Read full descriptionHide full description
The simplest way to experience the worldβs 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 β’ Native iOS Experience β Clean dark interface, smooth gestures, and responsive haptics built for your thumb. β’ Swipeable Comparison β Effortlessly swipe through answers from GPT, Claude, Gemini, Grok, and DeepSeek. β’ Voice Dictation β Speak your ideas hands-free on the go. β’ Multimodal Attachments β Seamlessly attach photos, documents, and screenshots for instant analysis. β’ Thread History β Keep every multi-model conversation organized, searchable, and saved. THE FRONTIER MODELS INCLUDED: β’ OpenAI: GPT 6.1 Sol, GPT 6 Luna β’ Anthropic: Claude Opus 5.5 & Claude Sonnet 5.5 β’ Google: Gemini 3.1 Pro & Flash 3.8 β’ xAI: Grok 4.7 β’ 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.

at8pm is your honest journal. Every entry you write today locks at a time you choose β 8pm by default. Once it locks, that's it: no editing, no rewriting history, no quietly polishing what you actually felt in the moment. Just an honest record of your day, exactly as you wrote it. WRITE HOWEVER FITS THE MOMENT Type it out with rich text: bold, italic, underline, strikethrough. Or just talk β record a voice note right inside an entry and see it as a waveform, or capture a Squope, a quick square video note. No typing required. Add a photo or a location if the moment needs it. A HABIT THAT STICKS Keep your streak going day by day. A quick glance at your lock ring shows how much time is left before today closes β and a tap shows your current streak alongside it. MADE TO BE SHARED, SOMETIMES Turn any entry into a beautifully designed card β pick from several styles β and share it straight to Instagram Stories or anywhere else. Your private thoughts stay private until you decide otherwise. GENUINELY PRIVATE Entries sync across your devices with your own private iCloud account β never a third-party server. Lock the whole app behind Face ID for an extra layer of privacy. AT8PM PRO at8pm is free to download and use for up to 2 entries per day.
