Hoparoma - IPA Hop Recipes

As far as I know, Hoparoma is the first iOS app to predict tropical thiol — the science behind every juicy, modern IPA — across yeast, hop, malt, and Phantasm. Most brewing apps tell you what hops to use. Hoparoma predicts what your beer will smell like, before you brew it. Version 2.0 rebuilds the whole app around that idea. —— SEE YOUR AROMA AS A FINGERPRINT —— The 2.0 result screen reads your recipe's aroma as a fingerprint on one page: a 7-axis profile (Citrus, Tropical, Floral, Herbal, Spicy, Resin/Pine, Dank/Earthy) plus a Thiol Forecast in a composite hero, with a color computed per recipe. Contributions break out by stage — Boil / Whirlpool / Dry Hop / Cold Dry Hop. —— THREE-TAB WORKFLOW —— Home, Lab, and Journal — a clean design → brew → log flow. —— A PREDICTION ENGINE BACKED BY LITERATURE —— Built on Stevens power laws from Lafontaine & Shellhammer (2018). Dry-hop saturation, contact-time decay, and over-hopping are modeled explicitly — including the citrus/floral plateau at high dose rates. Every coefficient is auditable in-app, and the engine's limits are disclosed honestly. —— LIBRARIES —— HOPS (70 varieties): brewer-calibrated thiol data, plus lot-level crop-year alpha and oil for 2024–2026. YEAST (29 strains): each rated for thiol biotransformation activity, with sourcing badges (Mainstream / Limited / Pro Pitch Only). MALT (41 entries): each rated for thiol precursor level. Beer color (SRM) is predicted from your grain bill on every recipe. —— BREWING JOURNAL —— Save a recipe, brew it, then add a photo tasting log. Hoparoma shows the predicted-vs-perceived gap on each axis; save it as a named Personal Correction and apply it to similar recipes to overlay your own taste. —— IMPORT FROM BREWFATHER & BEERSMITH (PRO) —— BeerXML import reads standard .beerxml / .xml files and maps your hops, yeast, and malts to the chemistry model — a Thiol Forecast on every imported recipe. —— MINDFUL RECIPE PRESETS —— Mindful Hazy Session IPA (4.2% ABV) and Sober-Curious Session Pale (3.8% ABV) keep tropical aroma at low ABV — plus 4 classic hop-forward presets. —— BONUS ON SUPPORTED DEVICES (APPLE INTELLIGENCE) —— On Apple Intelligence devices: an AI brewing co-pilot (describe a goal, get engine-checked suggestions, 5 free tries) and a Flavor Forecast from your numeric profile. On other devices these point you to supported hardware, and every other feature still works. —— PRICING —— FREE: Core Thiol Forecast, basic recipe management, up to 2 saved recipes PRO MONTHLY: $5.99/mo — unlimited recipes, advanced thiol modeling, full Mindful presets PRO ANNUAL: $39.99/yr (7-day free trial, then $39.99/year billed automatically until cancelled) LIFETIME: $69.99 (limited launch edition) — own Hoparoma forever, support indie development Subscriptions auto-renew at the end of each period unless cancelled at least 24 hours before the period ends. Manage or cancel anytime in Apple ID settings. Lifetime is a one-time purchase, not a subscription. —— WHY HOPAROMA —— Brewfather optimizes recipe management; BeerSmith adds hop-side thiol awareness. Hoparoma models thiol biotransformation across every layer — yeast β-lyase, malt precursors, hop thiols, and Phantasm dose — in real time as you build. For anyone trading guesswork for chemistry. —— SOURCES —— Predictions are built on peer-reviewed research (Chenot et al. 2019–2023; Roland et al. 2016, 2018; Hellwig et al. 2022; Molitor et al. 2022) and public manufacturer specs.
