OS3 is a voice assistant built for Apple Watch. Talk to it like you would a friend, no tapping, no typing, just your voice. How it works: 1. Raise your wrist and start talking. OS3 listens, thinks, and responds out loud entirely hands-free. 2. Conversations feel natural with real-time voice powered by Google's Gemini AI. 3. Live captions appear on screen as you speak and as OS3 responds. Features: 1. Voice first interaction designed for the small screen, concise answers, no clutter. 2. Conversation history: revisit past conversations and pick up where you left off. 3. A visual orb that animates as OS3 listens and speaks. 4. iOS companion app for managing your account, viewing usage, and subscription details. 5. Sign in with Apple for quick, private authentication. OS3 requires an active internet connection on Apple Watch. An iPhone with the companion app installed is needed for account setup. Terms of Use: https://os3.app/terms/

Everything you do is scattered across apps, agents, wallets. Casberi is an inbox for your apps and a wallet of your own. It all comes together on your iPhone, iPad and Mac, with no sign-up, no servers and no tracking. A wallet of your own. Create your account in a tap and sign with Face ID. Send, receive and swap on Base, Ethereum and Robinhood Chain, and receive any token from another network, converted to the one you want. Only you hold the key: Casberi can never move your money. Swap in one sentence. "Swap $20 of USDC for ETH on Base." Fill in the blanks, see what you get, confirm with Face ID. Every swap is checked on the network first, so one that would fail or pay less than quoted is never signed. Swaps are powered by Relay. Buy gift cards with crypto. Pick a category and a merchant, and pay with USDC from your account. No card to add and no store account to make. Powered by Bitrefill. Safe by design. Add a recovery key so a lost phone never means lost money, add a second signer, and set a spend limit. Round up your transactions and save the change in any token. One wallet for all your money. Your wallets, exchanges, cards, savings and cash add up to one number. Follow any wallet address without a key or a signature; following only reads. See what you hold, what you spend and what's at risk. Every subscription, in one place. See the newsletters and lists filling your inbox beside the software and services you pay for. What each one costs, when it renews, and which you haven't used in a month. Follow the stocks behind your apps. Every app you use is made by a company. Markets shows its stock or token, with a heat map of your day and price alerts. Wallet, Work, Day, Life, Agents, Media, Social, Reading. More than 100 apps, sorted into the categories you live in. Apple's apps connect with one tap; other services with a read-only key, so Casberi can see but never change. One feed per category. Everything in a category lands in one feed, newest first: a deploy that failed, a payment that landed, a reply, a meeting coming up. Try it first. Casberi opens with a demo you can browse, wallet included. Clear it when you're ready and connect your own. Yours. No server, no sign-up, no ads. Sync through your own iCloud. Export everything to one file, or delete it all for good.
