Connect to a Bluelab Pulse Meter for fast, accurate nutrient (EC), moisture and temperature measurements directly from the root zone, in soils, potting mixes, coco blends and other growing media types. The Bluelab Pulse app syncs real-time measurements direct from the Bluelab Pulse Meter for you to view, analyse, store and export your root zone data. Use the Bluelab Pulse app to: • VIEW MEASUREMENTS: View live updates on screen as you take measurements with the Pulse Meter. Take measurements from the button on Pulse Meter, or in the app. A single button press or tap gives you pore conductivity (nutrient EC), % moisture content (volumetric or % of max water holding capacity), and temperature. • TRACK MEASUREMENTS: View historic measurements for moisture, nutrient (EC) and temperature all time and date stamped. See your measurement history at a glance, identify trends, manage root zone performance, and see the results of your adjustments. • RECORD NOTES: Quickly add notes to the measurement history and track useful information such as measurement location, plant observations or operational task reminders. • MOVE FASTER: Set target nutrient and moisture ranges and quickly send to Pulse Meter. Use the Blink™ range indicators on Pulse Meter to quickly check if the measurement was in or out-of-range. Use the app to dive into the detail. • SYNC WIRELESSLY: Use Pulse Meter without the app to capture fast measurements and get quick feedback with Blink™. When back in range, Pulse Meter automatically syncs all new measurement data to the Pulse app. • CONFIGURE PULSE METER: Select the medium type you will be measuring in from the pre-set options in the app. Update Pulse Meter on-the-fly as you move between medium types. • CALIBRATE & OPTIMISE IRRIGATION: Calibrate Pulse Meter to the maximum water holding capacity of specific growing mediums for a more meaningful scale between maximum water holding capacity and the wilting point. Follow the simple in-app process to calibrate and store custom media calibrations. • GRAB & GO: Quickly pair to any Pulse Meter and get measuring • NOTIFICATIONS: Receive measurements to the lock-screen with customisable notification sounds. • EXPORT: Export all your measurement data to a .csv for further analysis. • IMPROVED CONNECTIVITY: New app and firmware improve connection stability

A collection app made for carnivorous plant growers. 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. With Bulk feeding, log one feeding for several plants at once. ▷ 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. ▷ Dormancy Set a dormancy start date and a target end date for each plant. A reminder on the target end date tells you it's time to check on it — handy for Venus flytrap and Sarracenia winter dormancy. ▷ Environment Log Daily records of temperature high/low, humidity percentage, and light hours. Track the seasonal conditions that matter for highland Nepenthes and Heliamphora. ▷ Growth Chart 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 to social media. Choose Square, Portrait, Story, or Landscape. Free users get a "Tracked with TrapNote" watermark; Pro removes it. ▷ Wishlist Keep your must-have species list with source, budget, and notes. When you land one, move it to your collection. ▷ Search, Filter & Sort Search by name, genus, species, clone name, or notes. Filter by genus, status, or plants for trade, and sort by date added, name, acquired date, or price. ▷ Trade Flags (Pro) Mark plants as available for trade and add a note on what you're looking for in exchange. ▷ 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 their plants season by season · Anyone maintaining a grow list in a spreadsheet · Growers who like to share their collection on social media 【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, environment logs, growth charts, wishlist, share cards (with watermark), and CSV/ZIP export & import are all free. · TrapNote Pro (one-time purchase): Unlimited plants + trade flags + watermark-free share cards.
