Sprone is a design studio for one person, on the iPhone. It designs ads, social posts, stories, banners, posters, thumbnails and print for you, and learns your taste as you choose among the styles it draws.

What can I make with Sprone?

Instagram posts and stories, reels, Pinterest pins, LinkedIn and X posts, YouTube thumbnails and banners, display ads, album art, business cards, postcards, invitations, flyers and posters: 37 sizes in all, each with a layout of its own.

Do I need to sign up?

No. Sprone has no sign-in. Open it and start a design.

Does Sprone work offline?

Yes. Everything Sprone does happens on your iPhone, and its fonts, palettes and elements ship inside the app.

Does Sprone save to my photo library?

No. Sprone opens Photos only through the system's picker when you import a picture, and never writes to your library. Designs leave as files, through Files and the share sheet.

Can I use what I make for my business?

Yes. The designs you make are yours, and the fonts and graphics inside Sprone are licensed for use in them, commercial work included. Pictures, logos and references you import need to be yours to use.

Magic Creation

A finished design at the press of a button

Magic Creation is the first thing you see in every design. Each press draws a new style, so you rarely need to adjust anything by hand

Surprise me

A new style each time, never one you’ve seen in this visit

Swing

One bold move: a striking color, typeface, layout, background, frame or elements. Touch and hold to choose which

Narrow Down

Small changes to the style you’re on, until there are none left

Show Six

Six styles at once. Tap one to try it, or Six More for others

Feel

From Minimal to Maximal

A feel tells Sprone how much to bring to a design, from type and space alone to ornaments, frames and textures. Tap one, and every style follows it. Sprone can also suggest a feel from your text and product photos

Minimal

Type and space alone, in a clean sans and calm colors
Simple

A rule or a seal now and then, and seldom a frame
Elegant

Serifs and scripts, classic ornaments, fine frames and calm colors
Bold

Heavy and condensed type, strong colors and hard shadows
Playful

Retro and hand-drawn type, bright colors and fun shapes
Decorative

Ornaments and shapes most of the time, with frames and textures
Maximal

As much as each design can hold, in display type and vivid colors

What’s it for?

Every design asks for what it needs

Choose what a design is for, then fill in what that design carries. Sprone sets each field where a designer would, never broken and never past its room

Add 3 to 6 photos of what you sell, and Sprone suggests a feel, elements that suit them and colors from your products. They’re checked on your iPhone and aren’t kept once the design is made

Brand

Your brand in every style

Keep your brand’s colors, fonts and logo in one place, and every style Sprone draws keeps them. Make a brand by hand, or let Sprone learn one from posters and designs you import

As you choose styles, Sprone leans toward what you like, and every style can still come. Each brand keeps a taste of its own. A design Sprone made that you never chose teaches it nothing, and you can forget your design taste in Settings whenever you like

Ready for the press

Business cards, postcards, invitations, flyers, posters and album art, at their real paper sizes. Export a PDF or PNG with bleed, crop marks and 300 or 600 dpi

The background runs past each edge, so no white shows where the paper is cut, and crop marks at each corner show the printer where to cut

Versions

Every version kept

Sprone keeps every version you save, and the ones you keep with the bookmark. Compare two with a line you slide across the design. Restoring a version keeps the one it replaces
