Your head is loud. Brain Dump gives it a blank page. Open the app and the cursor is already waiting. Write the thing that's bugging you, press Return, and it's out of your head and saved. No category to pick, no priority to set, no folder to find. Sort it later, or never. HOW IT WORKS Drop it in Write a thought and press Return. It lands in a loose pile at the top, ready for the next one. A burst of ten thoughts takes ten seconds. Sort what's loose When you have a minute, tap Sort. Thoughts come up one at a time, as a stack of slips. One tap files each as an Idea, Task, Note, Inspiration, Question or Random. Flag the urgent ones. Mark what's already done. Undo anything. Finish things Tasks get a checkbox. Swipe to complete or delete, with Undo. Finished thoughts fold away into a quiet "done" line, so the page shows what's still on your mind. Find anything Search as you type. Filter by category, priority or #tag in one tap. Your full history is always there and always searchable. BUILT TO FEEL CALM - Your thoughts are set in a serif typeface, like writing on paper. The app's own controls stay out of the way. - Warm paper in light mode, a soft charcoal desk in dark mode. - A home screen widget puts your latest thoughts a glance away, and one tap puts the cursor on the page. - No streak guilt. The daily reminder is optional and written to be kind. PRIVATE BY DESIGN Your thoughts live only on your device. No account, no sync, no one reading over your shoulder. Export everything to JSON or CSV whenever you like, and restore from a backup. FREE, AND GENEROUS Free forever: unlimited capture, all six categories and priorities, tags, pinning, daily reminder, full searchable history and export. BRAIN DUMP PRO Pro is the work the app does for you. - Open loops: questions you never answered and urgent things going stale, surfaced before they rot. - Your patterns: when your head is clearest, what you keep returning to, what you actually finish. - Echoes: the thought you keep having in different words. - On this day: old thoughts come back when they're useful again. - Your week: a short, honest read on what you captured and closed. - Photos on a thought, reminders on individual thoughts, and your own categories. Pro is available monthly, yearly or as a one-time lifetime purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period, and can be managed in your Apple ID settings. Any unused portion of a free trial is forfeited when you purchase a subscription. Brain Dump is for the people whose minds run ahead of them: ADHD brains, busy brains, creative brains, anyone who's ever had a great idea and lost it by the time they found a pen. Write it down. Let it go.

Stop Guessing. Start Growing with Precision. Whether you’re nurturing your first Monstera Albo or managing a diverse collection of rare aroids, Stemma provides the technical tools you need to track what actually matters: lineage, growth trends, and the financial value of your collection. I built Stemma because basic watering reminders aren't enough when you're dealing with high-stakes specimens. You need a way to track a plant’s history, its offspring, and its health with scientific accuracy. KEY FEATURES FOR THE SERIOUS GROWER AR GROWTH LOGS (THE "GHOST" VIEW): Create perfect time-lapses. When taking a growth photo, Stemma overlays a "ghost" of your previous image in the viewfinder. This allows you to line up every shot perfectly, so you can scroll through your logs and see exactly how that new leaf unfurled. VISUAL LINEAGE TREES: Never lose track of a cutting’s history. Map the genetic path from "Mother" to "Offspring" with clear, visual trees. Essential for anyone propagating rare variegates or tracking stable genetics across generations. FINANCIAL DASHBOARD: Treat your collection like the investment it is. Log purchase prices, track current market value, and monitor your ROI. Perfect for hobbyists who sell cuttings to fund their next "wishlist" plant. INTEGRATED LIGHT SENSOR: Stop guessing if your lighting is "bright indirect." Use your phone’s camera to measure exact Lux or Foot-candle levels right at the leaf surface. SUBSTRATE & LAB RECORDS: Keep a record of your custom soil mixes. Log which specimens are in "Aroid Gold," semi-hydro, or moss, so you know exactly what’s working for your specific environment. PERMANENT ARCHIVES: Keep the history of plants you’ve sold or gifted. Even after a specimen leaves your greenhouse, its lineage and care history stay in your records for future reference. ESSENTIAL TOOLS Action Logs: Record every watering and fertilization event. Custom Reminders: Set schedules tailored to your specific environment. Pro Exports: Generate CSV or PDF reports for your own tax records, insurance, or sales backups. Privacy First: Stemma is a local-first app. No accounts, no cloud tracking, and no data harvesting. Your photos and collection data stay on your device. From casual care to professional collection management, Stemma is the tool your plants deserve.

The clearest difference is iOS requirement: Brain Dump Tracker at 15.1 against Stemma's 17.0.1. On price, ads, in-app purchases and device support there is nothing between them.
