Nous Research Opens a Beta of Hermes Mobile, Bringing Its Open Source Hermes Agent to iOS and Android
Hermes mobile app is now available for beta testing on both iOS and Android. TESTING TIME! 馃敟
Context
Users of a popular open source agent can now approve tools and manage bots and routines from a phone, connected to their own server instead of a chat app bridge.
Hermes Agent is Nous Research's open source agent, which runs on a local machine or a server with memory, tools and scheduled tasks, and until now was reached mainly through a terminal, desktop or messaging apps. The mobile beta surfaced around NousCon 2026, held in New York on Oct 30. The first post sharing the TestFlight link, by Sayo, drew more than 100,000 views.
Deep dive
Nous Research put up an official Hermes Mobile beta page on Oct 31 with separate sign up routes for iOS and Android. The iOS route is a TestFlight invitation for an app named Hermes Agent Mobile, listed with Nous Research as developer and version 1.0.0. The Android route goes through Firebase App Distribution and requires a Google sign in. TestingCatalog reported that the app is available for beta testing on both platforms, quoting a post by Sayo that first shared the TestFlight link.
The TestFlight listing describes the app as a way to connect to your own gateway, chat with the agent with streaming replies, approve tool calls and manage bots and routines from anywhere. The welcome screen offers either a Nous account or a connection to a self hosted server, which matches how Hermes Agent already runs: the agent lives on the user's machine or a cloud instance, and the phone is a client.
Access is limited. The official page asks visitors to reserve a spot, several users reported the Android tester limit filling up, and ByteForward notes the page does not document pairing, on device features or pricing. Nous Research has not announced a public store release date.
The launch follows Nous Research's Oct 27 change to paid plans that include one cloud agent with usage limits, and its NousCon event in New York on Oct 30.
What to expect next
Watch for a public App Store and Google Play release and for documentation of what the phone app can do on its own, such as voice, notifications or device sensors, versus what stays on the user's server. Another open question is pricing: whether the app stays free for self hosted users or ties into Nous Research's paid cloud agent plans. Feedback from the first testers will show how well tool approval works away from a desk.
