Series is a great iOS photo app that assists you in creating interesting arrangements of your photos to be published on social media, and it is becoming a "must have" companion app for people posting their photos to Instagram Threads. You can see images full screen on Threads, and, with proper formatting, share full-screen seamless panoramas of your photos as well.

It has already persuaded some users to test this new format. For instance, artist Pete Halvorsen used the diverse aspect ratios and split the photos so users could just click through them in full screen mode and swipe through.

This, in turn, prompted Series developer Ryan Carver to add new tools — specifically a tool called TH+ — to cater to the needs of Threads users to make this process easier.

Carver has a background in photography and design, including previously leading product development at photo-sharing app VSCO, and co-founding Typekit, which sold to Adobe, now Adobe Fonts. But for the past four years, he has been working as an independent iOS developer, focused mostly on Series.
The original inspiration for the app actually came from his own photography, curating and designing a gallery show in 2019

Out of that experience, two things I wanted: One is better tools to explore more visual relationships between images. Two, make it a lot easier to share a set of multiple images, he said. The canvas for this was the Instagram Carousel; it's so great for sharing multiple images in unique layouts, as he noted.

He originally developed Series as a tool that could design for the Instagram carousel and other social media, such as TikTok. The app offers a variety of tools to blend photos and videos together, combined with features like easy margin and edge controls, so users can utilize layered photos or videos as backgrounds, flexible layouts for storytelling through Diptychs and Triptychs, and shares carousels to name just a few.

The best way to use Series is to add several photos and then explore the different layouts it offers to tell your visual story — like photo pairings, stacks, grids, and carousels.

But because Threads was designed to display full-screen panoramas, Carver adds a new TH+ Frame Ratio to Series just days after Threads launched to the public, he says. Since then, Meta employees, including CTO Andrew Bosworth (@boztank), have discovered and used the feature, and Bosworth himself posted an impressive Everest Pano that gathered over 7,000 likes and 180 replies.

Since this update, many users on Threads have begun experimenting with the pano option. They do this by capturing one image and then stretch it across several panels so users have to swipe through the image.

Some people put the full image at the end of their carousel.
Users need to upgrade to Pro for access to TH+ Frame Ratio, Series.

This $15 a year package comes with an entire treasure trove of other feature-rich tools, too, which include the capacity to upload and arrange more than two photographs or videos at a time, splitting content across more than three panels for Instagram's carousel or threads, high-definition export, the ability to export video up to sixty seconds long, the feature of previewing Instagram post or stories before exporting the files, and customizing templates so that you would save and use your desired look, the power of advanced tools for complex layout, or customize app icons.

Since the version 1.0 release in December 2019, Series has attracted approximately 5,000 monthly active users, half of whom pay for it. The app was upgraded to version 2.0 in December 2022 with video and additional layout options and has most recently added the TH+ Frame Ratio with a July release targeted toward Threads users.

The app caught the eye of Instagram head Adam Mosseri, who replied to a request from Series on Threads asking if there was a dev-relations person for Threads the app maker could speak to.
Working on tighter integration like faster workflow, better preview, more layout options, the post teased.
The app is free with in-app purchases on the App Store and supports both iPhone and iPad.
