The day the garage burns or the truck box disappears, the insurer asks for a list: make, model, serial, value, proof you owned it. Almost nobody has that list. The rest of the year the questions are smaller but constant: where is the impact driver, who has the chainsaw, and which battery platform is the money already in. ToolCrib is that list, kept as you go. EVERY TOOL, WITH ITS IDENTITY Name, brand and model, serial number, replacement value, a photo, the purchase date. The serial plate is usually under the battery or on the motor housing; log it once and it is on file for good. LOANS THAT COME BACK Lend a tool with a borrower and a due date you both saw. Overdue loans float to the top of the list. Mark the loan returned when the tool is back on the shelf, and keep the history of what went out and what came home. A SPOT FOR EVERYTHING Garage wall, back shed, truck box, the current jobsite. Every tool knows where it lives, so seven in the morning with the truck running is not a search party. Deleting a spot never deletes its tools. RECEIPTS AND WARRANTIES ATTACHED Photograph the receipt before it fades and keep it on the tool it proves. Warranty end dates live there too, because the end date is the difference between a free repair and a quote. THE BATTERY PLATFORM PICTURE The overview adds up which battery platforms you are already invested in, how many tools ride on each and what they are worth together. Worth a look before buying into a third one. THE INSURANCE INVENTORY PDF One document: every tool by location with serials, values and the proof on file, plus what is out on loan and with whom. Save a copy with your policy papers and hand the adjuster a document instead of a memory. PRIVATE BY CONSTRUCTION Everything stays on the device. No account, no server, no sync. Nobody else can read it, including us. FREE AND UNLOCKED Twelve tools stay free, always. The one-time unlock removes the cap and adds the insurance inventory PDF. One payment, no subscription.
