How it works

From photo to fi[x]in,
in four steps.

Every repair in fi[x]in for iPhone and iPad follows the same path: you show the app the problem, it tells you what it thinks is wrong and how sure it is, it hands you a step-by-step guide, and it works through the job with you. The diagnosis runs on your device — no upload, no signal required.

The fixin home screen — a viewfinder reading "Point at the problem" above a Scan button, with Car, Home and Boat shortcuts and recent diagnoses below
Step 01

Point at the problem.

Open fi[x]in and photograph the problem — a warning light, a leak, a cracked fitting, a stain on a ceiling. The home screen is the camera: a viewfinder, one Scan button, and the option to describe the problem in words instead if a photo won't tell the story.

The image is classified on your device by fi[x]in's named ML engine — Sapphire 4.8 and Emerald 5.3 are the newest. Nothing is uploaded to identify it, so the analysis works the same in a parking garage or a boatyard with no signal as it does on wifi. You don't need an account to start.

  • Automotive, marine, and home systems in one pass
  • Runs fully offline — the photo never leaves the phone to be classified
  • What you type or dictate feeds into the diagnosis itself on cars

Step 02

Receive your diagnosis.

Classification comes back with the domain and the diagnosis named outright — here, a car with engine issues, serious enough for a warning not to drive it — and how strongly the photo actually matched it. When naming a specific fault would be a guess, fi[x]in stops at the category and says so. From there the screen becomes the hub for the job: repair instructions, the tools and supplies to have on hand, and support options.

What sits below that adapts to the domain. A car adds roadside help and a recall lookup; a boat adds Emergency Help for when you're in danger on the water; a home adds water, gas, and breaker shut-off guidance. Assign the diagnosis to a project and it files itself with the other work on that boat, vehicle, or house.

  • Match strength in plain language — Strong, Possible or Low — instead of a raw percentage
  • A severity rating on every result
  • Faults that can make it unsafe carry a warning to stop and have it checked first

Step 03

Open the repair guide.

From the diagnosis, fi[x]in opens a step-by-step guide from its library of 2,262. Safety comes first, then the ordered steps, then the tools and supplies to have on hand.

Every built-in guide comes in three levels of detail. Beginner starts with visual checks and clear points to stop and call a pro; Pro / Tech goes straight to diagnostics, testing, and checking the repair afterward. Pick yours in Settings, under Repair Guides.

  • Opens with the diagnosis it was written for, so you can see what it assumed
  • Beginner, Intermediate, or Pro / Tech detail
  • Tools and supplies listed before you start

Step 04

Execute the repair, then follow up.

The instructions become a worksheet you actually work from. Tick each step off as you go and the progress ring tracks the job; reorder steps, edit the wording for your own setup, or add a step the guide didn't know about. The worksheet here is a different job entirely — tracking down a dashboard warning light — because the four steps don't change with what you're fixing.

A suggested next step appears as you work, drawn from what you've already ticked off, and a Repair Assistant tip sits beside it. The finished worksheet stays attached to the project — so next season there is a record of what was done.

  • Checkable steps with live completion progress, and a suggested next step as you go
  • Reorder, edit, or add steps as the job actually goes
  • The record stays with the project it belongs to
