LSI Calc DB Water Balance Log

Track LSI readings faster with instant calculations, saved site profiles, sortable records, spreadsheet browsing, and CSV/JSON export built for pool service routines.

LSI Calc DB Water Balance Log is built for pool and spa professionals who need fast, repeatable water chemistry checks without jumping between paper logs, spreadsheets, and separate calculator tools.

Use the app to calculate Langelier Saturation Index (LSI), save readings by site, monitor chemistry trends over time, and export clean records when clients or supervisors ask for proof of service. Everything is organized for real route work: quick data entry, easy edits, and clear readouts.

Why teams use LSI Calc DB:

• Built around LSI workflow, not generic note taking.
• Designed for recurring site visits and repeat measurements.
• Fast enough for field use, structured enough for reporting.
• Works for both quick checks and long-term record history.

Core calculator and record features:

• Calculate LSI from TDS, water temperature, calcium hardness, total alkalinity, and measured pH.
• Switch between Fahrenheit and Celsius inputs.
• Get instant LSI category feedback from scale-forming to corrosive ranges.
• Save measurements as records tied to a site name.
• Keep record notes for service details, observations, or treatment context.
• Update existing records after retesting water on-site.
• Duplicate prior records to speed up repeated service calls.
• Search records by site, date, and notes.
• Sort record history by date to review newest or oldest trends quickly.

Site management and operational flow:

• Create reusable site profiles in Add Site.
• Store simple notes per site for technician context.
• Select saved sites during data entry to reduce typing.
• Use draft behavior to start a new measurement, then complete and save when ready.
• Keep list and detail visible side-by-side on iPad for faster editing.

Stats and trend review:

• Open per-site statistics in one tap.
• See minimum recorded values for key chemistry metrics.
• See maximum recorded values to catch risk spikes.
• See average values across saved records for baseline tracking.
• Review LSI movement over time for each property.

Spreadsheet and data handling:

• Browse records in a spreadsheet-style grid for high-volume review.
• Sort by column to inspect specific metrics quickly.
• Load data in batches for responsive performance.
• View up to 250 recent records in spreadsheet mode.

Export, sharing, and backup:

• Export record data as CSV for spreadsheet or reporting workflows.
• Export records as JSON for structured data transfer.
• Export full database JSON as a backup snapshot.
• Import database JSON to restore or merge saved data.
• Share exports directly to Files, Mail, Notes, and other iOS share targets.

Quick Calc mode for immediate checks:

• Use a separate local Quick Calc tab for fast device-side calculations.
• Keep quick-check values and last result in local storage.
• Share quick calculation output when needed.

Practical use cases:

• Daily pool service logs.
• Spa startup and balancing checks.
• Follow-up verification after chemical adjustments.
• Side-by-side before/after chemistry comparisons.
• Documentation for service reports and internal QA.

Built for iPhone and iPad field work:

• Fast tap targets and plain-language labels designed for techs in motion.
• iPad split layout helps teams compare record lists and details without constant back navigation.
• Integrated share flows reduce manual copy/paste when sending service documentation.
• Local-first storage keeps your workflow available where connectivity is inconsistent.
• Practical defaults help new entries start quickly, even on busy multi-stop routes.
