From intent to evidence
Bench control, end to end
Buffercast separates planning estimates from measured results. Every batch keeps its formulation revision, source lots, ordered additions, observations, calibration chain, and accountable disposition together.




Built for technical work
Useful controls, visible limits
No hidden recommendation engine and no automatic acceptance. Buffercast calculates from the values you enter and keeps the method boundary visible.
Target volume, pH, tolerance, temperature, component order, stock strength, reagent form, source lot, and a deterministic SHA-256 fingerprint.
Stock transfer, solid mass, percent formulations, and an idealized conjugate-pair estimate with range and temperature warnings.
Run identity, operator, controlled checklist, planned versus actual quantities, deviations, pH observations, and notes.
Measured pH, temperature, conductivity, osmolality, instrument IDs, calibration references, reviewer, rationale, and disposition.
Export a batch PDF, additions CSV, pH-observation CSV, and structured JSON evidence packet through the iOS share sheet.
No account, analytics, advertising, tracking, cloud database, camera, microphone, location, contacts, or photo-library permission.
Primary references
Methods should be inspectable
Buffercast links to primary metrology and laboratory-safety sources. User-entered values and planning equations do not replace validated procedures, certified references, safety documentation, or professional judgment.
