Roast Window
A subscription and freshness tracker for green-coffee buyers that times your roasts so beans land in their optimal 'rest' window before you brew, with shipping delay buffers and AI suggestions based on your local climate.
Home coffee roasters buying green beans in 5-25 lb bags
- Optimal rest-window countdown for each batch (roast date + bean profile)
- Shipping-delay buffer so an Amazon delay does not ruin your plan
- AI 'brew-by' deadline that nudges you before a bag goes stale
- Side-by-side roast log with cupping notes so you can compare profiles
Specialty home roasting is booming and most roasters still manage rest windows in spreadsheets, even though small timing shifts visibly change cup quality.
Home coffee roasters market is real and growing — $1.2B in 2024 with 7.5–8.5% CAGR to ~$2.3B by 2033, and several indie apps (Roast Buddy, Roasted Beans, Roastmark, RoastSherpa) have launched in recent years validating the enthusiast base; however the specific 'rest window optimization' need is a niche sub-feature rather than a stand-alone pain point.Home Coffee Roasters Market Size, Trends, Insights 2034 ↗Roasted Beans — Home Coffee Roasting Companion App ↗
Multiple free competitor apps already cover green bean inventory, roast logging and cupping (Roasted Beans explicitly tracks origin/process/supplier/weight), but none I found combine subscription tracking + rest-window timing + shipping-delay buffers + climate-based AI; the specific combo is unclaimed but the adjacent space is crowded with free tools.Roasted Beans — Home Coffee Roasting Companion App ↗Roast Buddy — The coffee roasting app for the rest of us ↗
Home roasting is a notoriously frugal hobby — Roastmark is free, Roasted Beans is free at signup, Roast Buddy offers free logging with paid AI coaching, and Cropster (the commercial reference) prices by roast volume; a paid subscription for a narrow timing tool against multiple free alternatives suggests below-average willingness to pay.Roastmark — Coffee Roast Tracking App for Home Roasters ↗Cropster Pricing ↗
Specialty/home coffee is a structurally growing category — specialty coffee market projected $24.8B → $61B (10.5% CAGR) and home roaster hardware market 7.5–8.5% CAGR, indicating durable multi-year demand for tooling in this niche.Global Specialty Coffee Market Size, Trends, Share 2033 ↗Home Coffee Roasters Market Report [2032] ↗
Core is standard CRUD + carrier API + weather API + notification scheduling — all well-trodden territory — but the 'AI suggestions based on local climate' claim is weak because per-user datasets are tiny and bean-aging-by-climate is not a validated model, requiring careful scope.Roasted Beans — Home Coffee Roasting Companion ↗
