How Hosiqo compares and tests toolsFinal recommendation
Shortlist Carbon Voice when replacing status meetings and calls with async voice messages that get auto-transcribed and summarized matters most, and Echometer when tracking team health and morale trends across multiple sprints matters most. Run both through a week of actual calls to see which suits your workflow.

Psychology-based platform for agile retrospectives, recurring team health checks, and structured 1:1 meetings with AI-assisted suggestions.
Carbon Voice is an asynchronous voice-messaging and voice-notes app for iOS, Android, Web, and Apple Watch. Users record voice memos or messages with a single keystroke or swipe, and every message is automatically transcribed so it can be read, searched, labeled, and organized. The app is built around reducing real-time meetings and calls: instead of scheduling synchronous time, teammates exchange voice messages that the recipient can catch up on later. Layered on top is a large library of AI actions that turn raw voice into structured content — bulleted summaries, cleaned-up transcripts (removing filler words and fixing grammar), meeting notes, agendas, action items, professional emails, and longer documents such as PRDs and reports. Users can also query an AI assistant about any chat. A Global Voice feature can translate messages between languages, and messages can be sent to people who don't have the app via a secure email link. It is aimed at distributed teams, managers, and individuals who prefer talking over typing.

Echometer is a German-built platform purpose-made for running team retrospectives, recurring team health checks, and structured one-on-one (1:1) meetings. Aimed at engineering managers, scrum masters, and agile coaches, it pairs interactive retrospective boards with research-grounded survey questions so teams get guided, psychology-based reflection rather than a blank whiteboard. The retrospective tool offers a wide range of templates (such as Sailboat, Keep-Stop-Start, and others), supports both synchronous and asynchronous retros, and lets teams group, prioritize, and track measures coming out of each session. Health-check pulses run on a recurring basis to gather anonymous feedback and visualize how a team's agile maturity and satisfaction develop over time. A separate 1:1 meeting module provides templates and structured formats for manager-employee conversations. Echometer includes smart, AI-supported recommendations that surface food for thought and help brainstorm action items during retrospectives and 1:1s. The product is hosted in an ISO 27001-certified data center in Germany, offers a free tier, and is used by both small teams and large enterprises that want a consistent, data-informed approach to continuous team improvement. Pricing varies by plan. Check the official website for current pricing.
