InkLine vs GHOSTLINE: an honest ghostline app alternative

GHOSTLINE and InkLine attack the same problem from opposite ends, and for a working artist the choice usually comes down to two questions: how the stencil reaches paper, and what you are willing to pay every month for it. Everything below about GHOSTLINE comes from its own App Store listing and its public customer review feed, read as of October 2026, after the ground-up rebuild it shipped as version 3.0.0.

Pick by how you print, not by feature count

Six situations, six answers. Read the one that matches yours and skip the rest.

You run a thermofax or a dedicated thermal stencil printer in a shop. Stay with GHOSTLINE. Its Pro Stencil engine has an explicit setting that tailors output for a thermofax versus an inkjet, and nothing in this comparison matches that named control. A stencil rendered for thermal transfer paper wants different line weight and different black density than one going to an inkjet, and GHOSTLINE is the only app here that exposes that choice directly. Since version 3.0.0 you also blend Pro with Classic and set line weight while the stencil redraws in front of you.

You print at home on an inkjet or laser and your recurring failure is wrong size. This is the case where switching pays. The single most common disaster in home stencil printing is a design that comes off the sheet 15 percent smaller than the client agreed to, because the print dialog quietly scaled it to fit the margins. InkLine lays the stencil out at the width or height you type, from the paper’s corner at true scale, on US Letter, US Legal, Tabloid, A4 or A3; re-tiles rather than scales when the printer turns out to have different paper; exports a PDF that carries its own page size; and prints a 5 cm check ruler on every sheet, so a scaling error shows up on plain paper before it reaches stencil stock.

You make one or two stencils a month. A monthly subscription is poor value at that volume, and several GHOSTLINE reviewers say exactly that. This is the case where InkLine’s shape helps rather than its feature list: the manual workflow is free up to an allowance on how many images you carry through it, and the paid tier that covers manual editing is sold separately from AI credits, so when you do pay you pay for editing rather than for a whole suite. Treat that allowance as a runway for evaluating the app rather than a permanent free tier: it counts images, not months, and the count is held outside the app’s own storage, so deleting and reinstalling does not reset it. Read the In-App Purchases block on either product page before you install; that is the only pre-install source that is current.

Most of your work is grayscale portrait or realism. GHOSTLINE’s reviewers rate its tonal control highly and specifically credit it with keeping detailed designs readable. That praise is consistent enough across the feed to be a real signal, not marketing.

You need stippled or dotwork tone rather than lines. GHOSTLINE’s listing describes a spectrum from line-based to value-based stencils. It does not describe a dedicated stipple output. A named Dotwork mode is a genuine difference here, and so is a Denoised mode for grainy photos shot at high ISO in bad shop lighting.

You need to invent a design from nothing. GHOSTLINE’s listing describes cut-out, upscaling, sharpening and stencil generation from artwork you already have. It does not describe generating an original design from a text prompt. If that is what you want, the two apps are not really competing.

Six stencil modes versus two stencil engines

Mode count is the easiest thing to brag about and the easiest thing to overrate. A mode you never open is worth nothing, and GHOSTLINE’s two engines cover the mainstream of stencil work competently — Classic gives you detail and intensity across a line-to-value spectrum, Pro adds contour and line-weight control and the output-device setting, and the two can be blended. Before either runs, GHOSTLINE’s Cut Out lifts the subject off its background in one tap. InkLine has no equivalent step: a cluttered background in the photo can come through extraction, and you erase it afterwards.

Linework, the default, covers the middle: solid black lines traced along the contours, with near-black areas kept as fills. The other five earn their place at the edges. Sketch gives the pencil look with gray shading kept, for sketch-style work. Outline strips it back to bare contours, the right call when you will shade freehand. Dotwork produces outlines plus stipple instead of gradient. Tonal is InkLine’s answer for portraits and realism: rather than gray that will not transfer, it draws a black-and-white shadow map, with dotted lines where each shadow level begins and hatching over the darkest. Denoised runs the line tracing on a noise-reduced copy, which matters when the reference is a phone photo taken under a shop lamp — without it, grain gets traced as fake linework. A Cleanup slider strips speckle in Linework, Sketch, Outline and Denoised, and is deliberately absent from Dotwork and Tonal, where the dots and hatching are the point.

The practical difference: with two blendable engines you tune one result until it is acceptable, and GHOSTLINE now redraws it live as you drag, which makes that tuning quick. With six modes you run the same photo through several and compare, which is faster than tuning when you do not yet know what the photo will give you. Line weight is on both sides now: GHOSTLINE’s Pro engine adjusts it as you watch, and InkLine’s print screen sets it in millimetres — fine 0.3 mm, medium 0.4 mm or bold 0.5 mm — and redraws the stencil so the typical line comes out at that width at whatever size you print. If you are unsure which fits your design, which stencil mode for which design works through it case by case.

