Skye A | Symphony A | Hume AI A | GitHub Copilot B | |
|---|---|---|---|---|
| Tagline | An agentic iPhone home screen that replaces your static icon grid with AI widgets that proactively surface health, calendar, finance, and local context — without you having to open a single app. | OpenAI's open-source daemon that turns your Linear board into an always-on coding agent factory — tickets go in, pull requests come out. | Voice AI that reads + expresses emotion. | Microsoft/GitHub's autocomplete. Deep VS Code + JetBrains integration. |
| Category | Agents | Agents | Voice | Coding |
| Pricing | Waitlist / Beta (pricing not yet disclosed) | Free (open-source) | Free tier + pay-as-you-go | Free (limited) + $10/mo Pro + $19/mo Business |
| Best for | iPhone power users who are frustrated that Siri is still reactive and want their home screen to actually anticipate their day. | Engineering teams already using Linear + OpenAI Codex who want to stop babysitting agent sessions and instead let the issue tracker drive autonomous coding at scale. | Therapy apps, customer service, any voice agent where emotion matters. | Teams with GitHub already. Devs who don't want to change IDEs. |

| Kai's verdict | The concept is genuinely compelling — turning the home screen into a living AI layer is a smarter bet than yet another chat interface — but this is vaporware until it ships publicly and we see whether Apple's sandbox lets it breathe. (Verdict pending Phi's full review.) | Symphony is the most architecturally serious 'issue tracker as control plane' approach yet — 15K GitHub stars in weeks confirms the idea resonates — but it's still a rough, self-hosted engineering preview that demands Elixir chops and a Linear-only workflow. (Verdict pending Phi's full review.) | A-tier in its niche. The only one that actually gets emotion right. | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. |
