About this app

S.D Timer calculates your sourdough starter feeding schedule based on target bake time and ambient temperature.

Enter your starter weight, desired hydration, and target bake time. The app computes precise feeding intervals and exact gram measurements for flour and water to keep your starter at peak activity when you need it.

Key features:
- Temperature-aware timing: feed intervals adjust to ambient temperature (fermentation rate scales with temperature per Arrhenius kinetics)
- Gram-precise flour and water quantities per feeding
- Fermentation timeline with phase markers
- Baker's notes for tracking observations
- Fully offline — no account or internet required

Built for professional bakers and serious home bakers who need reproducible, data-driven schedules instead of approximations.

Note: Free version supported by ads.