Printing: both tile, and the difference is in the sizing

Be clear about this, because it is where competitor pages usually lie: multi-page tiling is not a differentiator against GHOSTLINE. Its listing advertises multi-page printing from 1 sheet up to 16, a multi-size sheet that puts several sizes of one stencil on a page, and saving as a PDF or as images, and its reviewers cite print scaling more than any other feature as the reason they keep paying. Anyone telling you GHOSTLINE cannot print a back piece across several sheets, or save it as a PDF, has not read the listing. InkLine has a multi-size sheet too, with four copies at 100%, 95%, 88% and 80%.

What differs is how the size is set and checked. GHOSTLINE sizes by pinch-and-zoom on the sheet. InkLine lets you pinch too, but the size is a number: you type the width or height in cm or inches, the PDF carries its own page geometry, and every sheet carries a 5 cm check ruler, which survives the trip to a laser printer at a copy shop and tells you on arrival whether anything rescaled it. Its tiled sheets also say where they go, with a label such as A1 · 1/4 and a small grid map, and each seam has a dashed cut line and three circle-and-cross registration marks. Whether that matters depends entirely on whether your printer is honest about scaling. One 1-star GHOSTLINE review, posted in October 2025 on version 1.7.2, reports a roughly quarter-inch gap appearing in tiled output on large work, forcing the artist to draw the missing strip by hand. It predates the 3.0.0 rebuild, and nothing in the review feed says whether the rebuild fixed it.

Treat that as a warning about tiling generally, not about one app. Whichever you use, print one tile, measure it against a steel rule, and tape two sheets together before you commit paper and time to a sixteen-sheet set. There is more on the mechanics in multi-page stencil tiling and on the printer-side settings in how to print a tattoo stencil at home.

Editing the stencil after extraction

Both apps accept that no automatic extraction is finished. GHOSTLINE gives you pen, eraser, a ruler tool for perfectly straight lines and a Blend tool that combines stencils or mixes the original artwork back in, with undo and redo on every change, pinch-to-zoom and canvas rotation since version 3.0.0. It also has a reference layer you can hold over the artwork mid-session, with a slider between artwork and stencil and a choice of stencil colors. InkLine has a ruler too, so for geometric and ornamental work that is a tie. The reference layer is where GHOSTLINE’s pitch is sharper: it is built to be used during the tattoo, while InkLine’s Reference view, which tints the stencil’s lines in one of six colors over the photo, is a view-only check inside the app.

The counterweight is stylus depth: full Apple Pencil support with Pen, Pencil, Marker and Eraser brushes that draw with pressure or at an even width, a stroke eraser that removes a whole line with one touch, a Colors tool, mirror and flip, a photo guide that puts the original photo under the stencil while you redraw, and a step timeline on top of stroke-by-stroke undo and redo, so a bad twenty minutes of redrawing rolls back cleanly. On an iPad with a Pencil, that is closer to drawing than to retouching. On an iPhone with a finger, the gap between the two apps narrows to almost nothing.

Cost, and the complaint that dominates the 1-star reviews

GHOSTLINE’s App Store description states plainly that it is a subscription-based app, and adds that all tools are included, with no credits and no pay-per-stencil; the app itself is a free download. As of October 2026 the pattern in its low-star reviews is consistent: people download it, meet a subscription screen almost immediately, and feel the free listing misled them. Others say the subscription is fair but would rather pay once. Against that, the five-star reviews are specific and credible — artists describing an hour a day recovered, and a studio owner calling it their default tool.

InkLine’s pricing shape is worth stating precisely rather than generously, because the same complaint would land here otherwise. It is a free download. The manual stencil workflow — processing, editing, print layout and export — is free up to an allowance on how many images you carry through it, and past that allowance it needs a subscription; there is a tier that covers manual editing on its own, without AI credits attached. AI generation runs on credits, which come with the monthly plans, and that is the one place GHOSTLINE’s model is simpler: one subscription with every tool included. Those allowances are configured remotely per install and can change without an app update, which is why no number for them appears anywhere on this site. Plan around the manual workflow, and check the In-App Purchases block on the product page for what the tiers actually cost today.

