Can it pull data from OctoPrint or Klipper automatically?

It can, over the local network, and it is the obvious version-two feature — but it is also a large jump in scope, needs a host reachable from the phone, and breaks the moment someone prints from an SD card. Ship manual logging with aggressive prefill first, and treat automatic capture as an addition for the subset of users running a networked host.

How should partial failures be recorded?

As a distinct outcome rather than a boolean, because "it finished but the top layer is rough" is the most common real result and it carries the most information. Pairing a partial outcome with a short structured failure reason gives you something you can filter on later, which a free-text note never provides.

How to Build a 3D Print Log App with AI (2026)

What a 3D print log app needs

Print log with settings, outcome, and a photo
Filament inventory tracked by remaining grams
Per-material profiles that carry forward
Printer maintenance intervals by print hours
Cost per print from filament, power, and time

The screens

Screen	What it does
Prints	History with outcome badges and the model printed
Log Print	Model, printer, filament, profile, duration, outcome
Filament	Spools with remaining grams and a low-stock flag
Printers	Each machine with print hours and maintenance due
Print Detail	Full settings, photo, failure reason, and cost

The data model

Printer: name, model, nozzleMm, totalPrintHours
Spool: brand, material, colour, gramsTotal, gramsRemaining, price, openedAt
Profile: material, nozzleTempC, bedTempC, speedMmS, notes
Print: printerId, spoolId, profileId, modelName, durationMinutes, gramsUsed, outcome (success | partial | failed), failureReason, photoUri, printedAt
MaintenanceTask: printerId, title, intervalHours, lastDoneAtHours

The build prompt (copy this)

Paste this into ShipNative and it becomes a working React Native app with these screens, navigable in a live preview, in about two minutes:

“A 3D printing log. Logging a print records the model name, which printer and spool were used, the temperature and speed profile, the duration, the grams used, and an outcome of success, partial, or failed with a failure reason chosen from a short list — first layer adhesion, warping, clog, spaghetti, ran out of filament. Grams used decrements the remaining weight on that spool automatically, and a spool below a threshold shows as low stock on the filament screen. Profiles are per material and carry forward, so logging a second print with the same filament prefills the settings that worked last time; that prefill is the feature that makes the logging habit stick. Printers accumulate print hours from logged durations, and maintenance tasks are defined by an interval in hours — lubricate rods every 100, replace nozzle every 500 — showing as due against the accumulated total rather than a calendar date. The print detail screen shows a cost computed from grams used at the spool price plus an optional power cost from duration and a rate the user sets. Screens: Prints, Log Print, Filament, Printers, Print Detail. Works offline.”

Then iterate with small, screen-specific prompts (“make the primary button bigger”, “add an empty state”), preview on your own phone, and export the full Expo project whenever you want. The full method: how to build an app with AI.

How it makes money

A one-time unlock ($5-10) for multiple printers and full history suits an audience that already spends on hardware and dislikes subscriptions. Realistically most hobbyists log nothing at all, so the growth constraint is habit rather than price — which means prefilled settings and two-tap logging matter more to revenue than any pricing decision.
