Run your business from the truck.
Bit & Grain for iPhone is on the App Store, and Bit & Grain for Android is on Google Play. On any phone, the mobile-first web app runs the whole product: every page is built to work one-handed on a 6-inch screen at the job site.
The iPhone app
Download Bit & Grain from the App Store and sign in with the same account you use on the web. Your jobs, clients, estimates, and invoices are already there.
A native app does things a browser can't: trip tracking that keeps recording while the app is in the background, and push notifications you control from your iPhone's settings.
Desk work, like your website, marketing campaigns, team roles, and reports, stays in the web app; sign in with the same account on any computer.
- Jobs, clients, estimates, invoices, recurring invoices, and change orders.
- Receipt scanning with the camera.
- Trip tracking: tap Start Trip before you head out and End Trip once you're parked. The route and miles keep recording in the background, so there's nothing to touch while you drive.
- Appointments and your daily route.
- Grain AI: type a question or hold to talk.
- Your messages inbox, with push notifications for new client messages and upcoming appointments.
- Purchase orders, suppliers, subcontractors, warranties, and safety data sheets.
- Job templates, leads, and review requests.
On any phone, the mobile-first web app
Bit & Grain's web app is built mobile-first. Open it in any phone browser, save it to your home screen, and you have the whole product on hand, jobs, clients, estimates, invoices, route, command center.
Photo capture, voice chat with Grain AI, signature capture, and offline-tolerant note entry all work in the mobile browser. Login state persists, so you're not signing in every time you start a job.
- Mobile-first responsive layout, every page renders correctly on a 6-inch screen.
- Camera capture for receipts, job photos, and signature collection.
- Voice mode in Grain AI chat, log mileage, log receipts, ask questions, all hands-free.
- Add to home screen for one-tap access, no separate login each time.
The Android app
Get Bit & Grain on Google Play and sign in with the same account you use on the web. Your jobs, clients, estimates, and invoices are already there.
A native app does things a browser can't: a time clock that keeps counting in a notification, a home screen widget and a Quick Settings tile, trip tracking that keeps recording while the app is in the background, and push notifications.
Desk work, like your website, marketing campaigns, social posting, team roles, and billing, stays in the web app; sign in with the same account on any computer.
- Jobs with a punch list, materials, time, files, and a P&L on every one.
- A time clock that keeps counting in a notification, a home screen widget, and a Quick Settings tile.
- Appointments, routes on a map, and a day of stops turned into mileage.

- Change orders with client approval and signature.

- Trip tracking with GPS: tap Start Trip before you head out and End Trip once you're parked. The route and miles keep recording in the background, and the deduction is worked out for you.
- Purchase orders, suppliers, warranties, subcontractors, and safety data sheets.
- Grain AI: type a question or hold to talk.
- Push notifications.
Why the web came first
The web is universal. Whatever phone, tablet, or shop computer you're on, the same product loads instantly with no install. That's the right starting point for a tool you'll touch a hundred times a day.
The phone apps exist because some workflows, like background trip tracking, a time clock that keeps counting, and push notifications, genuinely need the OS underneath. The iPhone app shipped first, and the Android app followed on Google Play in October 2026.
