Scale Model Kit & Paint Log — A build tracker and paint shelf for more than one kit on the bench

A model-building tracker earns its keep when more than one kit is in progress: it needs to hold the whole stash, follow each build through real stages, and know what paint is actually left before a coat starts. Scale Model Kit & Paint Log covers all three — a kit shelf across eight categories, a ten-stage build tracker with sub-assemblies, and a paint inventory with stock levels. It's free on Android, with iOS coming.

Most builders end up with kits at very different points: some still in shrink wrap, some mid-build, some just bought on impulse. Sorting the stash by status — owned, backlog, wishlist or built — rather than only by subject matter is what keeps a growing shelf from turning into a guess. Scale Model Kit & Paint Log's kit shelf uses exactly those four statuses, alongside category and scale.

A common sequence runs planning, assembly, seam cleanup, priming, painting, panel lining, decals, topcoat and weathering, finishing at a completed build — though not every kit uses every stage, and finish style (clean, battle damage, camouflage) shapes how much weathering happens. The app's Build Tracker follows exactly this ten-stage sequence, with sub-assemblies so a cockpit or turret can progress separately from the main hull or fuselage.

A glued joint between two plastic parts leaves a seam line, and sanding or filling it before primer goes on is what keeps that line from showing through the finished paint job. Skipping from assembly straight to painting is one of the most common shortcuts that shows up later as a visible ridge. The build tracker keeps seam cleanup as its own stage, separate from assembly and priming, so it doesn't get skipped.

The honest answer is logging each bottle's level rather than trusting memory, because a half-used bottle of a specific color code looks identical to a nearly empty one from across a shelf. Scale Model Kit & Paint Log's paint inventory tracks brand, color code, type and a full, half, low or empty level per bottle, and Bench Check looks at the bottles assigned to a project before each build stage.

Yes. Unlimited kits, builds and paints, every tracker and timer, 8 Build Master plans and 4 AI bench tasks a month, and one Vision Feedback preview are free, and the free version shows ads. Pro adds unlimited Build Master plans and AI bench tasks, up to 30 photo critiques a month, and no ads.

Not yet. The app is live on Google Play; the App Store listing is set up but the iOS app hasn't launched there yet. The Android app already covers the full kit shelf, build tracker and paint inventory.

Describe the kit, pick a finish and your skill level, and it returns a step-by-step build plan with a materials list, drawing on the paint names already logged in your inventory and flagging what's still missing. It's general hobby guidance built from common build practice, not a replacement for the specific kit's own instruction sheet, which the app explicitly says to keep checking.

It's a feature aimed at the kit that's been sitting untouched rather than the one just started: pick a stalled project from the shelf, and the app suggests one small bench task to do tonight instead of asking for a full session. The idea is lowering the bar back into a project rather than demanding a long return to the bench.

The kit shelf, build tracker and paint inventory are stored on the phone with no account required — you start as a guest, and there's no cloud backup. A connection is only needed for the optional AI features: Build Master, AI bench tasks, and Vision Feedback, which send only what each one needs — kit details, finish, skill level, paint names, or a progress photo if you allow it — through the app's own server.
