TrueSpeed vs 3D Printer Toolkit

TrueSpeed measures your real internet performance — download, upload, ping, jitter, and packet loss — in about 20 seconds, with no sign-in and no GPS access. WATCH IT LIVE See your test in progress from the Lock Screen and Dynamic Island with Live Activity — no need to keep the app open. EVERY METRIC THAT MATTERS • Download & upload speed (Mbps) • Ping (latency) and jitter • Packet loss • Your ISP name, IP address, and approximate location — from IP data, never your device's GPS TRACK IT OVER TIME The Insights tab logs every test locally on your device with a trend chart, so you can see whether your connection is actually getting worse — useful the next time you call your ISP. DIAGNOSE, DON'T JUST MEASURE The Tools tab adds a custom ping utility and a DNS benchmark, so you can tell whether a slowdown is your network or your DNS. BUILT-IN ACCURACY CHECKS TrueSpeed flags when a VPN may be skewing your results, so a low number doesn't send you chasing the wrong problem. SHARE YOUR RESULT Export a clean result card and share it anywhere in one tap. PRIVATE BY DESIGN No account, no login, no GPS access, no analytics SDK. Results are stored only on your device — never uploaded or sold. Clear your history anytime from Insights. Speed tests run against Cloudflare's public test network. TrueSpeed is free and supported by ads, which are hidden while a test is actively running.

3D Print Toolkit Design better-fitting 3D printed parts with powerful calculators built specifically for makers, hobbyists, engineers, and machine shops. 3D Print Toolkit helps eliminate guesswork when creating functional printed parts by providing tools for hole sizing, thread compensation, and thread reference calculations—all in one easy-to-use app. Whether you're printing bolt holes, threaded adapters, enclosures, or precision mechanical parts, these tools can help reduce trial-and-error and improve first-print success. Features Hole Compensation Calculator • Calculate the diameter adjustment needed for holes that print undersized. • Improve bolt, pin, shaft, and bearing fits. • Supports both inch and metric measurements. • Displays recommended compensation instantly. Thread Compensation Calculator • Adjust internal and external thread sizes for your specific 3D printer. • Fine-tune thread clearance based on real printed measurements. • Save calibration values for different printers, materials, and nozzle sizes. • Reduce repeated test prints and improve thread fit. Thread Reference Calculator • Quickly look up common thread dimensions. • Supports both Metric and Unified (UNC/UNF) thread standards. • Displays major diameter, pitch, tap drill size, and other useful machining references. • Great for designing printable threaded parts or preparing CAD models. Printer Profiles • Save calibration settings for multiple printers. • Store different offsets for PLA, PETG, ABS, TPU, and other materials. • Keep notes on successful print settings. Designed for Real-World Printing Perfect for: Functional parts Threaded adapters Replacement parts CNC and CAD projects Mechanical assemblies Workshop fabrication Engineering prototypes Privacy • No account required. • No subscriptions. • No internet connection required. • No ads. • All calculations and saved data remain on your device. Spend less time printing test parts and more time creating parts that fit the first time.
