Mobile Applications

The PromethistAI Mobile Clients are available on the Apple App Store and Google Play Store under the name PromethistAI. These applications are the main way end-users access and interact with Relational Agents built on the PromethistAI Platform.

They are designed to be intuitive, support modern devices, and provide feature-rich experiences such as QR enrollment, agent sharing, and multimodal interactions.

Processing Region (US/EU)

The mobile app selects a processing region (US or EU) for agent sessions.

  • Default: Auto-detected on first launch based on network and location signals

  • Override: Change anytime under Settings → Region (per device)

  • Why it matters: Choose the closest region for lower latency and to meet data-residency needs

Supported Devices Matrix

PromethistAI classifies supported devices into three categories to clarify performance expectations and feature availability.

Category iOS Android Implications

Fully Supported

  • iPhone (12+)

  • iPad Pro (2021+)

  • iPad Air (2022+)

  • iPad Mini (2021+)

  • iPad (9th gen+)

  • Macs with Apple Silicon (M1+)

  • Google Pixel 7 or newer

  • Samsung Galaxy S22 or newer

  • Samsung Z Fold5 or newer

  • Samsung Z Flip4 or newer

  • OnePlus 12 or newer

  • OnePlus Nord 4 or newer

  • Xiaomi 12 or newer

  • Motorola Edge 60 Pro or newer

  • Motorola Razr 50 Ultra or newer

Full experience enabled:

  • Smooth rendering, HDR graphics

  • Low-latency audio

  • Android: speech-to-speech with barge-in

Best Effort (Performance Tier)

  • iPhone 11–12

  • iPad Pro (2018–2020)

  • iPad Air (2020)

  • iPad Mini (2019)

  • iPad (7th–8th gen)

Other Android devices meeting mid-range criteria:

  • 4–7 GB RAM

  • Android 10–12

  • Released 2020–2021

(e.g., Pixel 4a/5/5a; Galaxy A52–A54; Oppo Reno 6–8; Xiaomi Mi 10/11; older mid-range and flagships)

Core features work with reduced performance:

  • Graphics downscaled

  • Slower transitions

  • Android: automatic fallback to Push-to-Talk

Unsupported / Disqualified

  • iPhone X and older

  • iPhone SE (all gens)

  • iPhone 8 and earlier

  • iPad Pro (pre-2018)

  • iPad Air (pre-2020)

  • iPad Mini (pre-2019)

  • iPad (6th gen and older)

  • Intel Macs (all models, pre-2020)

Devices failing baseline:

  • < 4 GB RAM

  • Android 9 or lower

  • Released 2019 or earlier

  • Android Go devices

  • Huawei (no Play Store)

  • Low-end OEMs

Installation may be possible, but not supported:

  • Instability likely

  • Features may fail

  • Android: speech features unreliable or unavailable

Agent Detail

Iphone width=300

Each agent opens to a detail view containing:

  • A configurable header image and agent name

  • Concise description of purpose and information about the agent

  • Button to start a new session

  • If the agent uses Anonymous Mode, a toggle labeled Anonymously appears under the Talk button. This toggle applies only to the upcoming conversation and returns to off when the conversation ends

All this detail content is configured in the PromethistAI Platform by the agent creator.

During sessions:

  • The 3D presence runs locally

  • Voice interaction streams in real time

  • Chat interface is available anytime

  • Multimodal steps (forms, confirmations, image tiles, embedded webpages) display inline

  • When the conversation naturally ends, the app automatically shows a close-session prompt—no manual action needed

Sharing

Agents can be shared via QR code or direct link.

Recipients without the app are redirected to the store page and, after installation, taken directly to the shared agent.

Cross-Region QR Scanning

You can scan a QR code (or open a link) for an agent hosted in a different region than your current app region—for example, an EU agent on a US-configured device.

  • The app shows a non-blocking warning and then launches the session without interruption

  • You may experience higher latency or reduced performance if you proceed without switching

  • You can switch any time under Settings → Region; organization policy may enforce a specific region

  • This behavior does not move or modify your data; it only affects session routing on mobile

Connectivity & Performance

  • The voice pipeline requires stable internet for low-latency turn-taking

  • 3D rendering is local to keep visuals fluid on congested networks

On Android:

  • Fully supported devices → continuous speech-to-speech with barge-in

  • Lower-tier devices → automatic fallback to Push-to-talk for reliability

On iOS:

  • No fallback needed due to Apple hardware/audio uniformity
