About this app

Investing: If you don't record it, you repeat it.

The reason for buying, the timing of selling, the judgment of the day.

Ant's Investment Diary will remember for you the things that fade from memory over time.

‧ Investment Management

Simply search for the stock name and enter the investment start date.

You can grasp your portfolio at a glance by filtering by KOSPI, KOSDAQ, NYSE, NASDAQ, and ETF, as well as sorting by investment period, amount, and number of trades.

‧ Trading Journal

Record your buys and sells by date and leave notes.

If you write down the day's judgment and rationale, it becomes your own personal investment review notebook.

‧ Watchlist

Organize the stocks you are keeping an eye on by group and leave notes.

Recording your observations before buying helps you create better entry timing.

‧ Investment Statistics

Check the weight of your principal in your investment portfolio using a treemap and your investment weight by market using a pie chart.

You can review your investment patterns by viewing realized profit/loss and trading frequency at a glance. ‧ Community

Share investment stories with other retail investors.

You can freely write posts and share your thoughts with others through comments and likes.

‧ Easy Login

Get started in just 3 seconds using your Kakao, Naver, or Google account.
