Fermento - Professional Fermentation Timer & Tracker

Master the art of fermentation with Fermento, the comprehensive tracking app designed for home fermentation enthusiasts. Whether you're brewing kombucha, fermenting kimchi, making tepache, or creating custom ferments, Fermento provides the precision timing and tracking tools you need.

KEY FEATURES

Multi-Phase Timers
Track ferments through primary, secondary, and custom phases with individual countdown timers. Each phase has its own dedicated timer showing days, hours, and minutes remaining with beautiful circular progress displays.

pH Tracking
Optional pH monitoring for each phase ensures perfect fermentation conditions. Record pH readings as you advance through phases and review them in your brew history for future reference and recipe refinement.

Preset Brew Types
Start quickly with expert-optimized presets for:
• Kombucha (7-30 days with F1 and F2 phases)
• Tepache (2-5 days traditional pineapple ferment)
• Kvas (2-3 days bread-based beverage)
• Kimchi (3-21 days vegetable fermentation)

Custom Recipes
Create your own fermentation recipes with unlimited custom phases. Define phase names, durations, colors, and icons. Your custom brew types are saved permanently for future batches.

Multiple Simultaneous Brews
Track one ferment at a time for free, or as many as you like with Fermento+. Each timer is independent with its own:
• Custom label for easy identification
• Current phase and progress
• Real-time countdown display
• Individual pH tracking
• Separate phase history

Comprehensive Brew History
Complete record of all finished ferments including:
• Total fermentation duration
• All phase details and durations
• pH readings for each phase
• Start and end dates
• Brew type and custom labels

Backdate Start Times
Start tracking existing ferments by backdating the start time. Perfect for adding ferments that are already in progress.

Auto-Save & Backup
Automatic backups every 60 seconds ensure you never lose your fermentation data. All saves happen locally and automatically—no manual saving required.

PRIVACY & SECURITY

Fermento is built with privacy as the foundation. Your ferments are stored locally on your device with:
• No accounts, ever
• No tracking, analytics or ads
• No name, email or location collected
• Works offline
• On-device AI — your questions never leave your phone

Your fermentation data never leaves your device. Roadmap votes and article likes are anonymous: each one carries the item you picked plus an app-scoped device id, used only to keep a vote or a like to one per install. Nothing else is sent, and nothing identifies you.
