EasyArduinoBleTerm vs MetalScope

Using Arduino's BLE, we can create a terminal and plotter similar to the Arduino IDE. The plotter's width can also be changed over time with your finger. Operation has been confirmed with the ESP32_BleSerial library.

MetalScope turns your iPhone into a professional GPU benchmarking lab. Run real Metal shader workloads and see exactly how your device stacks up against the entire Apple silicon lineup. COMPREHENSIVE BENCHMARKS Three precision tests built on Apple Metal API — compute throughput, render pipeline performance, and memory bandwidth. Each test runs multiple iterations to deliver stable, repeatable scores. INSTANT DEVICE SCORING Get a unified performance score the moment a benchmark completes. Sub-scores break down compute, rendering, and bandwidth so you understand exactly where your GPU excels. DEVICE RANKING Compare your iPhone against a built-in database of every Apple chip — from A11 to A18 Pro. See percentile placement and discover how your device compares across all dimensions. BENCHMARK HISTORY Track performance over time. Every run is saved locally with full details — scores, date, iOS version, thermal state. Spot trends and detect degradation. GPU INFORMATION Explore your Metal GPU capabilities: family, feature sets, core count, supported texture formats, and more. Know your hardware inside out. DESIGNED FOR ACCURACY - Low-battery warning prevents throttled results - Background app guidance for clean measurements - Multiple iterations reduce variance - Dark interface minimizes thermal impact during tests All data stored locally with SwiftData. No account required. No data leaves your device.
