Fellow vs Threema: at a glance
What is Fellow?
Fellow's public changelog has been silent since 2021 — no recent direction is observable here.
The visible signal stops in spring 2021. The last few releases were calendar-extension touch-ups: action items appearing directly in the Google Calendar extension, public view-only meeting links for external attendees, and multi-calendar sync within a single Google or Office account. Nothing in this dataset reflects the past several years of Fellow's actual work.
What is Threema?
Threema ships a rare app change: spam reports for any chat on Android and iOS
On 13 November Threema improved spam reporting so users can flag single and group chats as spam on all mobile platforms, a change it credits to feedback from its in-app survey feed. It is the first app-level change in this window; the rest of the feed since July is security commentary, an August DDoS incident post and two Threema Work admin features.
Fellow vs Threema: editorial side-by-side
Fellow
0.0COMMS
Fellow's public changelog has been silent since 2021 — no recent direction is observable here.
◆ Current state
The visible signal stops in spring 2021. The last few releases were calendar-extension touch-ups: action items appearing directly in the Google Calendar extension, public view-only meeting links for external attendees, and multi-calendar sync within a single Google or Office account. Nothing in this dataset reflects the past several years of Fellow's actual work.
◆ Where it's heading
From the entries alone, no current trajectory can be inferred — the data is years stale. Whether Fellow has shifted to AI-meeting-notes or remained focused on the original meeting-management surface is not visible here and would be guesswork to assert.
◆ Prediction
Predictions can't be grounded in this data. The most useful next step is to refresh Fellow's changelog source so that present-day moves are captured.
Threema
5.0COMMS
Threema ships a rare app change: spam reports for any chat on Android and iOS
◆ Current state
On 13 November Threema improved spam reporting so users can flag single and group chats as spam on all mobile platforms, a change it credits to feedback from its in-app survey feed. It is the first app-level change in this window; the rest of the feed since July is security commentary, an August DDoS incident post and two Threema Work admin features.
◆ Where it's heading
Product news is starting to surface in the consumer app as well as in Threema Work administration, but at a slow pace and in small steps. The editorial line stays on security and resilience, with recent posts pitching Threema as the fallback channel during cyberattacks.
◆ Prediction
Expect further small, feedback-driven app changes alongside security commentary; the entries do not show when the larger items teased in July's roadmap post will ship.
