Sidekey turns your iPhone into a customizable wireless keyboard and shortcut pad for your own computer. Tap keys on your phone and they type on your Mac or Windows PC over your local Wi‑Fi — no extra hardware, no cables. Design the keyboard you actually want: add keys, build shortcuts (including combos like Cmd/Ctrl, and left/right modifiers), arrange them on a grid, and switch between layers and modes. Keep your most-used shortcuts one tap away. HOW IT WORKS Sidekey works together with a small, free desktop helper you run on the computer you want to control. Put both devices on the same Wi‑Fi, scan a QR code once to pair, and you're connected. Pairing is secured with a token, and your keystrokes travel directly to your own computer — never through us. FEATURES • Custom key designer — make your own keys, shortcuts, and layouts • Shortcuts & combos — Cmd/Ctrl/Alt/Shift, function keys, media keys, and left/right‑specific modifiers • Multiple layers & modes — flip between a full keyboard, a shortcut deck, a trackpad, and more • Trackpad mode — use your phone as a touchpad with left/right buttons • Voice typing — dictate with the system keyboard and send the text to your computer • Quick pairing — scan a QR code; reconnects automatically afterward • Works with Mac and Windows • Private by design — no account, no tracking, nothing sent to the developer REQUIRES THE FREE DESKTOP HELPER Sidekey needs the free Sidekey helper running on your Mac or Windows computer. Download it from the link on our support page. Questions or ideas? We'd love to hear from you.

ElectriCalc: The All-in-One On-Site Calculator for Electricians Are you still switching back and forth between multiple calculator apps and search engines every time you pull a wire? ElectriCalc brings together the essential everyday calculations that electricians encounter on the job site into one single app. It works completely offline—even in basements without internet or remote job sites with weak signals. ■ 10 Included Calculators - Voltage Drop Calculator: Enter wire length, current, and voltage to instantly find the voltage drop and percentage. - Wire Size Estimator: Estimate the appropriate AWG size based on current and Circular Mils. - Conduit Fill Calculator: Check the fill rate using wire and conduit diameters. - Box Fill Calculator: Verify if the junction box volume is sufficient. - Ohm's Law / Power Calculator: Intercalculate voltage, current, resistance, and power. - Motor FLA Estimator: Estimate Full Load Amperage using horsepower, voltage, and efficiency. - Transformer kVA Calculator: Calculate single-phase and three-phase transformer kVA and current. - Load Aggregator: Sum up the total connected load of multiple devices. - Conduit Bending (Offset) Calculator: Calculate bend distance and shrink values based on trigonometry. - Material Cost Estimator: Estimate wire costs using length, unit price, and quantity. ■ What Makes It Different? - Offline-First: Perform calculations anywhere on site without a data connection. - Favorites: Pin your most frequently used calculators to the top of the home screen. - Recent History: Your recent calculations are automatically saved so you can check them again instantly. - Trilingual Support: Seamlessly supports English, Spanish, and Korean, making it ready for Spanish-speaking crews on site. - No Login or Sign-up Required: Use it immediately upon installation with zero personal data collection. - Learn (Resource Center): Includes 8 easy-to-understand articles explaining the core concepts behind each calculation, such as voltage drop, AWG, single/three-phase, and motor inrush current. ■ Disclaimer This app performs calculations based on general engineering formulas and user-inputted values; it does not explicitly replicate the exact formula tables of a specific codebook. All calculation results are estimates for reference only. Final designs and construction compliance must be verified against the National Electrical Code (NEC) or local regulations, and confirmed by a licensed electrician. ElectriCalc was built for electricians who want to stop wasting time switching between multiple calculators on site.
