Grainger is the Android app for W.W. Grainger, Inc. It is free, carries no ads and offers no in-app purchases, and it exists to put the company's catalog and account tools on a phone rather than a desktop. The catalog alone is the headline: more than a million products to search and compare.
That scale is the reason to consider it. If you order fasteners, safety gear, tools or janitorial supplies for a building, a shop floor or a job site, the appeal is being able to look something up and act on it without being tied to a computer. The app has been on Play since June 2012 and sits at a 4.6 average from 6,771 ratings, with over a million installs.
What I find most interesting is how much of the app is built around the moment of purchase rather than browsing. Availability, branch pickup, barcode scanning and approval queues all point to someone who already knows roughly what they need and wants to confirm it quickly. That framing shapes everything below.
Availability is the feature the app leads with
The first thing the developer highlights is real-time availability. For a given item you can get an expected arrival date, or see whether it is in stock at a branch near you. For anyone ordering against a repair that cannot wait, that distinction matters more than a product photo or a spec sheet.
This is the part of the app I would expect to earn its keep. Knowing an item is on a shelf twenty minutes away changes the decision from ordering to collecting, and knowing it is not saves a wasted trip. The developer frames this as availability information rather than a guarantee, and I would treat it that way: useful for planning, not a substitute for a phone call when the stakes are high.
It pairs naturally with the branch finder, which locates the nearest location for quick pickup. Together they cover the same question from two directions, and for a maintenance technician mid-shift that is the practical core of the app.
The supporting tools around the order
Barcode scanning is the feature I would reach for most often. Scan a product and it drops straight into your cart, which removes the guesswork of matching a part number by hand. When you are reordering something you are holding, that is a shorter path than typing a string of digits into a search box.
Voice search is offered for the moments when your hands are full or you simply speak faster than you type. Product search by voice is a small convenience, but on a ladder or under a hood it is the difference between ordering now and ordering later.
Lists stored on Grainger.com can be pulled up in the app for quick reordering, which suits repeat buys: the consumables, gloves and filters that get used up on a schedule. Order history covers the last 18 months regardless of how the order was placed, so a purchase made by phone or at a counter still shows up alongside app orders.
Order status sits in the same place, and pending orders waiting on your approval are tracked in the app. If you are the person who signs off on purchases, that queue is the reason to keep the app on your phone rather than checking in from a desk.
KeepStock and the inventory side
KeepStock is the piece that goes beyond ordering. The developer describes it as an inventory management system for tracking and controlling what you spend on stock, and it is pitched as agile, which I read as suited to sites where demand shifts rather than a fixed annual plan.
For a facilities manager or a small operations team, that is a different job from buying a single part. It is about knowing what is on the shelf, what gets consumed and what it costs to keep it there. The app gives that work a mobile entry point, which matters when the shelves are not next to a computer.
I would not expect an inventory system folded into a shopping app to replace dedicated software for a large warehouse. What it does offer is a way to check and act on stock levels in the same place you place the order, which is a sensible pairing for smaller operations.
What it asks of you
The app is free to download and there are no ads and no in-app purchases to work around. That is straightforward, and it means the cost question is about what you buy, not what you pay for the app.
Guest checkout is supported, so you can order without setting one up. Account pricing and the approval queue only make sense in the context of a business account, so the fuller experience is for people ordering on behalf of an organization.
KeepStock is an inventory management solution, which implies a level of commitment beyond casual buying: stock to track, consumption to record and costs to watch. The app is built for that kind of work rather than for a one-off purchase of a single tool.
You will also need a connection for the parts that depend on live data.
Getting the most from it on a work day
The pattern I would suggest is to let the app answer the question before you commit to a trip. Check availability first; if the item is at a nearby branch, the branch finder tells you where to go, and pickup avoids waiting on delivery.
For anything you buy repeatedly, build a list on Grainger.com and keep it handy in the app. Reordering from a list is faster than searching again, and it reduces the chance of ordering the wrong variant of a part you have bought before.
When a product is in your hand, scan it rather than typing the number. When you are unsure whether a part is the right fit, the chat option lets you upload a photo and get an answer from a specialist, which is a better use of a few minutes than ordering something you will have to return.
If you approve purchases for others, check the pending orders view before you leave for the day. And if you are new to the app, guest checkout means you can place a first order without committing to an account setup.
A practical tool for people who order for a living
The Grainger app is a companion for an existing supplier relationship, not a general shopping app. It is free, ad-free and free of in-app purchases, and it covers searching a catalog of over a million products, checking availability, finding a branch, scanning items into a cart and tracking orders and approvals.
It suits maintenance technicians, facilities staff, tradespeople and small operations teams who already buy through Grainger and want to do it from a phone. The KeepStock inventory tools extend that to people responsible for stock levels and costs, and the expert chat and photo upload help when a part needs confirming before you buy.
I would install it if Grainger is where your supplies come from and you want the catalog, the branch stock and the order queue in one place.
The short verdict
A free, focused companion for Grainger customers who need to check stock, scan parts and manage orders from a phone.

W.W. Grainger, Inc.: frequently asked questions
Can I order from the Grainger app without an account?
Yes. Guest checkout is supported, so you can place an order without setting up an account first. Account pricing and the pending orders view are tied to a business account, so those parts of the app apply once you are ordering on behalf of an organization.
How does the app help me find out if a part is in stock nearby?
It shows real-time availability, so for a given item you can see an expected arrival date or whether it is available at a branch close to you. The branch finder then locates the nearest location for quick pickup. Together they let you decide between collecting an item and waiting for delivery.
What does KeepStock do in the app?
KeepStock is an inventory management solution for managing, tracking and controlling what you spend on stock. It is meant for sites that need to keep an eye on consumption and cost rather than for a single one-off purchase. The app gives that work a mobile entry point.
How far back does my order history go?
Order history covers the last 18 months. It includes orders regardless of how they were placed, so purchases made by phone or at a branch appear alongside those made in the app. You can also check the status of a current order from the same place.
Is there a way to get help choosing a product?
The app includes a chat option with a specialist. You can upload a photo as part of the conversation and get an answer on the spot, which is useful when you need to confirm that a part is the right one before ordering. It is one of several tools built around the moment of purchase rather than browsing.
