Pondlog
Your pond-farm logbook — feed, water checks, mortality and harvest profit, in any browser
Add each pond once, then keep daily records in seconds: feed kilograms and type, pH and dissolved oxygen, any mortality. At harvest, enter weight and price per kg and Pondlog shows gross income against feed spend and your feed-conversion ratio. Free, offline, no sensors.

What you can do in Pondlog on the web
Ponds and grow cycles
Name, area in m², species (tilapia, catfish, carp, shrimp, pangasius, snakehead, milkfish) and a stocking count and date to open each cycle.
One-tap daily feed log
Kilograms plus feed type — pellet, trash fish, rice bran, soybean meal, commercial mix — with a 14-day feed-per-day chart on every pond.
Water checks with status bands
pH and dissolved oxygen graded good / fair / poor against the 6.5–8.5 pH and ≥ 5 mg/L DO ranges, a pH trend line, and a home-screen alert when a pond slips.
Mortality and survival
Count each loss with a cause note; the cycle card keeps a running survivor count and survival percentage.
Harvest profit in one screen
Weight sold × price per kg minus the feed-cost estimate gives instant profit or loss, plus feed conversion ratio and days grown.
Farm stats across ponds
Feed per week, feed by type, cycles in progress and every harvested cycle's net result, with CSV and JSON export.
