A logbook for shrimp keeping. Grades, lineages, water quality & breeding. Whether you keep Neocaridina, Crystal Red, Taiwan Bee, or Sulawesi lines — ShrimpNote helps you track what spreadsheets and tank-only apps cannot: individual grade history, lineage names, and breeding records with photos. No subscription. No cloud account. Your collection stays on your iPhone. 【What You Can Do — Free】 ▷ Colonies (Tanks) Register up to 5 tanks with cover photo, species summary, lineage summary, shrimp count, environment notes, introduction date, and purchase price. Grade breakdown per colony (how many S / SS / SSS). ▷ Individual Shrimp Register up to 5 named shrimp with photo, species, variety, pattern, grade, lineage, generation, acquisition source & date, purchase price, identification memo, and status (keeping / breeding pair / rehomed / deceased). ▷ Grade Evaluation History Log grade judgments per shrimp — photo, grade label, date, and memo. Build a visual timeline of grade upgrades. Share any evaluation as an image card. ▷ Molt Log Record shell condition notes per individual. ▷ Water Quality & Water Changes Log temperature, pH, GH, KH, TDS, and memos.

Verdict
The clearest difference is ads: ShrimpNote at none against アクアリウムノート's shown. ShrimpNote also leads on iOS requirement (15.0 vs 18.0). On price, update cadence, in-app purchases and device support there is nothing between them.
