Product Design

A mobile app that allows neighbors to share tools with each other so not everyone would need to own every kind of tool.

Design Brief

Toolshare for Homeowner to Homeowner

The project prompt was to design mobile applications that leverage the crowd to achieve services, features, and experiences that are impossible with individual interaction between a person and a computational system. We had to design for Homeowner to Homeowner, allowing neighbors to share tools with each other so not everyone would need to own every kind of tool. This app should help homeowners more easily take care of their homes instead of hiring professionals to do the work.

Opportunity Space

Home improvement projects are very expensive


Home improvement projects are very expensive to outsource and expensive still when you need to buy the tools for a mere one time use. This is where ToolShare comes to the rescue. ToolShare leverages the neighborhood community to engage in a crowd sourced tool sharing activity.


ToolShare connects the people who don't have the tools with the people who have the tools. In the process we convert non DIYS into DIYs and create a user base where people meet their neighbors, exchange tools with them and create a community.


ToolShare lets the homeowners feel empowered, a neighborhood community with a spirit for sharing is formed and home improvement stores can reach their audience more effectively than ever before.


Tool Owner + Tool Borrower

Eryk Milanski, a tool owner

Eryk is our tool owner. He is an expert with tools and collects them. He is also a community veteran and wants to help people with their home improvement projects.

End Goals: Eryk wants to feel he is empowering homeowners to take care of their own homes the way he takes care of his home.

Experience Goals: Eryk does not feel comfortable using a computer for more than email. He likes iPhone but sometimes finds the text too small. He wants to feel confident when using his phone.

Ram Kuripati, a tool borrower

Ram is a novice and has no collection of tools but is interested in doing home improvement projects since he just bought his own house. He has decided to retile his bathroom.

End Goals: borrow expensive tools and look for advice on how to use them to get the work done right the first time.

Experience Goals: He wants to make any arrangements he needs ahead of time so he can get his home fixed up.

Value Flow Model

The potential market for DIYs alone is 10 million users.

The potential market for DIYs alone is 10 million users. These new DIYS will bring business to Home Depot and other home improvement merchants like it via our platform. ToolShare will help home improvement stores connect with our user base, which happens to be their relevant customers, through targeted coupons and ads.

ToolShare user base comprises of the potential customers for the home improvement stores. So the borrowers get free tools from tool owners and coupons from home improvement stores through ToolShare. ToolShare gets relevant data from the borrower requests about their supply needs and gets paid for targeted ads by home improvement stores. Home Improvement stores get new customer and increase their sales and purchases.

Scenario & Solution

Process through Iterated Scenarios

The team worked together on ideating and iterating the overall service system and the the step-by-step interface sequence catered around the two personas. Throughout the project, the team made multiple iterations and edits on the scenario. We discussed different situations and opportunities that may prompt the use of the app.

Scenario 1

Ram having done his research he knows that he needs about 5 different tools plus a tile saw and the construction materials to retile his bathroom. He has filled in the information and published the request through the app, then, he gets targeted with a coupon from Home Depot which is related to his recent request.

Scenario 2

In the evening while sitting on his couch having his tea Eryk checks his email on the phone. He opens the email from Toolshare. The email has a list of items that people in his neighborhood have requested.

He sees Rams request for a tile saw. Eryk knows that he has a tile saw in his tool collection and clicks on the email link which opens up the page showing him the request details. After reviewing the details of Ram's request Eryk clicks on the chat button and starts a conversation with Ram. He responds to Ram saying “Hi Ram……MK Diamond for you.” Eryk also shares a picture of his Tile Saw that he had already taken when lending the Tile Saw previously.

Scenario 3

Ram gets a notification on his phone about Eryk’s response which opens up the chat window. Ram writes back to Eryk thanking him for his response and schedules the exact date and time for pickup and drop off.
Eryk is presented with these details and a request for confirmation. He accepts it and both can see the transaction finalized on their chat screen. Ram thanks Eryk and seals the deal.

Later on, using this chat interface they can also coordinate the logistics of the tools return.

Scenario 4

The next day Ram goes to Home Depot to use his coupon and picks up all his remaining supplies since he is already there. At the checkout he launches the app and it automatically opens the coupon screen which uses a 3D barcode to communicate with Home Depot POS. Once scanned the coupon can be tracked back to ToolShare and Home Depot can eventually track how many new sales the platform was able to bring to them.

Scenario 5

With all his supplies and tools in hand, Ram is able to finish retiling his bathroom and is very proud of the outcome. He takes a picture and shares it with Eryk thanking him for his tile saw. "All done! Check out what your tile saw helped me do!"
