The simplest way to experience the world’s best AI models on iPhone. Why choose between ChatGPT, Claude, and Gemini when you can have all of them in one place? Sphere is designed from the ground up for iOS, giving you an effortless, iPhone-first experience with zero technical friction. NO SETUP. NO API KEYS. JUST PURE SIMPLICITY. Most multi-model tools feel like complicated developer playgrounds. Sphere is different. There are no API keys to configure, no confusing parameters, and no cluttered web views. Just open the app, type or speak your prompt once, and watch top frontier models generate answers side-by-side in real time. DESIGNED EXCLUSIVELY FOR IPHONE • Native iOS Experience — Clean dark interface, smooth gestures, and responsive haptics built for your thumb. • Swipeable Comparison — Effortlessly swipe through answers from GPT, Claude, Gemini, Grok, and DeepSeek. • Voice Dictation — Speak your ideas hands-free on the go. • Multimodal Attachments — Seamlessly attach photos, documents, and screenshots for instant analysis. • Thread History — Keep every multi-model conversation organized, searchable, and saved. THE FRONTIER MODELS INCLUDED: • OpenAI: GPT 6.1 Sol, GPT 6 Luna • Anthropic: Claude Opus 5.5 & Claude Sonnet 5.5 • Google: Gemini 3.1 Pro & Flash 3.8 • xAI: Grok 4.7 • DeepSeek: R1 Reasoning FREQUENTLY ASKED QUESTIONS Why use Sphere instead of a single AI app? Every model has unique superpowers. GPT excels at logical reasoning and structured formatting. Claude produces nuanced, natural writing. Gemini has unparalleled live web awareness. DeepSeek provides deep mathematical step-by-step thinking. Sphere lets you cross-check and pick the best answer every single time. Do I need my own API keys? No. Sphere handles all model access under one simple subscription. You never have to create developer accounts or manage API credits. How does the subscription work? Sphere requires an active Sphere Pro subscription (available monthly or annually at a 43% discount). Your subscription gives you full access to all frontier models, parallel multi-model streaming, and file attachments with no token calculations or surprise bills. SPHERE PRO Upgrade to Sphere Pro for complete access to frontier models, side-by-side multi-model streaming, and advanced document analysis. Subscriptions are billed securely through your Apple ID and can be managed or canceled anytime in your iPhone Settings → Apple ID → Subscriptions.
