Install DatePrism

DatePrism is free, with no ads and no trackers. Choose your platform below.

Current version: 1.0.2.

Installation warning: since DatePrism isn't (yet) distributed via the Google Play Store or the Microsoft Store, Android and Windows will show security prompts during installation — this is expected for any app installed outside an app store, not a sign of a problem with the file.

Android: Google Play Protect shows "App blocked to protect your device". Tap More details, then Install anyway. An antivirus app (Bitdefender, etc.) may also flag the file out of caution — check its authenticity against the SHA-256 fingerprint below before dismissing the warning. You can also check this file yourself by uploading it to VirusTotal (free, no sign-up).
Windows: SmartScreen may show "Windows protected your PC". Click More info, then Run anyway. The signature fingerprint below lets you verify the file's origin.
