Quick UUID Generator vs TKN

Sometimes you just need one identifier, right now, on the phone in your hand. Not a code snippet, not a terminal, not a website you have to trust with it. Open the app and the identifier is already there. Tap it and it is on your clipboard. WHICH VERSION YOU GET, AND WHEN IT MATTERS Quick UUID generates four kinds, and the difference is worth knowing before you paste one into a database. • v4 is pure randomness. The default, and the right choice when you need something unique and have no reason to care about order. • v7 carries the time it was made in its leading bits, so v7 identifiers sort in the order they were created. That is what makes it pleasant as a database primary key: new rows land next to each other instead of scattering across the index. • v1 also encodes a timestamp, alongside a random node value: nothing about the device is embedded in it. Older systems expect this one. • v5 is the odd one out, because it is not random at all. You give it a name and a namespace, and the same name always produces the same identifier. Generate it today or next year, on this phone or another one, and the value is identical. The namespace is chosen with the built-in DNS, URL, OID and X.500 selector. UPPERCASE OR LOWERCASE One tap switches the output between cases. Some systems insist on uppercase, others on lowercase, and retyping a 36-character string by hand is how mistakes happen. EVERYTHING YOU GENERATED IS STILL THERE The full history stays on the device, with the version and the time next to every value. Tap any entry to copy it again. Useful when you generated three identifiers in a row and now need the second one back. WORKS WITH NO NETWORK Everything happens on the phone. No account, no sign-in, no registration: the identifiers are created on the device and never leave it, so the app keeps working on a plane, inside a locked-down office network, or in airplane mode.

TKN is a financial firewall for AI API spending — a developer's spend dashboard and key vault for OpenAI, Anthropic, xAI (Grok), and Google Gemini, in one OLED-black terminal on your phone. THE PROBLEM A leaked key or a runaway loop can quietly burn hundreds of dollars before your monthly invoice ever arrives. TKN puts your AI spend somewhere you'll actually see it. ONE DASHBOARD, EVERY PROVIDER Connect your provider billing keys and see today's spend across all of them at a glance, with a per-provider breakdown — no more logging into four separate billing consoles. • OpenAI & Anthropic — organization/admin key • xAI (Grok) — management key • Google Gemini — Google Cloud Billing Spend figures come straight from each provider's official billing API, which reports on a daily cadence. YOUR KEYS NEVER LEAVE YOUR DEVICE API keys are stored in the iOS Keychain — encrypted, never in plain text, and locked behind Face ID. TKN does not upload your provider keys to any server. A KILL SWITCH WHEN YOU NEED IT Something looks wrong? The kill switch is a deliberate, swipe-to-confirm control — designed so you can never trigger it by accident. SPEND RULES Define what "normal" spend looks like and keep an eye on it from the Console. START WITHOUT AN ACCOUNT The whole app runs in a demo mode with no sign-up. Create an optional account — Sign in with Apple, Google, or GitHub — only when you want to sync your setup across devices. You can delete your account and its data from inside the app at any time. TKN PRO Free covers the dashboard for a single provider. Pro unlocks unlimited providers, spend rules, and the kill switch — as a monthly or annual subscription, or a one-time lifetime unlock. Subscriptions auto-renew unless cancelled; manage them anytime in your Apple ID settings. Built by developers, for developers. TKN Pro is available as an auto-renewing subscription (monthly or annual) or a one-time Lifetime purchase. Payment is charged to your Apple ID at confirmation. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the period; manage or cancel anytime in your Apple ID settings.
