The platform is paid for by hundreds of leading brands that believe you deserve a better experience with their products. These participating brands provide 3D instructions as a service because BILT app users are happier with their purchases and have fewer returns. It’s a win-win! NO SIGN IN! You do not need to provide any personal information or create an account to use BILT. We’re serious about making it easy. But there are benefits to creating a BILT app account: - Save your receipt - Register a product - Access warranty information - Keep downloaded instructions in “My Stuff” to access later - Leave a rating & review to help your favorite brands improve their products over time AWARDS - Most Innovative Construction Tool, National Association of Home Builders - Gold Winner, User Experience Awards - Winner, Pro Tool Innovation Awards BILT TOOLBOX The BILT Toolbox is a collection of instructions to help you with home, auto, and safety projects, as well as guides for basic power tools. Follow easy BILT instructions to fix a toilet, lay bathroom tile, paint a room, jump a car battery, change a tire, use a circular saw, adjust a bicycle, repair drywall, and so much more to help with anything adulthood sends your way. We use the BILT Toolbox too, so if we have a question about something, we design an instruction for it. We welcome your suggestions, too. From personal experience we recommend downloading “How to Jump a Car Battery” before you need it because internet connections at soccer fields can be spotty. :) DATA PRIVACY We do not collect personal data other than what you choose to provide if you create an account, register a product, or leave a review. We do collect aggregate data such as the number of downloads for each product and the average time it takes to complete an instruction step, but it cannot be tied to an individual user. FEEDBACK FROM OUR USERS - “I really like putting things together, but the BILT app made it a breeze! A fun little activity and a great outcome. I’m a visual learner so I really appreciate a 3D option with parts clearly labeled!! I could build a million things with the help of this app particularly. Highly recommend!!!” - "I'm telling you, I could easily engineer a space craft if they had the directions on BILT." - "I usually shy away from putting stuff together but this helped me a lot. I’m proud of myself.” - “Made it very easy, I didn’t cuss or throw anything.” - “My husband & I are NOT handy people. However, with the BILT app we were able to correctly put together a grill in a couple hours with NO arguments! LOL! This app may have saved our marriage. I highly recommend this app.” - "Extremely easy and very convenient. Thank you for making my life a little bit easier." - “For someone who is an auditory learner, this is great. Thanks. Love that I can review assembly instructions even before it ships and then use the app once things are unpacked. Plus, it will always be there should I ever need it again. Just brilliant!” Do it right the first time and download BILT now!
