BuildCrux is AI construction estimating software for remodelers and small general contractors. Drop a PDF drawing set in — residential remodels, restaurants, dental fit-outs, retail buildouts, medspa, clinics, or pharma compounding centers — and walk out with priced line items inside the dollar range a senior commercial estimator would quote, in twelve minutes. THE WEDGE — AI ESTIMATING THAT ACTUALLY WORKS • Multi-pass pipeline on PDF drawing sets up to 500 pages • Residential + commercial TI: restaurants, dental, retail, medspa, clinics, pharmacies • Sub-bid scope filter — estimate only the kitchen, only the millwork, only the MEP (built for trade contractors bidding into a GC) • Validated against senior-estimator dollar precision: $686K on an 80-page pharma compounding center vs the $700K–$850K human-estimator reference range, with 48 line items • Non-drawing pages (energy reports, specs) auto-filtered out of takeoff • Cover-sheet auto-extracts address for project naming A FULL CONTRACTOR WORKSPACE, INCLUDED The estimating engine ships inside a complete workspace — win the bid and run the job from one platform. PROJECTS — Track unlimited jobs with status (estimating, in progress, on hold, done), client info, timelines, tasks, team assignments. INVOICES & PAYMENTS — Build line-item invoices, send secure payment links via email or SMS, auto-track paid/pending/overdue. CONTRACTS & E-SIGN — Generate from templates, send for signature, store signed PDFs alongside the project. Multi-signer support.

The live distance and timer reconnect to the trip that was recording in the background. - Ending a trip is more reliable on a weak signal: BuildCrux now retries automatically and shows a clear message instead of a cryptic error if something goes wrong. - Added a heads-up when "Precise location" is turned off, since approximate location is too coarse to measure miles accurately. - Signing out is instant, even on a slow connection. ### 1.0.1 — 2026-06-12 Bug fixes: - The mileage tracker now picks your active trip back up when you return to the app mid-drive. Your miles were always recorded in the background, and the live view now reconnects to them. - Signing out is instant, even on a slow connection. - Improved subscription reliability. ### 1.0 — 2026-06-10 No release notes. ## Apps similar to BuildCrux | App | Rating | Price | Category | | --- | --- | --- | --- | | [CCAW](https://appshunter.io/ios/app/ccaw/id6471973979) | — | Free | Business | | [Quo (formerly OpenPhone)](https://appshunter.io/ios/app/quo-formerly-openphone/id1241817309) | 4.4 (10,788) | Free | Business | | [Currency Converter](https://appshunter.io/ios/app/currency-converter/id326884235) | 3.3 (69) | Free | Business | | [GoDaddy Commerce: POS Payments](https://appshunter.io/ios/app/godaddy-commerce-pos-payments/id1152717397) | 4.7 (15,963) | Free | Business | ## More apps by Tack On LLC - [Tack On](https://appshunter.io/ios/app/tack-on/id6740439365) - [TackOn FSM](https://appshunter.io/ios/app/tackon-fsm/id6747401060) All apps by Tack On LLC: https://appshunter.io/developer/1789977887 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
