## Description

Log water parameters in seconds. Spot trends before problems. One-time purchase — no subscription.

Stop guessing if your tank is stable. Frag logs water parameters in seconds, shows trend charts with safe range bands, and reminds you before maintenance slips.

▸ LOG 10 PARAMETERS IN 10 SECONDS
Tap a cell, type a number, move on. pH, ammonia, nitrite, nitrate, temp, salinity, alkalinity, calcium, magnesium, phosphate — all logged before your test kit dries.

▸ SPOT TRENDS BEFORE PROBLEMS
Every parameter gets a trend chart with safe range bands. See drift at a glance — not just "what's my pH today" but "is my pH dropping?"

▸ NEVER MISS A WATER TEST
Smart reminders for water changes, filter cleaning, dosing, and testing schedules. Frag keeps track so you don't have to remember.

▸ TRACK YOUR WHOLE FISH ROOM
Multiple tanks, each with its own parameters, maintenance schedule, and livestock. Switch between tanks in one tap.

▸ KNOW BEFORE YOU ADD
Compatibility warnings flag species conflicts before you buy. Stocking calculator shows when your tank is approaching capacity.

▸ CORRELATE PARAMETERS
Overlay charts let you see two parameters side by side — spot cause and effect between alk, calcium, pH, temp, and more.

▸ SHARE & EXPORT
Share trend charts as images. Export parameter history as CSV for your records or your LFS.
