The world's first iOS app built for carnivorous plant collectors. Track your Nepenthes, Venus flytraps, Sarracenia, Drosera, Heliamphora, Cephalotus and more — with fields designed specifically for carnivores: pitcher size, feeding response, water type, and humidity. Replace your spreadsheet grow list with something that fits in your pocket. 【What You Can Do】 ▷ Plant Collection Register each plant with genus, species, clone name, source, acquisition date, price, and cover photo. Every entry in your grow list, organized as a proper ledger. ▷ Photo Timeline Add unlimited photos per plant from camera or library. Watch the growth of each pitcher, leaf, or trap unfold over time. ▷ Feeding Log Record prey type (fruit fly, mealworm, cricket, bloodworm, liquid fertilizer, other), size, trap used, whether it responded, and response time. Know which plants are catching well — and which need attention. ▷ Care Environment (per plant) Log setup type (terrarium, greenhouse, windowsill, outdoor), light source (LED, fluorescent, sunlight), and water type (distilled, rainwater, RO). Designed for carnivores — fertilizer is not on the list. ▷ Environment Log (Pro) Daily records of temperature high/low, humidity percentage, and light hours. Track the seasonal conditions that matter for highland Nepenthes and Heliamphora. ▷ Growth Chart (Pro) Pitcher size over time, plotted as a line chart per plant. See the trend from the day you acquired it. ▷ Share Card Generate a card with your plant's photo, species, clone name, pitcher size, growing status, and days tracked — and share it directly to Reddit, Instagram, or X. Free users get a "Tracked with TrapNote" watermark; Pro removes it. ▷ Wishlist Keep your must-have species list. Add source, target price, and notes. Never lose track of a species you're hunting. ▷ Trade Flags (Pro) Mark plants as available for trade and add a note on what you're looking for in exchange. Useful when posting to r/SavageGarden or TerraForums trade threads. ▷ CSV / ZIP Export & Import Export your full collection as CSV, or as a ZIP with photos. Import CSV or ZIP to restore data. Available on the free plan. 【Who It's For】 · Nepenthes collectors with highland setups or terrariums · Venus flytrap and Sarracenia growers tracking pitcher size season by season · Anyone maintaining a grow list in a spreadsheet or Notion · Community members who post their collection to r/carnivorousplants, Instagram, or X 【Your Data Stays on Your Device】 All data is saved locally on your iPhone. Nothing is sent to external servers. No account required. No subscription. No risk if a service shuts down. 【Pricing】 · Free: Up to 10 plants. Photo timeline, feeding logs, wishlist, share cards (with watermark), and CSV/ZIP export & import are all free. · TrapNote Pro (one-time purchase): $6.99. Unlimited plants + environment logs + growth charts + trade flags + watermark-free share cards. Pay once, yours forever. ---------------------- Developer: Kore Apps Contact: support@kore-apps.com ----------------------
