I posted BuildWalk here in June: a contractor records a voice walkthrough on site and gets back an estimate PDF with line items and a labor/materials split. Three months of feedback and a few releases later, here is what changed. The objection that stuck came up twice, from different people: the words are fine, the numbers are a guess. Someone says "bathroom, about eight by ten" and every line in that quote carries the "about". Nobody wants to bet a bid on it. So the app now scans the room. Point the phone, walk it, and it pulls the floor area, the wall area, the doors and the windows, subtracts the openings, and feeds those quantities into the estimate. No LiDAR on your phone means you type the dimensions instead and land in the same place. Two smaller things: - You can snap photos during the walkthrough and the app describes each one (room, materials, condition, visible defects), so the write-up has what you saw and not only what you said. - The first run no longer starts with a six-field project form. One tap and you're recording. New accounts also get a sample project with a finished estimate, because half of my signups never recorded anything and I think that form is why. What I learned building the scanner: - Summing the individual walls a scan returns gives you too much wall. The API hands back overlapping and duplicated surfaces, so the honest number is the perimeter of the floor outline times the ceiling height. - The scan is the easy half. Deciding what a scanned room means for a quote is the product: which trades get charged by floor area, which by wall area, and what a doorway removes from both. - I checked one real bathroom against a tape measure before shipping it. That's one room, not a study, and I say so when people ask about accuracy. iOS, free 14-day trial: https://apps.apple.com/us/app/buildwalk/id6762346853 https://buildwalk.app/?utm_source=reddit&utm_medium=social&utm_campaign=oct_w1&utm_content=sideproject Still solo, still $0 on ads, still no paying users to brag about. If you estimate work for a living I want to hear where the measured numbers are wrong for your trade.   submitted by   /u/AdKey4749 [link]   [comments]
