TCG Archivist is the ultimate collection management tool for Magic: The Gathering players. We believe sorting your collection is the wrong approach. Sorting is time consuming, impossible to maintain, and never actually gives you a clear picture of what you own. TCG Archivist is built around a better system. One that the world's most efficient warehouses and retailers have used for decades. Scan your cards into labeled storage locations. No sorting required. When you need a card search the app, find the location, and have it in your hand in under a minute. Your entire collection becomes fully searchable, filterable, and always up to date. Know exactly what you own. Track your collection value in real time. Build decks from cards you actually have. Find any card in seconds. For players with larger collections the CSC100 hardware scanner makes building your digital catalog dramatically faster, but any camera will get you started today. Your collection. Always searchable. Always in reach. Terms of Use : https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

I built UnitForge because every unit converter I tried was either full of ads, locked basic units behind a paywall, or just got the math wrong. UnitForge is different. Pay once, use forever. No ads. No subscriptions. No tracking. No accounts. It just works. What you get: - 40+ conversion categories — from everyday (distance, weight, temperature) to engineering (viscosity, thermal conductivity, torque) to medical (blood glucose, HbA1c, cholesterol) - Cooking conversions that actually work — 1 cup of flour ≠ 1 cup of sugar. Select your ingredient, get the right weight. 25+ ingredients with USDA-sourced density data. - Wrench & socket size finder — enter a metric size, get the closest SAE match above and below (and vice versa). No more guessing in the garage. - Mixed unit display — see results as "5 ft 10 in" instead of "70 inches" or "3 lb 6 oz" instead of "54 oz" - Decimal precision control — set 0 to 10 decimal places in Settings - Dark mode — full support with auto/light/dark toggle - Zero data collection — we don't use analytics, don't make network requests, and have no idea how you use the app - Works offline — every conversion is computed on-device All conversion ratios are sourced from NIST, BIPM, and USDA, with 770+ automated tests ensuring accuracy.
