How FieldFix works, one button at a time.

Go to app.fieldfix.ai/sign-up, enter your email and a password of at least 8 characters, and tap Create free account. No card needed.

If FieldFix asks you to check your email, tap the link we sent to confirm your account, then sign in.

1. 1 On the first screen, What are you running?, enter the Make, Model, Year and Hours on the meter.
2. 2 Want the serial number or a photo on file? Tap Serial number and photo. Both are optional.
3. 3 Tap Next: service schedule. FieldFix looks up the maintenance intervals for that make and model.
4. 4 Keep the items you follow and tap the Track button (it shows how many you picked, like Track 6 service items), or tap Skip for now.

If no schedule turns up, you'll see Machine added. Add service items yourself from the machine's Service tab.

The main menu is Home, Machines, Diagnose, Service and Costs. On a phone it's the bar along the bottom, with Diagnose in the middle. On a computer it runs down the left side.

Your account menu is the circle with your initials (top right on a phone, bottom left on a computer). It has Past diagnoses, Plan & billing, Settings and Sign out.

A one-line status at the top, like "Everything's on schedule." Below that: Your machines with their hour meters, Needs attention with anything overdue or coming due, and Diagnose with your last diagnosis and a Diagnose a problem button.

Yes. Open app.fieldfix.ai in your phone's browser and use the browser's Add to Home Screen option (in Safari it's under the Share button). After that it opens with one tap, like an app.

Anything with an hour meter: track loaders, skid steers, minis, excavators, mulchers, dozers, tractors and the rest. Type any make. The list of suggestions is just there to save typing.

Tap the hour meter on any machine: on Home, on Machines or on the machine's page. In Log hours, type what the dash says into Hours on the meter and tap Save hours.

The meter in the sheet rolls as you type, so you can check it against the real one.

Two checks catch typos. If the number is lower than the last reading, FieldFix asks you to double-check (that's fine if the meter was replaced). If it's more than 2,000 hours over the last reading, check the decimal.

Every service reminder is worked out from the last hours you logged, so the more often you log, the closer the reminders are to real life. Each machine shows how long ago hours were logged, or Tap to log if they never were.

Tap Add a machine on Home or Add machine on Machines. The free plan covers one machine. Past that, the button reads Add a machine with Pro or Add more with Pro and takes you to Plan & billing.

On the machine's page, tap Mark as down. The button turns red and reads Down for repair, and Home lists the machine under Needs attention. Tap it again when the machine is back to work.

On the machine's page, tap the three-dot button. Edit details changes the make, model, year, serial number, hours when bought, notes about the machine and the photo.

Delete machine removes the machine and its service history, costs, notes and files. Type the model to confirm, then tap Delete for good. It can't be undone.

Good to run: nothing coming due. Service due soon: something is close. Service overdue: past its hours. Down: you marked it down. No service schedule: there's nothing set up to track yet.

On the machine's Notes tab. Notes are on every plan: type it and tap Save note.

Documents are on Pro. Tap Add next to Documents (or Add a document if there are none yet), pick a PDF or photo, choose What is it? (title, insurance, warranty, manuals and so on), and tap Save document. Fill in Expires (optional) and FieldFix flags it 30 days out.

Every service item has an interval in hours and the hours it was last done at. FieldFix compares that to the latest hours you logged. An item shows as due about 10% of its interval before it's due, then as overdue once you pass it.

Reminders are by hours only. There are no calendar-date or mileage reminders. You'll see them on Home under Needs attention, on the Service page and on the machine's Service tab.

On the machine's Service tab, tap Look up schedule to pull the manufacturer's intervals for that make and model. Tick the ones you follow and tap the Track button to add them. Items you already track are greyed out.

Tap Add item to add your own: Service, Every (hrs), Last done at (hrs) and Notes. Tap the pencil on any item to change it, or Remove to take it off.

On the machine's Service tab, tap Done next to the item. That opens Mark done. Check Done at (hrs) and Date.

Leave Add it to the service history too ticked to log it, and fill in Who did it and Cost if you want. Tap Mark done. The sheet shows when the next one comes due.

