Export PacketCalc’s data in several formats, including Text, JSON, and Soulver. Soulver is an app that runs on iPhone, iPad, and Mac that has a unique approach to calculation that’s somewhere between a calculator and a spreadsheet. Copying PacketCalc’s internal data to Soulver allows you to perform calculations like determining the percent overhead of all packet headers.

You can also copy a single Tile’s data to the Clipboard as Text (by double-tapping the tile), or as Text, JSON, or Soulver (by long-touching the Tile).

Adaptable Text

PacketCalc’s UI honors iPhone and iPad system text size settings. If the font isn’t big enough, you can change it as follows:

1. Launch the Settings App

2. Tap Control Center

3. Tap Customize Controls

4. Ensure Text Size is enabled

5. Exit the Settings App

6. Launch Control Center by swiping down from the Top Right of your home screen

7. Tap the tile with the small and large A’s.

8. Adjust as desired.

9. In PacketCalc, the text has changed to match
