Arknights: Endfield Playtime Tracker vs RoTracker

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.

RoTracker is a web service for monitoring Roblox activity. It shows games played, time spent, and activity patterns in daily, weekly, and yearly views. A game library records play history and session counts, while live updates show what is being played now. Streak tracking covers current and longest streaks. Multiple Roblox accounts can be linked to one dashboard, after ownership verification enables automatic tracking. RoTracker says it collects activity through Roblox public APIs and does not access private or non-public Roblox data. It requires neither a Roblox password nor a browser extension or account access. Linked activity may appear on public leaderboards, with a Hide from leaderboards option for anonymous display. The service is in public beta and currently free: the Free plan is free, with no credit card or hidden fees. Data export is basic. The privacy policy lists encryption in transit, password hashing, access controls, security assessments, and suspicious-activity monitoring.
