A product that has reached #1 on the front page of Hacker News and topped the paid tools chart across all European countries, while ranking #2 in the US on the same day. Queryable is an open-source, offline photo album search tool unlike anything you've used before. Search your photos with natural descriptions like "two people by the sea," "a blonde woman holding a glass of red wine," "a girl in red on the lawn," or even emotional moments like "We fell in love." Queryable understands longer, more human descriptions instead of only simple tags. You can type in your own language: non-English queries are translated on your device before searching. NEW: SEARCH THE TEXT IN YOUR PHOTOS Turn on text recognition and Queryable also finds photos by the words in them: a Wi-Fi password in a screenshot, the total on a receipt, a dish on a menu, a line on a lecture slide. Switch between Visual and Text search with one tap, and copy all the text from any photo. Recognition uses Apple's on-device engine at its highest accuracy. It is off by default, so building your index stays as fast as before. ALSO IN QUERYABLE • Search by photo: pick or take a photo to find similar ones • Clean up duplicates and similar shots group by group, with space estimates • Filter results by date, select in bulk, and share full-resolution originals • Videos and Live Photos play with sound, even in silent mode; GIFs animate • A redesigned interface with your recent searches one tap away Pay once and use it forever. No ads, no subscription. Queryable works completely offline after download, protecting the privacy of your photo library. FAQ: 1. What languages can I search in? You can describe photos in your own language. Queryable translates your query on device, while keeping the accuracy of the English search model. The first time, iOS asks once to download your language for offline translation; you can also do it anytime in Settings. Text search looks for the words exactly as they appear in your photos; it reads English and, where Apple's engine supports it, your device language. The app interface is available in 18 languages. 2. How is my photo privacy protected? Queryable works completely offline. You can even disable the app's network permissions. The only time it uses the network is when you choose to download the full-resolution original of a photo stored in iCloud. 3. How do I use it? After downloading, build an index for your photos. This takes a few minutes depending on your library and device, and is only required once. When you add new photos, you can update the index at any time. Text recognition is optional and slower than the visual index; you can pause it and continue later. 4. Why can't Text search find some photos? With "Optimize iPhone Storage" turned on, many photos are kept on your iPhone only as small previews that are too small to read. Open such a photo and download the original, and its text is recognized automatically. Contact: - Email: myfancoo@gmail.com - Twitter: @immazzystar - GitHub: https://github.com/mazzzystar/Queryable
Metamer
Read full descriptionHide full description
Metamer points your camera at the world and shows it through different color vision. Live simulation of protanopia, deuteranopia, tritanopia, and achromatopsia lets people with typical color vision experience what friends, family, and audiences see. Daltonize filters do the inverse: they boost color separation so people with color vision deficiency can tell confusing colors apart. —— LIVE COLOR VISION CAMERA —— Pick from seven simulation and daltonize filters and watch the world change in real time. A severity slider tunes every filter for color weakness, and each filter remembers its own last setting. Flashlight, front/back flip, and a zoom control that speaks the same 0.5x / 1x / telephoto language as the system Camera. —— TRUE COLOR NAMING —— A movable reticle names the real color under it, even while a filter is active: a carefully chosen palette of everyday names, the measured swatch, and the exact hex value. Freeze the frame to inspect a moment, move the points, and switch filters on the held still. Add a second point to compare two colors and get a plain-language verdict on how different they really look. —— FILTER YOUR PHOTOS —— Pick any photo and compare original and filtered side by side with synced zoom and pan. Tune the filter strength, then share the result as JPEG or HEIC with full metadata preserved. —— ISHIHARA PLATE GENERATOR —— Build custom color vision test plates: digits, short text, or arrows, with confusion-line colors for each CVD type and adjustable difficulty. Export print-grade PNG or PDF at 300 DPI. —— KNOW YOUR TYPE —— An optional quick check at first launch suggests a starting filter, with graded follow-up plates that estimate how strong it should be. Already know your type? Skip straight to it. It is a quick check, not a medical diagnosis. —— ACCESSIBLE & PRIVATE —— Every screen works with VoiceOver, including an optional spoken color readout. Everything runs on your device: no images ever leave it, no accounts, no tracking, no data collection. Metamer is for designers checking their work, teachers and presenters building accessible materials, families understanding how a loved one sees, and anyone with color vision deficiency who wants colors named and separated.

Verdict
The clearest difference is price: Metamer at Free against Queryable's $4.99. Queryable's advantage is update cadence (every 2 weeks vs every 4 months) and chart position (#57 vs unranked). On ads, in-app purchases, device support and iOS requirement there is nothing between them.
