Sendcove (formerly Postr) vs Zernio
Last updated 15 October 2026
Sendcove is the social scheduler formerly called Postr. Its official App Store release notes confirm the rename, and the listing names Minner Labs LLC as the developer and seller. The current website, support route and terms describe the service to evaluate; account permissions, trial conversion and cancellation behavior still need account-specific checks.
