I couldn’t verify a first release date for cryptohash.app from the available public results. The only directly related public page I found is a Trustpilot review page for the domain, which suggests the site was active by early 2026, but it does not confirm the app’s original release date.

What can be inferred

  • The domain was visible in public review listings by March 2026.
  • That means the web app existed by then, but the first release could have been earlier.
  • The search results also surfaced unrelated apps with similar names, so I would not treat those as evidence for cryptohash.app’s launch date.

Best-supported answer

At this point, the safest answer is: the first release date is not publicly confirmed from the available sources. If you need a precise launch date, it would require a reliable product announcement, archived homepage snapshot, or a developer statement tied specifically to cryptohash.app.

TL;DR: public evidence confirms activity by March 2026, but not the original release date.
