Num Trainer vs Reimers App

Num Trainer is a lightweight app for building sharper number skills through four focused training games. Improve attention, memory, reaction speed, mental math, and logic with short practice sessions you can fit into your day. Choose your challenge: • Mental Math — solve addition, subtraction, multiplication, and division problems. • Memory Pairs — remember positions and match identical numbers. • Tap in Order — find and tap numbers from smallest to largest. • Digit-by-Digit Math — remember a number, then transform each digit using the same step. Adjust the difficulty to match your level, play at your own pace, and review completed sessions in Training History. With a clean, distraction-free interface and no ads or in-app purchases, Num Trainer keeps number practice simple and focused.

Reimers App is an educational tool designed for orthopedic surgeons, radiologists, and physiotherapists working with pediatric patients. The app provides fast, accurate measurement of two essential radiological indices for pediatric hip assessment: • Reimers Migration Index (RMI) — quantifies the degree of hip subluxation by comparing the extent of the femoral epiphysis outside the acetabulum. • Acetabular Index (AI) — evaluates the inclination of the acetabular roof as an indicator of acetabular development. How it works: 1. Import a pelvic X-ray directly from your camera or photo library. 2. Position 8 interactive anatomical landmarks (triradiate cartilage, acetabular edge, medial and lateral femoral head — bilaterally). 3. RMI and AI are calculated automatically for both hips. 4. Export the results as an image. Indicated for evaluation of developmental dysplasia of the hip (DDH), cerebral palsy, and other pediatric hip conditions. Available in Portuguese, English, and Spanish. Disclaimer: This app is intended for educational use.
