iOS App Development
Native iPhone apps, designed and built end-to-end — from concept to a published App Store listing.
Focused, well-built tools — not bloated apps
C&S Industries designs and develops native iOS apps using Swift and Apple’s current frameworks. We favor the same philosophy on mobile that we bring to engineering work: solve the actual problem, skip the clutter, and ship something reliable. Below are some of the apps we’ve built and published on the App Store.
MyRPMCalc
Acoustic engine tachometer
Point your phone at a running engine and read its RPM instantly, straight from the sound of the exhaust — no OBD adapter, no clip-on sensor, no wiring. Works on cars, motorcycles, mowers, generators, chainsaws, and other small engines, with a hands-free Auto-Freeze mode for working solo.
LevelUP Tool
Ten jobsite tools in one app
A bubble level, spirit level, angle finder, plumb bob, miter cut calculator, feet-inch-fraction calculator, stair calculator, board foot calculator, 3-4-5 square-up, and room measure — all powered by your iPhone’s motion sensors, built for DIYers, contractors, and woodworkers.
Mil-Dot Ranger
Reticle-based range estimation
Turn a mil-dot or MOA reticle reading into an instant distance estimate. Pick from 30+ North American game animals, steel plates, and competition targets, overlay a silhouette on your scope view, and let the built-in inclinometer correct for uphill and downhill shots — all offline.
MOACalc for Shooters
Shot group analyzer
Photograph your target, mark your shots, and get group size in MOA, offsets from your aiming point, and the exact windage and elevation clicks to zero in. Includes firearm and ammo profiles, automatic weather conditions, and annotated session history.
GhostAlias
Instant code-name generator
One tap generates a sharp two-word code name for your next project, drawn from thousands of combinations, with a cinematic decrypting reveal and a synthesized sci-fi voice. Fully offline, with no accounts or data collection.
StarGazer Terrestrial
Live sky map for your iPhone
Hold your phone up and see the stars, all 88 constellations, planets, the Moon and satellites like the ISS right where they really are. Search for anything and get plain-English directions to find it, or point down to see the sky through the Earth. Works offline.
