Description by LEAN ASIA CO., LTD Written by the developer, not by AppBrain. Click to read.
PREMIUM — PURCHASE REQUIRED: All features described below are part of Pro and require a purchase: a weekly or yearly auto-renewing subscription, or a one-time lifetime purchase.

StockNotes is a trading journal and stock research log built for one job: recording why you buy, why you sell, and what you learned - before the market makes you forget.

Your broker shows you what you did. StockNotes captures why. Write an investment thesis with a bull case and a bear case for every ticker, rate your conviction, set buy and sell targets, run a due-diligence checklist before you commit, and log every trade with your reasoning and a reflection once it closes. Everything in it is typed by you - no brokerage login, no live feeds, no noise.

WHAT YOU GET
• A watchlist that flags when a stock has dropped below your own buy target - your plan waiting for you when you open the app
• Every position argued both ways: thesis, bull case and bear case side by side, so you always know what would prove you wrong
• A trade log that pairs each buy or sell with the reasoning you had that day - and the reflection you add after the outcome
• Your real win rate, sector mix, allocation and conviction spread in clear charts, computed from your own entries
• Due-diligence checklists (quality, value, pre-trade) plus a position size calculator, so no order goes in on impulse
• One-tap export: a formatted research note per stock and your full trade journal as CSV

PERFECT FOR
• Long-term investors who write the thesis before they place the order
• Swing traders who want to see which setups actually make money
• Anyone rebuilding discipline after a run of emotional trades
• Learners following the built-in guides on thesis writing, position sizing and journaling, sourced from Investor.gov, FINRA and the CFA Institute

WHY NOT JUST A SPREADSHEET?
A spreadsheet holds numbers; it never asks questions. StockNotes structures every entry - thesis, targets, conviction, checklist, reflection - so that six months from now you can reread your reasoning, not just your P&L.

PRIVATE BY DEFAULT
No account, no brokerage connection, no market data pulled in. Your research and trade notes are stored on your device and leave it only when you choose to export them. StockNotes is a note-taking tool; it does not provide investment advice, price data or recommendations.

PREMIUM (PURCHASE REQUIRED)
StockNotes Pro unlocks the complete watchlist with conviction, buy/sell targets and upside, the full trade journal with reasoning and reflection, all due-diligence checklists and the position sizer, bull and bear cases with tags and allocation notes, every insight chart, and export. Choose a weekly or yearly subscription, or a one-time lifetime purchase.

Start tonight: add one ticker, write one honest thesis, and set the price you would actually buy at.
