Hang it right the first time. Stud Finder turns your phone into a precise stud detector. Whether you're mounting a TV, hanging a heavy mirror, or building floating shelves, knowing exactly where the studs are means a clean, secure install — no patching mistakes, no wasted anchors, no second-guessing. HOW IT WORKS Stud Finder uses your iPhone's built-in magnetometer — the same sensor that powers the compass — to detect the metal screws and nails that fasten drywall to the studs behind it. Slowly slide your phone across the wall and watch the strength meter spike when you cross a stud. Same physics professionals rely on, now in your pocket. WHAT YOU GET • Real-time magnetic field detection • Visual strength meter with haptic and sound feedback • Calibration mode for accurate readings on any wall • Clean, distraction-free interface built for one-handed use • Works on drywall, plaster, and most interior surfaces • No ads, no clutter — just the tool you need WHY IT WORKS Modern construction uses metal fasteners every 16-24 inches to attach drywall to wood or metal studs. The magnetic signature these create is small but consistent — and your iPhone already has the sensor to read it. Stud Finder amplifies that signal and translates it into clear visual and tactile cues you can trust. FREE VS PREMIUM The free version lets you try basic detection. Premium unlocks full detection power, advanced sensitivity, and unlimited scans for serious DIY work and professional use. PERFECT FOR • DIY home renovation • Mounting TVs and heavy artwork • Installing shelves and cabinets • Childproofing furniture • Quick checks before drilling TIPS FOR BEST RESULTS • Remove your phone case for maximum sensitivity • Calibrate before each session for an accurate baseline • Move slowly and consistently across the wall • Cross-check by scanning both vertically and horizontally We built Stud Finder to be the simplest, most reliable wall scanner on the App Store. When you're standing on a ladder with a drill in your hand, you don't need a complicated app you need an answer.

About

SheetFlow

Read full description

SheetFlow is the modern, offline-first drywall and plasterboard material estimator designed for drywall contractors, home builders, DIY renovators, and construction estimators. Ditch the messy notebooks, buggy calculation sites, and outdated spreadsheet templates. Whether you are remodeling a home basement in the US or plastering a residential extension in the UK, SheetFlow calculates your drywall sheets, joint compound, fasteners, joint tape, and labor rates in seconds. LOCALIZED FOR US (IMPERIAL) AND UK (METRIC) SheetFlow dynamically localizes all terms and metrics to fit your local construction job standards. Instantly toggle between: - US Mode: Calculates in feet/inches, "Drywall" boards, standard sheet sizes (4x8, 4x10, 4x12), joint mud compound in gallons, coarse screws in pounds (lbs), and applies US Sales Tax. - UK Mode: Calculates in meters, "Plasterboard" sheets, metric board sizes (1.2m x 2.4m, 1.2m x 3.0m), joint compound tubs in kilograms (kg), screw boxes, and applies UK VAT rates. SMART MULTI-ROOM AGGREGATION Most calculator apps only allow you to estimate one room at a time. SheetFlow allows you to map out an entire residential project in a single quote: 1. Log individual rooms (e.g. Master Bedroom, Kitchen, Basement) with custom length, width, and ceiling height dimensions. 2. Toggle whether to include the ceiling area for each specific room. 3. Automatically deduct window and door cutouts to prevent material over-ordering. 4. Review the Master Materials report showing the total combined materials required for the entire building job. ITEMIZED LABOR & COST ESTIMATES Budget your building projects accurately by estimating labor services alongside material costs: - Toggle between flat project fees or per-sheet/per-board installation rates. - Customize local material unit pricing for boards, joint compound buckets, screws, and tape. - Review an itemized project billing invoice showing exact subtotals, tax (Sales Tax or VAT), labor services, and the final grand total. OFFLINE-FIRST HISTORY LOGGING Keep your contractor files organized on the go. SheetFlow stores all quotes locally on your device: - Review project statistics including total jobs, logged rooms, and cumulative estimated costs. - Quickly search, filter by region (US vs UK), and select previous quotes. - Load historical estimates back into the calculator to edit dimensions or update pricing rates. PRO PROFESSIONAL FEATURES SheetFlow offers a simulated sandbox to preview Pro-tier contractor utilities: - Limitless room additions: log as many rooms as your job site demands. - Export printable reports: print physical invoice sheets or save PDF quotes to share with clients via email or message. - Ad-free, private, and 100% offline-ready. Build smarter, order faster, and estimate accurately with SheetFlow.
