What Is the Retro App? How It Works, Makes Money and Grew

Retro is a private photo journal for friends. Once a week (or daily or monthly, if you prefer), you post photos and videos from your camera roll, and only friends you approve can see them. Your friend list and likes are private, and you have to post to see what your friends posted. Nathan Sharp and Ryan Olson, who worked together on the launch of Instagram Stories, released it on iOS on July 13, 2023. It had roughly a million users in December 2025 and around 7 million downloads by August 2026, according to Appfigures data cited by TechCrunch.

Retro makes money from subscriptions, not ads. Retro Premium costs $4.99 a month or $35.99 a year on the US App Store and adds video, GIF and sticker comments, more styles, unlimited history and extra app icons, according to TechCrunch. Retro does not publish revenue. It raised $21.1 million in a round that closed December 31, 2025 (SEC Form D). TechCrunch reports it as a Series A led by Field Ventures and Thrive Capital.

Every figure about Retro in this case study comes from a public source: its app store listings and website, its SEC filing, Apple and Snap announcements, and press interviews with the founders. We read Retro's TikTok, Instagram and X profiles on October 2, 2026, and counted the views on every TikTok video they show.

How does the Retro app work?

Retro works like a weekly photo dump that only your friends can see. Engadget's August 2026 walkthrough and the App Store listing describe five rules:

1. You choose a rhythm. At setup you pick daily, weekly or monthly, and Retro nudges you to post on that schedule.
2. You post from your camera roll. Each week fills with photos and videos you already took. On the free plan, the picker only shows photos from the current week.
3. You post to see. You have to post at least once a week to see what your friends posted (Premium skips this rule, per Engadget).
4. Friends see recent weeks, keys open the rest. Friends see your last four weeks. To let someone scroll your whole journal, you give them a "key" (TechCrunch, July 2023). Premium lets you hand out as many keys as you like.
5. Nothing is public. Your friend list and the likes on your posts are private, and captions are optional.

Around that core, Retro has added group albums you can share with a link in a group chat, recaps (a collage or video slideshow of your week, month or year that you can post to Instagram), printed postcards mailed via USPS, group chats and home screen widgets. In December 2025 it added Rewind, a dial for scrolling back through your camera roll and sharing old photos with friends.

Is Retro like BeReal?

Partly. Both are for friends only, and both make you post before you can look. The difference is timing: BeReal picks the moment for you, Retro gives you the week.

How does Retro make money?

Retro sells a subscription and shows no ads. The US App Store listing lists five Premium options, and Google Play shows the same range of $1.99 to $35.99 per item.

Feature lists come from TechCrunch and Engadget. Engadget also reports a referral offer that doubles as a growth tactic: invite five friends who join and you get a year of Premium; invite ten and you get a lifetime pass.

Revenue is not public. On its Form D, Retro chose "Decline to Disclose" for revenue. The only public sign of how sales are going is Appfigures data cited by TechCrunch: in-app spending rose by more than 460% over the 180 days before August 28, 2026. PitchBook estimates the company's valuation at over $100 million.

The no-ads choice is deliberate. Retro's ethos page says that "Retro must become a profitable business", but separates that from "optimizing every pixel in your app for a business outcome". In 2024, Sharp told TechCrunch: "We don't sell or rent our user data to anybody."

How did Retro grow?

Retro's public numbers are sparse until late 2025, when it reached the top of the charts in Europe. In December 2023, Sharp said half of the people who opened Retro on a given day also posted. By December 2025 it had about a million users, and Fast Company reported it was the number one photo app in 12 countries and the number one app overall in six: Germany, Austria, Finland, the Netherlands, Sweden and Switzerland.

   2022: Lone Palm Labs is founded

   Sharp spent over six years at Meta on products including Instagram Stories and Facebook Dating, per TechCrunch. Olson was Instagram's iOS tech lead and later its director of engineering until May 2022, per TechCrunch. The company was incorporated in Delaware in 2022, per its Form D.

8. 8

   December 2025: Rewind and the top of the charts

   Retro launches Rewind with about 1M users and 45.7% of them active daily. Fast Company reports number one overall in six European countries. Retro's German TikTok account gets 4.5M views that month, almost all on videos about moving Snapchat Memories into Retro, none of the biggest ad-flagged.

9. 9

   December 31, 2025: the round closes

   $21,104,978 sold to 7 investors, out of $21,999,978 offered. The first sale was on October 17, 2025.

10. 10

    August 2026: the round becomes public

    Retro files its Form D on August 19. TechCrunch reports it on August 28, with about 7M downloads, in-app spending up 460% in 180 days and a PitchBook valuation estimate above $100M.

What drove the late-2025 jump? Three things landed within three months: Snapchat's storage cap, the Apple award nomination and the Rewind launch. Retro's German TikTok turned the Snapchat cap into its biggest month, with how-tos for moving Memories into Retro, and in December Retro reached number one overall in Germany. What the founders have said about marketing is older: in May 2024 they told the Apptisan newsletter that they had marketed Retro through "word-of-mouth, a little press, and the photos that people share outside of Retro as recaps on Instagram or as photo postcards in the mail."

What did Retro post on TikTok?

A handful of videos carried Retro's TikTok, and most of them carry TikTok's ad flag: the isAd field in each video's public page data. It is set on every main-account video above 300,000 views and on the German account's three biggest. It is not set on the German account's December videos about Snapchat.

