What is Fonoster?
Fonoster ships four releases in a day to make linking a Twilio number a single step.
Fonoster went from v0.35 to v0.38.1 on October 28. The thread is Twilio: trunk provisioning for a number link is now idempotent, a Twilio number can be linked to an app or SIP agent in one API call, linking moved server-side with an API key or Auth Token (a breaking change), and the Numbers page can do it from the UI. v0.35 also lets Routr be configured through routr-one.yaml.
What is Superhuman?
Superhuman adapts to iPhone Duo and iOS 27 as its mobile app catches up.
Superhuman is a premium email client that is building out a calendar and team features around its mail core. Its October mobile batch added Compact Mode, swipe actions and attachment-aware AI. The newest release optimizes the iOS app for the dual-screen iPhone Duo and for iOS 27 screen sizes.

Fonoster
6.3COMMS
Fonoster ships four releases in a day to make linking a Twilio number a single step.
◆ Current state
Fonoster went from v0.35 to v0.38.1 on October 28. The thread is Twilio: trunk provisioning for a number link is now idempotent, a Twilio number can be linked to an app or SIP agent in one API call, linking moved server-side with an API key or Auth Token (a breaking change), and the Numbers page can do it from the UI. v0.35 also lets Routr be configured through routr-one.yaml.
◆ Where it's heading
After rebuilding its SIP and media edge and defaulting to HTTPS in the 0.31 to 0.33 run, Fonoster is now working on onboarding, using Twilio as the way to bring an existing number. The release rate stays very high and breaking changes still land in minor versions.
◆ Prediction
Expect the same number-linking flow for other carriers, or more Numbers page work; the entries only cover Twilio so far.
Superhuman
5.0COMMS
Superhuman adapts to iPhone Duo and iOS 27 as its mobile app catches up.
◆ Current state
Superhuman is a premium email client that is building out a calendar and team features around its mail core. Its October mobile batch added Compact Mode, swipe actions and attachment-aware AI. The newest release optimizes the iOS app for the dual-screen iPhone Duo and for iOS 27 screen sizes.
◆ Where it's heading
Superhuman is closing gaps on mobile and in the calendar: density, gestures, recurring meetings, week settings and room booking. The Duo note points to multi-pane mobile layouts next, with mail and calendar side by side, which would tie the two halves of the product together on the phone.
◆ Prediction
Expect a dual-pane Duo layout that shows an email next to the calendar, as the release itself promises, plus more calendar basics.