Every service item across all your machines, most urgent first. Tap Mark done on any item to mark it done today at the machine's current reading. If the work was done at a different reading, mark it done from the machine's page instead.

Items that aren't due yet are hidden until you tap the button that counts them, like Show 6 on schedule. Machines with nothing set up are listed under No schedule yet, and Recent service shows the latest work logged.

On the machine's page, tap Log service. Fill in What was done, Date, Hours, Who did it, Cost and Notes, add Photos and invoices if you have them, and tap Log service.

Yes, on every plan. In Log service, tap Scan an invoice and take a photo or pick a PDF. FieldFix fills in what was done, the date, hours, who did it, cost and notes. Check it over before you save. If it can't read it, fill it in by hand or try a clearer photo.

Every service, repair and diagnosis on that machine, newest first. Tap the pencil on a service to edit it or Delete it. Tap a diagnosis to open it.

Yes. In Settings, under Shops and dealers, tap Add a shop. Only the name is required. You can also add the phone number, Who you talk to, email and address.

Saved shops come up as suggestions in Who did it when you log service, and their phone number is one tap away in Settings. Removing a shop keeps its name on records that already use it.

On each machine's Service tab, under the service schedule, headed Daily walkaround. Each machine has its own list.

Tap Set up the walkaround. FieldFix adds a standard list: walk-around visual inspection, engine oil, hydraulic fluid, coolant, tracks or tires and undercarriage, leaks, lights and signals, horn and backup alarm, mirrors and cameras, safety equipment, seat belt, and clean windows and mirrors.

Tap the settings button next to the Daily walkaround heading to open Edit walkaround. Type a new check and tap Add, or tap the X next to a check to remove it.

Tick each item as you check it, or tap Check all. Then tap Save walkaround (it reads Save what's checked if some items are still open). Once saved it shows Saved for today. Change a tick later the same day and you can save again.

No. It's a quick daily check that helps your crew catch leaks, low fluids and broken lights before they turn into downtime. FieldFix doesn't promise compliance with OSHA or any other rule. Follow your operator's manual and whatever inspections your work requires.

1. 1 Tap Diagnose in the menu, or Diagnose on a machine's page.
2. 2 Under Which machine?, pick the machine, or tap Something else and type the make, model and year.
3. 3 In What's it doing?, describe it like you'd tell your mechanic: what happens, when it started, what you've already checked. The quick-pick buttons like "Won't start" add a starting point.
4. 4 Add the Fault code if there is one, and a photo with Take or add a photo (up to 8 MB). Photos help a lot.
5. 5 Tap Diagnose it. It usually takes 20 to 40 seconds.

Looking at your photo if you added one, then searching the web live for your exact make and model: the fault code, known issues, service info and owner fixes. You can watch each search and the sites it found as it goes.

The Most likely cause with how confident it is. A When to stop warning if it isn't safe to keep running. Check these, in this order for the other possible causes. How to fix it, step by step, with steps you can tick off. The job: rough parts and labor cost, time, and tools and supplies. And What FieldFix read, the sources it used.

Yes. Use Ask a follow-up next to the diagnosis (on a phone it's a button along the bottom). Try one of the suggestions, like "Can I keep running it?" or "What part numbers do I need?", or type your own.

Tap Log the repair under the diagnosis. It opens Log service filled in with the cause and the diagnosis date. Add the hours, cost and who did it, then tap Log service. The diagnosis itself already shows on that machine's History tab.

Past diagnoses in the account menu, or the Past diagnoses button on the Diagnose screen. Diagnoses on a saved machine also show on its History tab.

5 a month on the free plan. They reset on the 1st, and the Diagnose screen shows how many you have left. Pro has no monthly limit, with a fair-use cap of 60 a day.

Treat it as a sharp second opinion, not the final word. It can be wrong. Check torque specs, capacities and safety steps against your operator's manual before you turn a wrench, and take the When to stop warning seriously.

On the machine's Costs tab, tap Add expense. Fill in Amount, Date, Category and Notes, attach the Receipt if you want, and tap Save expense.

