Some of you may have already noticed: Since yesterday, the Portfolio Performance App is available both on the Apple App Store and on Google Play Store.
Check out some screenshots here:
For the curious ones: The app was developed using Flutter. This allows me to support both iPhone and Android with a single codebase. So far, the source code comprises about 41,000 lines. Similar to the desktop version, I plan to gradually develop the app further.
How does the app work?
Store your file in binary format on a cloud storage service, e.g., iCloud, Google Drive, OneDrive, and then open it on your iPhone or Android.
You cannot (yet) make changes in the app - the app is a mobile companion to the desktop application. In addition to the desktop dashboards, you can create and edit your “mobile dashboard” on the go. All calculations are performed solely on your device - the larger and more complex your file, the more computing power your phone should have.
Does the app cost anything?
Most of the app is free: the statement of assets, performance calculation, the charts, the statement of earnings (dividends, interest), the classifications with rebalancing data, updating of prices and exchange rates, etc.
However, using the dashboards requires a subscription. I opted for a subscription model because an app needs continuous updates, e.g., updates to new operating system versions, adjustments to price sources, etc. With one-time payments, many apps wait to release updates for major releases or focus on new gimmicks instead of improving core functions. To make a comparison that might be used too often: it costs less per month than a coffee.
If you contribute to Portfolio Performance (whether through source code, translations, documentation, testing, or in the forum), then you can get a one-year subscription for free. Please send me an email at support@portfolio-performance.app with your GitHub, POEditor, and/or forum name, whether you have an iPhone or Android device, and the user ID from the diagnostics page in the app.
