Arknights: Endfield Playtime Tracker vs GameDiary

Arknights: Endfield Playtime Tracker records playtime automatically by checking every five seconds whether Endfield.exe is running. Its browser dashboard at 127.0.0.1:27182 shows a live timer, session history and a NOW PLAYING banner; when the game closes, a Windows toast reports the session time and total playtime. It also creates a readable playtime.txt log, with sessions grouped by date. Data is kept locally in JSON, and interim session details are saved every 60 seconds so an incomplete session can be finalized on the next startup. The dashboard retains up to 100 sessions. Detection depends on the game executable being named Endfield.exe. The tracker requires Windows and Node.js, uses built-in Node.js modules without external dependencies, and setup uses batch files, with a VBScript launcher option. Users can set an initialOffset to account for playtime before installation; the default is zero. The local dashboard is not accessible from other machines. The tracker is free to use and modify.

GameDiary tracks PlayStation Portable game playtime in the background and presents statistics for individual games and the full library. Its PSP release has a kernel-mode tracking plugin and a user-mode application. Tracking covers native PSP games and PlayStation 1 classics running through POPS; statistics include session history and activity graphs. The plugin also extracts icons from EBOOTs and ISOs. The interface supports English, Spanish, Portuguese, Russian, German, French, Italian, Japanese, and Chinese, with language detection from PSP settings. Web tools let users edit sessions visually and merge backup files from multiple Memory Sticks or PSP consoles. The responsive web interface works from a PC or smartphone with a backup.json file exported by the PSP app. Installation requires a PSP 1000, 2000, 3000, or Go with custom firmware and a Memory Stick or MicroSD-to-MS adapter. The project is free under the MIT License. Some homebrew that overwrites RAM boundaries or uses custom interrupts may temporarily pause tracking intervals.
