The product exists, is live on the App Store, and is positioned exactly around the screenshot/bookmark problem described in the post. Apple metadata for app id6758998468 lists the app as "Stash Anything: Save For Later" by Sean-Thomas Hammon, in the Productivity category, priced Free, with a public releaseDate of 2026-02-26T08:00:00Z and currentVersionReleaseDate of 2026-05-09T18:07:01Z. The same metadata says the app is for iOS 18.0+, which implies this is a recent launch built against current Apple platform APIs rather than an older recycled app.
Apple's own description matches the original framing almost line-for-line. It calls Stash "your bookmark manager and read-later app for everything you don't want to lose" and says users can "Save links, photos, screenshots, videos, GIFs, recipes, social posts, product pages, places, PDFs, tweets, articles, and quick notes" in "one clean, searchable home that syncs across iPhone, iPad, and Mac." It also explains the workflow in a simple six-step flow beginning with "Tap Share in any app or browser" and "Select Stash in the iOS Share Sheet."

A second official-site snippet reinforces the same positioning from the marketing side: "Stop losing links, TikToks, and screenshots in your camera roll. Stash is the private, offline-first app to save and organise your digital life in two taps." Another snippet on the main site describes shared folders: "Share stashes with friends and family to save things together in one folder. Perfect for planning weddings, organising group trips, or brainstorming work ideas." Those lines matter because they show the product is not just a screenshot cleaner; it is being sold as a broader save-anything layer on top of the iPhone share sheet.

The strongest public traction signal is App Store ratings rather than installs. Apple's lookup endpoint showed averageUserRating: 4.51724 across userRatingCount: 29 at the time of retrieval. For a product released on 2026-02-26, that is a credible sign of real early engagement for a niche productivity app, especially one that solves a concrete daily annoyance rather than chasing a broad social audience.

The developer page also shows Sean-Thomas Hammon has shipped multiple apps, not just this one. Apple lists Stash Anything, 3act: Accountability & Goals, and Boinky under the same developer account. That does not prove Stash's growth, but it does suggest the maker is not a first-time App Store publisher and likely had some prior distribution or product experience.

The app's Instagram profile was lightweight when fetched: 6 followers, 0 following, 24 posts. That is useful because it implies the product was not riding a large existing social audience. If the app is genuinely becoming the maker's and his wife's "most opened app," that usage pattern is probably being driven by utility and habit formation rather than influencer-scale marketing.

The original Reddit story claims: "My wife and I had 40,000 screenshots between us" and "One month on, it's the most opened app on both our phones and has 3000+ downloads." Public search snippets from Reddit and related reposts preserve those lines, and another snippet says: "So I built Stash. Two taps in the Share Sheet, pick a folder, done. Screenshots don't dump in your camera roll. That's the whole app." Source URLs: https://www.reddit.com/r/SideProject/comments/1t6dpei/my_wife_and_i_had_40000_screenshots_between_us_i/, https://www.reddit.com/r/AppBusiness/comments/1ta2bxr/i_hated_having_screenshots_in_my_camera_roll_so_i/, and https://www.reddit.com/r/IMadeThis/comments/1t6d9h8/i_made_a_tool_that_means_you_can_actually_find/
However, those Reddit pages blocked direct fetches from this environment, so the exact post body could only be recovered through search-result snippets, not full-page scraping. More importantly, the 3,000+ downloads claim is not supported by the strongest public third-party number I found. MWM's app intelligence page describes the app as "rated 4.2/5 with < 1k downloads" and another search snippet exposes the page's market summary as "Current rank 30+ Outside top 30 · US Free · Productivity · Downloads · < 1k." Source URLs: https://mwm.ai/apps/stash-anything-save-sort/6758998468 and the corresponding search snippet returned for that URL.
That does not necessarily make the Reddit claim false. MWM may lag, estimate poorly, or undercount installs, and Apple does not publish install totals on the public App Store listing. But on the available public evidence, the safest conclusion is: the app launch and product-market fit story are real; the precise 3,000+ download figure remains a self-reported claim rather than a publicly verified metric.
This looks like a good example of a founder noticing a high-frequency personal behavior, then reducing it to an extremely low-friction workflow: save from the iPhone share sheet, file into a stash, search later. The compelling part is not technical novelty; it is how aggressively the app narrows in on a habitual user problem. The public record supports the app's existence, recent launch cadence, positive early ratings, cross-device sync story, and organic-feeling positioning around screenshot overload. What it does not fully support is the headline install number. For a research summary, I would treat 40,000 screenshots, most opened app, and 3,000+ downloads as founder claims, while treating the App Store metadata, ratings, release date, and official product copy as verified facts.
