Pool vs Daybreak

Stop guessing. Stop Googling. Pool-Proof walks you step-by-step through a complete spa or hot tub water chemistry session using Taylor K-2006 Platinum test kit methodology — the gold standard used by pool professionals. THE RIGHT ORDER, EVERY TIME Water chemistry is order-dependent. Balancing pH before alkalinity causes instability. Adding chlorine when pH is acidic corrodes equipment. Pool-Proof enforces the correct sequence: Free Chlorine, Total Alkalinity, pH, Calcium Hardness. Every time, without fail. PRECISE DOSE RECOMMENDATIONS Pool-Proof calculates exactly how much of each chemical to add — baking soda, muriatic acid, liquid chlorine, Cal-Hypo shock, dry acid, sodium carbonate (soda ash), calcium increaser, or granular bromine. Every dose follows the 50% Staged Dosing rule: add half the calculated amount, run jets for 45 minutes, then re-test. This prevents chemical bounce and over-treatment. Dose cards show liquid amounts in fl oz and mL, plus granular equivalents in household measures (tsp, tbsp, cup) — so you can use whatever product you have on the shelf. THE LSI SCORE The Langelier Saturation Index (LSI) is your water balance report card. Pool-Proof calculates it using CYA-corrected alkalinity per Taylor K-2006 methodology. A large color-coded score — from corrosive to scaling — gives you the full picture at a glance. CHLORINE & BROMINE Switch between chlorine and bromine mode from the Setup screen. Bromine mode adjusts all target ranges, skips CYA correction, and uses the correct dosing rates for granular bromine automatically. WET-HAND FRIENDLY Built for poolside use. Giant tap targets. Physical-style +/- drop counters that mirror the real test kit workflow. No tiny keyboard fields. Dark theme for outdoor readability. THE VAULT Save every test session. Review past LSI scores and readings. Spot trends over time. All history is stored privately on your device — no account required, no cloud sync. BUILT-IN SAFETY GUARDRAILS Pool-Proof includes the same safety rules professional techs follow: pH gate — chlorine dosing blocked when pH is below 7.0 Alkalinity guardrail — emergency baking soda forced when effective alkalinity drops dangerously low Acid cap — muriatic acid limited to a safe maximum per treatment cycle TA-first logic — pH corrections deferred until alkalinity is balanced FLEXIBLE FOR ANY SPA Gallons or liters volume input F or C temperature toggle Liquid or granular dose format preference Basic Mode (acrylic or fiberglass spa) or Pro Mode (plaster pool, full LSI and calcium hardness) Chlorine or bromine sanitizer COMPLETELY PRIVATE All data is stored locally on your device. No login. No subscription. No data collection. Nothing ever leaves your phone. Works with the Taylor K-2006 Platinum test kit. Trusted methodology. No guesswork. DISCLAIMER: Pool-Proof is a calculation aid designed to assist with routine residential spa maintenance. It does not replace professional water testing or licensed pool service technicians. Always follow chemical product labels and safety precautions.

The default Clock handles alarms. Daybreak handles schedules. Build reusable routines, adjust one day, and keep the rest of your week intact. Plan the Week See your next alarm and the shape of the week in one clear schedule. Reuse Routines Build a group once, assign it to weekdays, and stop recreating the same alarms by hand. Change One Day Adjust a single day, then restore the default when the exception is over. Add One-Offs Place a loose alarm on any day when it does not belong in a routine. Pause with Dates Use Calendar and Schedule Pauses for trips, holidays, and time off. Protect Your Setup Back up your full schedule or share a group template with another Daybreak user. Why Daybreak Clock is built for isolated alarms. Daybreak is built for repeating weeks. Your standing schedule and your one-day changes stay separate, so small edits do not unravel the rest of the week. Pauses, backups, and templates add depth without turning the app into a rule engine. Set the routine. Change the day. Keep the week. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period.
