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 a couple of 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.
From idea to the App Store
Whether it’s a focused utility like the apps above or a companion app for an existing business, we handle the full lifecycle: UI/UX design, native Swift development, on-device sensor and hardware integration, App Store submission, and ongoing updates.
