Know what to order. Know what to quote. Keep the job moving. BrickCal gives contractors, estimators, builders, and serious renovators one field toolkit for construction calculations, saved project work, and client-ready quotes. Enter the measurements you have, get usable quantities, save the result, and carry the job forward without rebuilding the work in another app. Use BrickCal to: - Get material estimates for brick, concrete, steel, rebar, gravel, mortar, paint, tile, drywall, flooring, roofing, stairs, fencing, excavation, waterproofing, and more - Use electrical, plumbing, HVAC, lighting, wire size, pipe flow, gas pipe, fire sprinkler, ventilation, solar, and other MEP helpers - Work from 60+ construction calculators and jobsite tools in one catalog - Save calculations, recent inputs, history, and project folders so repeat work is easier to resume - Build project quotes with line items, labor, overhead, markup, tax, discounts, terms, and client or project details - Prepare and share cleaner quotes and reports when PDF export access is available - Switch between metric and imperial units - Find tools quickly with search, categories, My Apps, and recent tools - Use supported-device field tools such as bubble level, inclinometer, compass, protractor, surface level, and noise meter A typical job can stay in one flow: measure the work, calculate what you need, save the result, reopen it later, and turn the numbers into a clearer client conversation. Access is flexible. Some tools and PDF export actions may use optional purchases, credits, ads, rewarded access, or an entitlement. Available options and prices are shown in the app. Local project, quote, slot, and PDF-credit data stays app-owned unless you export or back it up. BrickCal is planning support, not a substitute for local code checks, licensed trade judgment, field verification, engineering review, supplier specifications, or current pricing. Verify the job before ordering materials, committing a price, or sending work to a client. Download BrickCal before your next takeoff, material order, site check, or client quote.

TURN A DAY'S WORK INTO A PAID INVOICE. HAMMR is the offline-first invoice maker, estimate app and job tracker built for handymen, independent contractors and tradespeople. Clock in at the job site, log the work as it happens, and send a clean PDF invoice before you leave the driveway. FROM CLOCK-IN TO PAYMENT - Start a live timer for each job and see hours and earnings as you work. - Log mileage, materials, receipts, notes and site photos in one job record. - Pin your location at clock-in and capture a client's on-site signature. - Keep working without a signal. HAMMR saves everything on your device first. ESTIMATES AND INVOICES - Create a professional estimate before the work starts. - Mark it approved or declined, then convert an approved estimate into an invoice. - Build invoice line items from labor, mileage and materials, or add custom charges. - Apply tax and flat discounts, set due dates and generate a polished PDF. - Share estimates and invoices through Mail, Messages or any app in the iOS share sheet. KNOW WHAT IS PAID - AND WHAT IS NOT - Record deposits and partial payments while HAMMR tracks the remaining balance. - See collected revenue, outstanding invoices, overdue balances and unbilled work. - Add Venmo, PayPal or Cash App payment links and QR codes, plus Zelle or check details. - HAMMR never processes your client's payment, so it adds no payment gateway fee. READY FOR TAX TIME - Review tax collected, material spend and month-to-date or all-time totals. - Export a clean CSV for your accountant. - Export a PDF bundle of invoices, including signed copies. BUILT FOR INDEPENDENT TRADES HAMMR fits handymen, plumbers, electricians, painters, landscapers, carpenters and other solo contractors who need a simple field tool - not a heavy office system. YOUR WORK, YOUR DATA Core job tracking, invoicing and exports work on-device. Create a full JSON backup whenever you need it. HAMMR Pro adds optional cloud backup and multi-device sync after you sign in with Apple or Google. Download HAMMR and move from clock-in to invoice without rebuilding the day from memory. HAMMR Pro is available as a monthly auto-renewing subscription or lifetime purchase. Pricing is shown before purchase. The monthly subscription renews unless canceled at least 24 hours before the end of the current period. Manage or cancel it in your Apple ID settings. HAMMR is a record-keeping tool, not accounting, tax, legal or payment-processing advice. You are responsible for the records and payment details you create.
