devices.
AddedA Saved library for conversions, comparisons, and tracker sets. Saved items can end at the latest data, and a Rolling Window keeps "the last five years" current as new months are released.
AddedAny chart can be shared as a PNG image.
AddedRecession shading from the National Bureau of Economic Research's business cycle dates (Pro).
AddedA native Mac app, with a sidebar for Convert, Compare, Track, Browse, and Settings.
ChangedChart Range replaces the chart padding options; pin either edge of a chart to the start or end of the series and pad the free edge with a slider.
ChangedThe percent capsule on Convert now says what it measures; cumulative inflation or deflation on Purchase Power, loss or gain on Real Value.
ChangedApp icon.
ChangedNew features are gated under an annual Pro subscription; existing customers are grandfathered into lifetime Pro with no additional charges. Free users keep the four All items, U.S. city average series, their last five years, and one example each of a conversion, a comparison, and a tracker set.
FixedMonth-over-month and year-over-year changes were calculated by row offset, which assumed a gapless monthly series; the missing October 2025 shifted every later comparison to the wrong month. They're now matched by calendar date.
FixedPicking a month that has no CPI data (October 2025) substitutes the prior month and shows an alert explaining why, instead of using the wrong observation.
AddedExtended CPI through November 2025. There is no October 2025 figure; BLS could not collect it during the federal government shutdown.
