Centering50: TCG & Sports Card Grading Tool Stop guessing and start grading with confidence. Whether you are a hardcore Pokémon TCG investor, a sports card flipper, or a casual collector, centering is the #1 reason cards fail to hit a Gem Mint 10. Centering50 is the professional-grade scanner designed to help you predict your grade before you spend a cent on submission fees. WHY CENTERING MATTERS In the modern hobby, the price gap between a PSA 9 and a PSA 10 can be thousands of dollars. Professional graders at PSA, BGS, SGC, CGC, and TAG use digital precision to measure border ratios. If your card is even 2% off, you lose the Gem Mint dream. Centering50 brings that same laboratory precision to your smartphone. PRECISION FEATURES FOR COLLECTORS: "Smart-Snap AI: Our algorithm helps you detect card borders for lightning-fast scanning of modern Pokémon, Magic: The Gathering (MTG), Lorcana, and One Piece cards. Save time with AI-assisted alignment, then fine-tune for 0.1% precision." Auto-Straighten Technology: Don't worry about perfect alignment. Scan at any angle and the app will instantly fix the tilt. The "Magenta Line" Manual Mode: For vintage cards or thick-bordered sports cards (Topps, Panini, Upper Deck), use our high-contrast measurement guides to set your own anchor points with 0.1% accuracy. Grading Standard Library: Instantly compare your results against the official 2026 standards: PSA: 55/45 Front (New 2025 Standard) BGS: 50/50 for Black Label eligibility SGC & CGC: Real-time centering thresholds Front & Back Analysis: Don't get rejected for a 90/10 back! Measure both sides independently to ensure your submission is truly "Perfect." 15x Precision Zoom: Perfectly align your guides on thin silver or gold borders with our enhanced magnification tool. SAVE MONEY ON SUBMISSION FEES Sending cards to be graded is expensive. Why pay for a "Near Mint 7" when you could have known the result at home? Use Centering50 to filter your collection and only send your strongest candidates. It’s the ultimate pre-grading utility for: Pokémon TCG (English & Japanese) Sports Cards (Basketball, Baseball, Football, Soccer) Disney Lorcana & One Piece TCG Yu-Gi-Oh! & Magic: The Gathering DESIGNED FOR THE 2026 HOBBYIST We know you’re scanning in different lighting. Our app features Dynamic Contrast Adjustment and Skew Correction, so even if your photo is slightly tilted, our math remains perfect. HOW TO USE: Place your card on a high-contrast, flat surface (no sleeves for best results). Take a photo directly from above. (with the green bubble in center) Align the Centering50 guides with the card edges and the internal art border. (Optionally: Unlock the image and move/resize/rotate) Get your LR (Left/Right) and TB (Top/Bottom) ratios instantly.

FR Queue Optimizer

FR Queue Optimizer is your mobile planning companion for Walmart queue drops. It calculates exactly when to start your bot and when to change your refresh delay so your automation hits queue live on the dot—typically 8:00 PM Wednesday. Whether you run a desktop bot or automation on another device, this app handles the timing math and sends native alerts to your phone so you never miss a start or drop window. WHAT IT DOES Your automation refreshes a product page on a loop using a delay in milliseconds. FR Queue Optimizer gives you exactly two numbers: • Start delay — set this when you begin your task • Drop delay — switch to this at the exact clock time shown The app schedules everything around your timezone and tells you precisely when each step happens, so your final refresh lands exactly at queue live. KEY FEATURES PRESET PLANS Ready-made schedules for common final delays (5,000 ms down to 1,000 ms). Each card shows when to start, what delay to use, and the exact drop time. Includes Late Drop presets if you want to start closer to go-live. CUSTOM OPTIMIZER Enter your own start time, delays, and queue-live time. Supports Central, Eastern, and Pacific timezones. INSTANT & DEFERRED SWITCH MODES Some bots apply a new delay immediately; others finish one more slow refresh first. Toggle between Instant Switch and Deferred Switch so your drop reminder matches how your bot actually behaves. LIVE DEMO Run a short simulation on any preset to verify the timing before a real drop. NATIVE PHONE ALERTS Activate a plan and get reminders on your iPhone: • 10 minutes before start • 10 minutes before drop • At start, drop, and queue-live time Alerts work in the background—enable notifications when prompted and use Test Alert to confirm they’re working. WORKS OFFLINE All scheduling runs on your phone. No account required. No server needed. BUILT FOR TEAMS Share the same start times and drop windows with your group so everyone hits queue live together. IMPORTANT This app is a timing planner and alert tool. It does not run automation or purchase products for you. Your bot or automation software still runs on your PC or other device—you use FR Queue Optimizer to know exactly when to start and when to change delays. Perfect for resellers and collectors who want reliable queue timing without guessing clock math on drop night.
