Brevo.

Brevo is your private home baking calibration studio. Log oven temperature offset tables for baking recipes, track material spending habits, save a journal diary, and chart weekly balance trends — all on your device with no account, no cloud, and no feed.

Oven offset tables

Register each recipe, enter target bake temperature, oven dial setting, and optional probe readings. Brevo computes your offset live and builds a multi-row calibration table you can revisit before every bake. Save to update the recipe chip badge instantly.

Material spending

Log spend slips with merchant, amount, and category chips. HeatPulse turns your week into a donut breakdown so you see where flour, dairy, and tools actually go.

Bake journal

Write reflective entries with mood tags, finished-bake photos, and spoken notes — separate from structured offset logs.

Weekly balance trends

The HeatPulse dashboard shows today's snapshot counts and a donut chart with tap-through category detail. Export a weekly summary card to your photo library when you want a shareable snapshot.

History archive

CrumbArchive lists every offset table, spend slip, and journal entry in one chronological feed with searchable filters and full detail pages.

Privacy and data

All data stays on your iPhone. Photos and recordings are stored in the app sandbox using relative paths. No tracking, no server sync.

In-app purchases

Crumb Coins are optional consumable credits for extra recipes, saves, and chart exports after free monthly quotas. Purchases are handled securely through the App Store.