Categories are fuel, fluids, parts, loan payment, rental, insurance, maintenance, shop service and other.

Yes. In Add expense, tap Scan a receipt and snap a photo or pick a PDF. FieldFix fills in what it can read. Check it over before you save.

Running cost is fuel, fluids, parts, service and insurance, including service records that have a cost. Owning cost is depreciation from what you paid, or your loan and rental payments. FieldFix spreads the costs over the hours the machine has run since your first logged cost, estimated from its average use when it has to be. Log hours or it can't do the math.

Tap Check market value on the Costs tab. FieldFix searches auction results and dealer and marketplace listings for the same model and similar hours, then gives you a likely range with the Comparable machines it found. It's usually done in under a minute. Tap Check again anytime.

What the machine is worth on paper. Tap Add purchase info and enter What you paid, Purchase date, Hours when you bought it and, if you know it, what it's Worth at the end. Pick how it loses value: By hours used or By year. That also adds the cost of owning it to the hourly number.

Your fleet ranked by Cost per hour, highest first, split into running and owning. Where it went breaks down the last 90 days, and Recent spending lists the latest costs across every machine.

In Settings, under Team, tap Invite an operator. Add their email or phone if you want a record of who it's for (both optional), then tap Create invite code. Send them the code. It works for 7 days, and they sign in with it at operator.fieldfix.ai.

Only the machines you assign them. FieldFix gives them their own sign-in to log hours and checklists on those machines.

Tap Machines next to their name, tick the machines in Machines they can see, and tap Save.

Tap Remove next to their name. They lose access to your machines right away. For an invite that hasn't been used, tap Copy code to resend it or Cancel invite.

No. Team access comes with Pro, and Pro is priced per machine, not per person.

One machine, the hour meter and service reminders, service history and notes, the daily walkaround, scanning service invoices into history, and 5 AI diagnoses a month. Free for good, no card.

Unlimited machines, diagnoses with no monthly limit (fair use: 60 a day), costs and cost per hour, receipt scanning for expenses, market value, depreciation, exports, documents, team access and the API. It's $10 per machine per month. Add or remove machines anytime and the bill follows.

No. The free plan is the trial: run one machine on it for as long as you like, then go Pro when you add the second.

Open Plan & billing from the account menu and tap Go Pro. You pay on Stripe's checkout page, then land back in FieldFix on Pro.

Nothing on your bill. Existing subscribers keep their plan and their price.

On Plan & billing, tap Manage billing. It opens Stripe, where you can update your card and download invoices. If a payment fails, Plan & billing tells you, and updating your card in Manage billing keeps Pro on.

On Plan & billing, tap Cancel Pro and confirm. You keep Pro until the end of the period you paid for and won't be charged again. Change your mind before then? Tap Keep Pro.

You're back on the free plan and your machines, hours and history all stay. Free covers one machine and 5 diagnoses a month, so you can't add machines until you're back under that. Costs, market value, depreciation, documents, exports and team access lock until you go Pro again.

In Settings, tap Change password, enter a new one of at least 8 characters and tap Save password.

On the sign-in screen, type your email and tap Forgot password?. Follow the link in the email we send, then set a new password with Change password in Settings.

On Pro, tap Export on a machine's page. Pick a PDF report (hours, service and costs on one page), a spreadsheet (CSV) of service history, expenses, notes, depreciation or market value checks, or Everything (ZIP).

Yes, on Pro. In Settings, under API, tap New API key, name it and tap Create key. Copy it right away, because it's only shown once. You can have up to 5 keys.

Pro accounts get 10,000 requests a day (accounts on the older Operator plan keep 1,000). Calls today shows where you're at and resets at midnight UTC. See the API docs for the endpoints.

Tap Sign out in the account menu or in Settings.

In Settings, tap Delete account, type DELETE to confirm and tap Delete everything. That removes every machine with its hours, schedule and history, plus costs, notes, documents, photos and past diagnoses. It can't be undone. If you're paying for Pro, it stops renewing.
