Unit Converter For Engineers vs PLC IO Checkout

Built for engineers who work with units most converters don’t have. No ads. No popups. No distractions. If you’ve ever opened PDFs, charts, or old handbooks to convert Rockwell hardness, wire gauge, HVAC airflow, radiation dose, water hardness, or torque units — this app replaces all of that. Units you usually can’t find in converter apps Material Hardness Rockwell (HRC, HRB, HRA), Vickers, Brinell, Knoop, Mohs, Shore Wire Gauge AWG, SWG, MCM, kcmil, diameter, cross-sectional area HVAC & Airflow CFM, ACH, BTU/h, tons of cooling, kW, airflow per area and per person Water Quality & Chemistry ppm, mg/L as CaCO₃, grains per gallon (US/UK), °dH, °fH, dKH, mmol/L, meq/L Radiation & Radioactivity Becquerel, Curie, Gray, rad Mechanical & Structural Torque, stress, density, pressure, moment of inertia (kg·m² ↔ slug·ft²) Built for real work environments • Works 100% offline in labs, plants, and job sites • Fast search and instant conversion • Scientific notation for precision work • Fraction input mode for field and construction use • Clean, engineer-friendly interface — no ads, ever This app replaces reference charts, calculators, handbooks, and repeated Google searches with one reliable tool in your pocket.

IO Checkout replaces the printed spreadsheet and highlighter you carry into a panel. Import your I/O list, verify every point, track the punch list, and hand your client a professional PDF report before you leave site. Built for solo integrators, controls engineers, commissioning technicians and small OEM machine builders who need the paperwork done properly without dragging a laptop into the field. Everything works offline. There is no account, no server and no sign-in. IMPORT YOUR I/O LIST Export a CSV from Excel and bring it straight in. A mapping screen lets you match your spreadsheet's columns to tag, description, I/O type, address, terminal, signal detail and engineering range, with a live preview before anything is created. Real I/O lists are messy, so the importer expects it: quoted fields with embedded commas, Windows line endings, stray encodings, blank rows and duplicate tags are all handled without losing data or crashing. You can also start an empty project and add points by hand. CHECK POINTS THE WAY YOU ACTUALLY WORK Mark each point Pass, Fail, Punch List or N/A. Every change is stamped with the time and your initials automatically, so the record builds itself while you work. Filter by status or I/O type, search by tag or description, and see progress broken down between passed, failed and punch at a glance. Rows are built for gloves and sunlight: large targets, high contrast, full dark mode support. RAPID MODE One point at a time, full screen. Swipe right to pass, left to fail, or use the oversized buttons — then it advances straight to the next unchecked point. This is the mode for walking a panel with a meter in your other hand. Undo is always one tap away. PHOTO EVIDENCE Attach photos of terminations, nameplates or wiring faults directly to a point, from the camera or your library. They stay with the record and print in the report appendix. PUNCH LIST THAT KEEPS ITS HISTORY Failed and flagged points collect into a dedicated punch list. When an item is fixed, resolve it with a note — the original failure, its date and its photos are all preserved. Your report shows both the problem and the fix, which is exactly what a client wants to see. CLIENT-READY PDF REPORT Generate a multi-page report carrying your own company logo: • Cover sheet with client, site, machine, inspector and summary statistics • Full point-by-point table with status, timestamps, initials and notes • Punch list section with resolutions • Photo appendix • Signature block with your captured signature and a client witness line Share it by AirDrop, Mail or Files. Results also export to CSV for clients who want the data back in Excel. PRIVATE BY DESIGN Every project stays on your device. No account, no cloud, no analytics, no tracking, nothing transmitted anywhere. It works the same in a steel enclosure with no signal as it does at your desk. TRY IT FIRST New installs get a 5-day free trial with every feature unlocked. After that, a single 29.99 USD purchase unlocks the app permanently — no subscription and nothing that renews. Projects you have already created remain on your device and fully editable whether or not you unlock. Not sure where to start? The app can generate a realistic 40-point sample project so you can walk the entire workflow, report included, without importing anything.