The main account: 8 ad-flagged videos brought 88% of the views

@retrodotapp, the account Retro's App Store listing points to, had 12,008 followers and 213 videos on October 2, 2026. The videos had 8.7 million views, but the median video had 1,636. The eight videos above 300,000 views, all ad-flagged, account for 7.6 million. The other 205 got 1.07 million between them.

July 2024: five promoted videos. Five of the six July videos passed 500,000 views, and all five carry the ad flag. The sixth, without it, got 1,055. August to November 2024: volume. The account posted 174 videos, many in the first person as a college student, with a median of 1,280 views. These first-person videos on the brand's own account follow the Canvas UGC format. Only 9 passed 10,000, and the three biggest are ad-flagged. The biggest of all, posted August 26, 2024, has 2.8 million views, the caption "Make your august recap now" and the on-screen line "my new fav app to store memories without making my phone run out of storage".

The main account has posted once since August 2025, on October 1, 2025. In the same period, Retro's local-language accounts took over.

The local accounts: Snapchat how-tos, then ads

Since late 2025, Retro-branded accounts in German, Spanish and Japanese have posted alongside the main account, and all of them tag it in their captions.

The German account has 2.2 times the main account's views with fewer followers. Two bursts brought 98% of them:

December 2025: Snapchat Memories, no ad flag. Eleven weeks after Snap announced its storage cap, the German account posted 21 videos whose captions mention Snapchat, many of them how-tos for moving Snapchat Memories into Retro. They got 4.47 million views, 98% of the month's total. Six, posted December 11 to 15, got 344,000 to 1.3 million views each, and none of the seven biggest carry the ad flag. The 1.3 million-view video opens with the line "Snapchat kostet jetzt" ("Snapchat costs money now"). That month Retro reached number one overall in Germany.

May 2026: "How to: Bester Sommer", ad-flagged. Three videos set to the same sound, two titled "How to: Bester Sommer" (best summer), got 4.3 million, 3.0 million and 6.6 million views on May 7 and May 17. All three carry the ad flag. The account's other 302 videos got about 5 million views between them.

Spain shows the same split. Retro España's biggest video, at 421,000 views, carries the ad flag. Its second, at 210,800 views without one, is captioned "los recaps de retro".

Where is Retro most popular?

Retro is a US company, but most of its App Store ratings come from outside the US. Across the 26 App Store storefronts we checked on October 2, 2026, Retro had 61,420 ratings, and 74% of them came from outside the US. Japan alone has 13,401, nearly as many as the US, and Germany, Austria and Switzerland together have 9,568.

On Android, Google Play shows more than 1 million downloads and a 4.8 rating from 19,300 reviews. The Android app was released on December 6, 2023.

What app teams can learn from Retro

Make the product's output the ad. Retro's founders said they marketed the app through things users make and share outside it: recaps on Instagram, postcards in the mail, and album links that work without an account. Its best TikToks without the ad flag do the same: the Spanish account's biggest is about recaps, and the German account's December peak was how-tos for moving Snapchat Memories into the app.

Separate paid from organic before you copy a video. Every main-account video above 300,000 views carries TikTok's ad flag. Copying the July 2024 format because it looked viral means copying ad spend. Check whether a video was promoted, then compare its organic views with your account's median, as we explain in how many views is viral.

Answer the question people have this week. The German account's biggest unpromoted month came from Snapchat's decision to charge for Memories storage: a how-to in German with the hook "Snapchat costs money now". Storage was Retro's angle twice; its most viewed main-account video, in August 2024, pitched saving phone storage too.

Expect a few videos to carry the account. The top three videos brought 54% of the views on the main account, 74% on the German one and 84% on the Spanish one, against 35% for the median of about 4,500 TikTok accounts tracked in viral.app with 100 to 400 posts. Across 1.4 million TikToks from accounts tracked in viral.app, about 1 in 20 got 10 times its account's median. The sub-$1 CPM UGC playbook shows how apps plan for those odds.

Count installs, not views. None of Retro's public numbers link a video to downloads. Cluely's founder wrote in September 2025 that one UGC video got 49 million views and fewer than 100 downloads, a story we cover in how Cluely went viral.

How we gathered the numbers

• Company facts come from Retro's SEC Form D (filed August 19, 2026), its App Store and Google Play listings, its ethos page, Apple's and Snap's newsrooms, and articles in TechCrunch, Fast Company, Engadget and the Apptisan newsletter, linked where each figure appears.
• App Store ratings, ranks and the iOS release date were read on October 2, 2026, from Apple's public lookup for 26 storefronts and from each country's App Store page.
• TikTok numbers were read logged out on October 2, 2026. We loaded every video on each profile and recorded the view count TikTok shows on the grid. TikTok rounds large counts, so totals are approximate. Post dates come from the video IDs and are in UTC.
• Ad flags come from the isAd field in each video page's public data. We checked 27 videos: the 9 most viewed on the main account plus 5 smaller ones, the 10 most viewed on the German account and the 3 most viewed on the Spanish one. Videos we didn't check are counted as "other" in the charts.
• Benchmarks come from 1.4 million TikTok videos posted between October 1, 2025 and August 31, 2026 by about 21,000 accounts tracked in viral.app, each with at least 10 videos, and from about 4,500 tracked accounts with 100 to 400 posts (videos and photo posts) in the same period.
