NX Activity Log is a homebrew application that reads and displays the amount of information about our play activity that we should have been given on the User Page.

The UI has been designed to feel familiar and is navigated in a similar manner to the Switch's firmware.

Features

• Viewing Play Activity (per user)
  • All Time Activity:
    • Total Playtime in minutes.
    • Number of times a game has been launched.
  • Date of first launch:
    • Date/time of most recent launch.
    • Average time spent in a game.
    • Sorting games by time played, recently played, etc..
  • Recent Activity (see note below).
    • Graph visualizing play time.
    • View by day, month or year.
    • Total playtime in seconds.
  • Number of launches:
    • Viewing each "Play Session".
  • Event-by-event breakdown of your activity.
• Multi-language Support
  • English, Chinese (Simplified and Traditional), French, German, Italian, Korean, Portugese, Russian, Spanish and Turkish.
• Theme Support
  • Automatic theme detection to match the Switch's colour scheme.
  • Custom Themes:
    • All colours used in the app can be adjusted.
    • Set a custom background image.
      • Requires a PNG saved at /config/NX-Activity-Log/background.png.
• Update in-app
  • Checks for updates automatically and displays an icon if one is available.
  • Update completely within the app.
• User Page Replacement
  • Requires LayeredFS and either Atmosphere 0.10.0+, ReiNX or SXOS (or build and copy the forwarder to your CFW-specific titles folder).
  • Requires .nro to be at /switch/NX-Activity-Log/NX-Activity-Log.nro.

Note: The data shown in Recent Activity and Details may be slightly inaccurate over larger periods of time (ie. off by a few minutes). If activity is not being shown for earlier periods of time it is likely your Switch has been reset at some point, which wipes the data used to calculate playtime in this way.

Installation

Place the .nro to the /switch/ folder on the SD card.

User guide

Exported JSON Format

All play data that can be read by NX-Activity-Log is included in the exported JSON (i.e. the system's data and any imported data).

The JSON has the following format

• exportString: Timestamp of export in human readable format.
• exportTimestamp: Timestamp of export in POSIX.
• exportVersion: Version of NX-Activity-Log that exported the data.
• users: Array of users on the system.
  • id: Unique ID of user.
  • name: Username of user.
  • titles: Array of titles played by the user.
    • events: Array of play events for the title by the user (see libnx/switchbrew for an explanation of these).
      • clockTimestamp: Timestamp in POSIX of event.
      • steadyTimestamp: Timestamp of a 'steady' clock, used to calculation duration between events as the clock may change.
      • type: Type of play event.
    • id: Unique ID of title (otherwise known as Title ID or Program ID).
    • name: Name of title (in system's locale).
    • summary: Object containing summary of play stats for the title by the user.
      • firstPlayed: Time in POSIX of first play.
      • lastPlayed: Time in POSIX of last play.
      • launches: Number of times the game was launched.
      • playtime: Playtime in seconds.

Reporting Incorrect Data

If you are seeing wildly incorrect values/believe the playtime shown is incorrect within Recent Activity or the Details screen, please do the following:

• Download and run the .nro from here.
• Leave it run; if it appears to be frozen leave it for up to a minute.
• Once it is done there should be a playlog.txt at the root of your SD card.
• Create an issue with the following:
  • Screenshots of the incorrect data (make sure the date/time and playtime are visible).
  • The playlog.txt acquired from the last steps.

Note: If the data shown under All Activity is incorrect, there is nothing that can be done. These values are read directly from the Switch and aren't the result of any calculations.

Controls

Hold ZL/ZR (when scrolling a long list) - Scroll faster

Screenshots

Known issues

• The main issue at the moment is that a few users' playtime is incorrect. This is due to the Switch being factory reset at some point and/or some games not requiring a user to be selected to play it.
• Having a lot of games logged can cause too much memory usage when launched via User Page/Album, leading to out of memory crashes and/or missing images/text.
• Having a lot of games logged causes a long pause/freeze when loading the "All Activity" screen.

  • This setting allows for the playtime shown in All Activity to be increased/decreased in order to make up for lost time, etc.

• The algorithm for counting play time has been slightly improved.

  • Almost all of the codebase has been rewritten.
  • The UI has been moved to my own UI library Aether.
    • This has fixed a few UI bugs and should make UI-related changes faster.
