IDFA Viewer vs TokenCounter

IDFA Viewer is the simplest way to find and copy your device’s Identifier for Advertisers (IDFA). Whether you’re a developer, marketer, or just curious about your device’s data, this app gives you fast and reliable access to your IDFA. Key Features: • Instantly view your iPhone’s IDFA • Copy the IDFA with a single tap • Clean and minimal design, no distractions Why IDFA Viewer? Apple’s Identifier for Advertisers (IDFA) is a unique identifier used in apps for analytics and advertising. Finding it manually can be confusing — IDFA Viewer makes it quick and effortless. Perfect for developers testing ad frameworks, marketers validating campaigns, or users who want transparency about their own device identifiers.

TokenCounter is the simplest way to keep tabs on what your Anthropic API account is costing this month — without giving up your privacy. Paste your Admin API key once, and the app fetches live cost data straight from Anthropic to your iPhone. You'll see: • Month-to-date spend across your whole organization • Today's intra-day cost estimate (Anthropic's daily report only closes yesterday's bucket; we add a token-priced estimate of today) • Breakdown by model • Quick visual sense of whether you're under, on track, or over your usual monthly burn • A monthly spend limit you set on-device, with a gauge that warns as you approach it • An optional alert the first time you cross 90% of your limit in a month TokenCounter does not have a server. The app talks directly from your iPhone to api.anthropic.com using your key. Nothing about your account, key, usage, or cost ever passes through any third party — including us. WHY YOU'LL LIKE IT • No account to create. • No analytics, no crash reporting, no advertising SDKs, no third-party trackers. Zero. • Your Admin API key is stored only in the iOS Keychain on this device, protected by Face ID / Touch ID / your passcode. • One-tap "Disconnect" in Settings wipes the key from Keychain. • Native SwiftUI, no web views for data, no bloated frameworks. WHAT YOU NEED TokenCounter reads from Anthropic's Admin API, which requires: 1. An organizational Anthropic account (admin keys aren't available on individual accounts). 2. An Admin API key. The onboarding flow walks you through creating both. If you already have them, it's about 30 seconds to be up and running. WHO IT'S FOR Developers, founders, and ML engineers who use Anthropic's API every day and want a fast way to check spend without logging into the Console on the web. Especially useful if you're testing prompts that could rack up cost quickly and you want a glanceable number on your home screen.
