## Description

Mix, measure, remember.<br><br>Tinct is a quiet calculator for fountain pen ink mixers — the kind of mixer who keeps a notebook, a syringe, and a small graveyard of jam jars on the desk. It does one thing: it remembers your recipes, exactly.<br><br>Add the inks you&#39;re combining. Tinct shows the ratios live as you tweak the drops. Slide to scale the recipe to any volume — 5 mL for a sample vial, 50 mL for a converter refill. Save it with a swatch photo and a line of notes about the paper and nib you tested.<br><br>That&#39;s it. No account. No cloud. No subscription. No ads.<br><br>KEY FEATURES<br><br>• Live ratio calculation with a visual colour bar<br>• Toggle between drops, grams, and millilitres<br>• Scale slider — 5 mL to 100 mL — with per-ingredient amounts<br>• Recipe library with swatch thumbnails and colour filters<br>• Notes field for paper, nib, conditions, observations<br>• Share a recipe as text — or export your whole library as a JSON file<br>• Local-only storage — your recipes never touch our servers<br><br>WHO IT&#39;S FOR<br><br>For the mixer who&#39;s been writing ratios on Post-it notes and losing them. For the FPN member who wants to share recipes the way good cocktail bars share cocktail cards. For anyone who has tried to scale &quot;5 drops Yama-budo, 2 drops Oxblood&quot; up to 50 mL and gotten the math slightly wrong.<br><br>PRIVACY &amp; BACKUP<br><br>Tinct stores everything on your device. No accounts, no servers, no analytics, no third parties — we never see your recipes.<br><br>• Export the whole library as a JSON file at any time — keep a copy wherever you trust it.<br>• Import the same JSON on another device to restore.<br><br>ABOUT<br><br>Tinct is an indie release inspired by a 2025 thread on the Fountain Pen Network asking for &quot;ink recipe software.&quot; This is that.
