What it does

Everything below is shipped and working today — nothing aspirational. Weather, the logbook and the community are free. The risk engine is Premium.

The risk engine

Premium

Ten diseases and pests, each with its own published model. It produces dated infection events with deadlines — never a score out of 100.

Ten threats modelled: downy mildew, powdery mildew, botrytis, black rot, phomopsis, anthracnose, sour rot, grape moth (four species, selected by geography), Pierce's disease and trunk disease.
Infection events, not scores. Published epidemiological models — temperature × leaf-wetness response surfaces — produce dated, checkable events, each written as one sentence with a deadline.
Biogeography: pests that don't occur at your location are not assessed — and the app says so, and says why. "Not present here" is never shown as "no risk".
Phenology, not calendar: growth stage from degree-day accumulation on the BBCH scale, season phase from phenology — so both hemispheres work, and every timestamp is read in the vineyard's own time zone.
Site adjustment: elevation, slope, aspect, cold-air drainage and soil drying all modify the assessment.
A treated risk doesn't vanish — it shows as "mitigated — protected until Friday". The risk stayed real; your action is what changed.
One engine, shared: the identical code runs in the app and on the server that sends pushes, so a notification can never disagree with the screen.

Free

All weather is free: hourly and daily forecast, seven days of history and all eight alert types — at your vineyard's exact coordinates.

Hourly and daily forecast plus a 7-day history, at the vineyard's coordinates — not a regional average.
Eight alert types: heavy rain, extreme heat, frost, strong wind, rapid temperature drop, hail, drought stress and high humidity.
Frost with real severity levels — FAO critical-temperature tables by tissue and growth stage — with the radiative vs advective distinction, a dew-point gate and cold-air drainage.
Spray windows: hour-by-hour suitability over the next 48 hours from delta-T, wind, temperature and rain — with the reason named when no hour is suitable.
The weather-to-risk analysis — which factors are driving each disease — is the one weather surface that is Premium.

Free

Logging is central, not a side feature — and the legal spray record it produces is free, whatever your subscription.

Every protective treatment names the disease or diseases it targets — mandatory — and mitigates only those.
Protection tracked per block: protected / expiring / expired, decaying by product class, washed off by rain. Cover lapsing before the next risk is itself an alert.
A full compliance record per spray: EPPO codes, BBCH stage, authorisation number, active substances, dose, area, pre-harvest interval, re-entry interval, wind at application, applicator identity and justification.
Per-record validation with honest "Missing: …" lines. The pre-harvest interval computes the earliest legal harvest date and blocks harvest with a countdown.
Export as CSV, XML and the Portuguese Caderno de Campo Único layout. PDF and JPEG are deliberately refused — not machine-readable under Reg. (EU) 2023/564 — and the app says why.
Records stay accessible whatever the subscription state.

Half the year happens when every competitor goes quiet. SOSVine works in January.

Pruning readiness per block — chill satisfied? rain within 48 hours? — with go / take-care / blocked verdicts and a one-tap "block pruned".
Wound protection: cut susceptibility decays on a published healing curve, and the app alerts when rain is forecast onto open wounds.
Winter chill in Dynamic Model chill portions, measured against the requirement of the varieties actually planted.
Season review (Premium): infections that occurred, sprays versus advised intervals, resistance-group rotation with repeated substances flagged, and "what to do differently" — the November artefact a grower shows their consultant.

Free

What your neighbours confirm in their rows feeds the model that watches yours.

Report sightings with severity and photo; browse a list and a clustered map of nearby reports.
Anonymous, with a 14-day expiry and early close.
Nearby confirmed reports feed the risk model — the network effect.

A push marks a change, not a state. If SOSVine is loud, something changed.

Episode-based alerts: one push per day, then a digest. Escalations always get through; critical pierces the budget; quiet hours are honoured.
An optional daily report at the hour you choose (Premium).

Wherever grapes grow.

Six languages — English, Portuguese, Spanish, French, Italian, German — with metric and imperial units.
Around 60 wine countries with localised names, both hemispheres, every timestamp in the vineyard's own time zone.
iOS and Android.
