## What is Hoparoma?

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. Cited in Settings → About.

## Version history (last 5 releases)

### 2.0.2 — 2026-07-02

This update makes Hoparoma's aroma readout more honest and easier to trust.

• Aroma compounds now show real concentrations alongside a clear perception level, with honest sensory-threshold ranges • Redesigned aroma bars that map concentration against perception zones at a glance • Haze-aware β-myrcene handling and a unified perception model (OAV, geometric-mean thresholds) • Recipe exports now match exactly what you see on screen • More reliable hop-variety picker when editing recipes • Cleaner Home screen layout

### 1.0.7 — 2026-06-09

Bigger hop library, sharper chemistry:

• 70 hop varieties (up from 51), with brewer-calibrated thiol data
• Beer color (SRM) and its color name now shown in every recipe's Vitals
• Dry-hop bitterness (humulinone) now factored into IBU
• Pick your hop form — T90 pellet, whole cone, Cryo, wet, or fresh — and enter the package α% for concentrated lots
• Reliability and BeerXML import fixes

### 1.0.4 — 2026-05-21

1.0.4 brings the Hoparoma narrative to completion — yeast, hop, malt, and Phantasm working together with a deeper data foundation and a calmer interface.

What's new:
• Thiol Suggestion engine — real-time recommendations for yeast and Phantasm changes to lift your tropical thiol score, presented inline on the result screen.
• Crop year-aware hop chemistry — 24 hop varieties × 3 crop years now factor into oil composition midpoint calculations and the aroma forecast.
• Yeast and malt depth — 21 yeast strains and 38 malt types unified to peer-reviewed literature with new biotransformation, availability, and thiol precursor badges.
• Refreshed home — atmospheric photo backdrop with thin glass action cards aligned with Apple's iOS 26 design language and HIG navigation-layer principles.
• Visual consistency — every screen migrated to the unified DesignTokens system for typography, spacing, color, and motion.
• Refined navigation — improved home / new-recipe confirm dialog when you have edits in progress.
• Subscription gating polish — suggestion engine Pro paths now correctly trigger the appropriate paywall.
• iPad layout — proportionally scaled home for iPad screen sizes.

### 1.0.3 — 2026-05-15

Introducing Thiol Forecast - the science of tropical aroma, made visible.

NEW IN 1.0.3:
- Thiol Forecast Bento card: a 3+1 layout score that predicts tropical thiol output from yeast × hop × malt, with Phantasm-style booster amplification
- 8 new yeasts: Helio Gazer, LalBrew New England, Lutra & Hornindal Kveik, A04 Barbarian (Conan), Belle Saison, WLP029 Kölsch, WLP077 Tropicale
- 11 new malts: Naked Oat Malt, CaraHell/Munich series, CaraAroma, Melanoidin, Abbey, Carafa, Aromatic
- Availability badges: know which yeasts/malts you can actually source (Mainstream / Limited / Pro Pitch Only)
- Thiol precursor metadata: every malt rated for thiol contribution (high / medium / low / negligible)

To our knowledge, the first brewing app to predict tropical thiol across all four ingredient layers. Built on peer-reviewed research from MDPI Fermentation, Springer EFR&T, and primary maltster/yeast lab specifications.

### 1.0.2 — 2026-05-09

Two new Mindful preset additions, plus biotransformation education features:

- Added Mindful Hazy Session IPA (4.3% ABV, NEIPA-style) and Sober-Curious Session Pale (3.8% ABV, Galaxy and Nelson Sauvin). Phantasm thiol boost preserves tropical and citrus aroma even at lower ABV.
- Annotated all 5 existing presets with recommended yeast biotransformation level (High, Medium, Low).
- Yeast picker now shows beta-lyase activity badge. When Phantasm is dosed with a low-biotransformation strain, a non-blocking warning highlights the mismatch.
- Hop stage selection now displays biotransformation context (Whirlpool, Active fermentation DH, Post-fermentation DH).
- Phantasm slider range tuned per preset (Mindful 0.5 to 2.5 g/L, SMASH 0 to 12 g/L, others 0 to 10 g/L).
- Recalibrated the 7-axis aroma radar against 25 plus peer-reviewed sources for sharper varietal expression.

Existing recipes will display under the recalibrated model. Enjoy exploring the Mindful narrative and designing low-ABV beers without losing aroma.
