What's New in Loupewise
2.3.19
October 23, 2026
New - Goal chooser on first launch: people say what they came for (identify a stone, or exam prep) and the app starts there. Your new customer picked "exam prep". - Free CSV export of any collection, on every tier. It round-trips through Import. - Test Treatments works for all 132 gems. It used to be unreachable for most stones (D11). - A new landing screen (in all 15 languages) with a plain trust line: no camera, no machine learning. - More of the app in 14 languages: the identify screen's 20 instrument hints, the trial button, the Pro tier list and the walkthrough prompts. Fixed - The paywall no longer closes the screens underneath it after a purchase. This is today's fix. - The Hobbyist plan subtitle no longer claims "Unlimited". - Spectroscope labels print as Fe/Mn/Cr instead of FE/MN/CR. - Cat's-eye chrysoberyl: reporting "no milk-and-honey effect" no longer wrongly rules it out. Data corrections, each with a source: - Synthetic spinel was showing natural spinel's refractive index. - Opaque hematite was listed with facet doubling a loupe can see. - 17 "0.000" dispersion values were placeholders published as measurements, and are now blank. - Benitoite (heatable), synthetic spinel (quench-crackled) and hauyne (waxed) were wrongly labelled untreated. - About 20 "untreated" labels now say exactly what their source supports. - 13 simulant ranges now match the rows they name.