What neither app fixes

Below roughly 1000 px on the long edge, a client’s photo cannot be rescued into a clean stencil by any extraction engine. You are redrawing, not converting, and no amount of upscaling changes that; see photo resolution for tattoo stencils for the numbers. Neither app replaces a dedicated thermal stencil printer at shop volume — they replace the tracing, not the hardware. An on-skin preview is a visualization, not a measurement of how a design wraps a curved limb; InkLine’s is an AI-generated image of the design on a generic body part. And AI generation needs a network connection, which is exactly the thing a convention hall does not have; manual processing runs on-device.

If you already subscribe to GHOSTLINE and it is working, the honest advice is to keep it and test the alternative on the specific job where it fails you — usually a home-printed piece that came out the wrong size. Run both on the same photo, print both at true size, and let the ruler decide.

InkLine vs GHOSTLINE, feature by feature

What GHOSTLINE does better: GHOSTLINE was built by tattoo artists for tattoo artists and its Pro Stencil engine does the one thing a stencil app exists to do, well: adjustable contours and line weight, a live blend with its Classic engine, and an output setting tuned specifically for a thermofax or an inkjet, which no general-purpose image tool offers. Its version 3.0.0 rebuild added a one-tap cut-out, and its print layout can spread a single design across as many as 16 sheets, put several sizes on one sheet, or save it as a PDF. As of October 2026 it holds a 4.59 average from 354 ratings, and working artists in that review feed describe cutting close to an hour a day off stencil prep.

Feature	InkLine	GHOSTLINE
Cost of the manual stencil workflow	Free download. Processing, editing, print layout and export are free up to an allowance on how many images you carry through the workspace, then a subscription; a manual-only tier exists for artists who never generate. AI generation uses a credit system.	Free download, but its own App Store description calls GHOSTLINE a subscription-based app; it also says all tools are included, with no credits and no pay-per-stencil (listing, October 2026).
Stencil extraction	Six named modes on the same photo — Linework (the default), Sketch, Outline, Dotwork, Tonal, Denoised — plus Detail, Intensity and Cleanup sliders.	Two engines that blend, updating live as you adjust: Classic (detail and intensity, line-based through value-based) and Pro (detail level, contours, line weight, thermofax or inkjet output). A one-tap Cut Out lifts the subject off its background first.
Multi-page tiling	Tiles a design larger than one sheet across up to 3 × 3 sheets, with a 15 mm shared strip, three registration marks and a dashed cut line on every seam, and a label such as A1 · 1/4 on every sheet.	Also tiles. The listing advertises multi-page printing from 1 sheet up to 16, with pinch-to-zoom sizing, rotate and flip.
Paper sizing	You type the stencil's width or height in cm or inches; US Letter, US Legal, Tabloid, A4 or A3 at stated dimensions, portrait or landscape, with a 5 cm check ruler on every sheet. A multi-size sheet prints four copies at 100%, 95%, 88% and 80%.	Paper size and orientation selection with pinch-to-zoom scaling on the sheet, and a multi-size sheet with several sizes of the same stencil; reviewers cite print scaling as the feature they subscribe for.
Output to a printer	Prints directly to AirPrint printers from iPhone or iPad, re-tiling at the same size if the printer has different paper; PDF export at the chosen paper size, and PNG with an optional transparent background.	Prints with AirPrint, or saves the stencil as a PDF or as images to print later; exports to Photos, Files or any app at any stage.
Stylus editing	Full Apple Pencil support, Pen / Pencil / Marker / Eraser with pressure or even width, a stroke eraser, a ruler, a Colors tool, stroke undo and a step timeline you can move back along.	Pen, eraser and ruler tools, plus a Blend tool that combines stencils or mixes in the original artwork; undo and redo, pinch-to-zoom and canvas rotation since version 3.0.0. The listing does not mention Apple Pencil by name.
Reference overlay	A photo guide puts the original photo under the stencil at 0–90% opacity while you draw, never printed; a separate view-only Reference check tints the lines over the photo.	Reference tool shows the stencil as an adjustable layer over the artwork while you tattoo, with a slider between artwork and stencil and a choice of stencil colors.
Generating an original design	Text prompt to design or to stencil, photo to stencil, stencil to full color, and the design shown on a generic body at one of 10 placements; 16 styles; needs a network and a credit per result.	Cut-out, upscaling that adapts to photos or line art, and sharpening of artwork you already have; the listing does not describe generating an original design from a text prompt.
Platform and track record	iPhone and iPad, iOS 17+, version 1.1.0, ships in 8 languages.	iPhone and iPad, iOS 17.0+, version 3.0.0 (October 13, 2026, a ground-up rebuild), first released December 2022, 10 languages, 354 ratings at 4.59.
