About Blindgrade and React-Ionic

In their own words, as submitted to SaaSHub.

Blindgrade
React-Ionic

Blindgrade is chart replay practice with the ticker and dates taken off. You get a real historical chart, trade it with paper money as the candles play out, and get graded on what you did: entry, size, where the stop went. Then the reveal shows what the chart was. Why blind: a replay on a chart...

No features have been listed yet.

  • Cross-Platform Development
    React-Ionic allows developers to build applications that run on both iOS and Android platforms using a single codebase, effectively saving time and resources.
  • React Ecosystem
    Integration with the React ecosystem provides access to numerous libraries and tools, allowing developers to use familiar technologies and streamline the development process.
  • Ionic Components
    Leverages Ionic's UI components that are designed to look and feel native on both iOS and Android, providing a consistent and polished user experience across platforms.
  • Live Reloading
    Features like live reloading and hot module replacement can speed up the development process by allowing developers to see changes in real-time.
  • Community Support
    Being part of the larger React and Ionic communities, developers can tap into extensive community support and resources to help solve issues and improve their applications.

Possible disadvantages

  • Performance Overhead
    Applications built with React-Ionic may experience performance overhead compared to fully native apps, which can be a concern for performance-intensive applications.
  • Learning Curve
    Developers new to the ecosystem might face a learning curve due to the combination of React and Ionic concepts and components.
  • Platform-Specific Customization
    While React-Ionic provides cross-platform functionality, achieving platform-specific look and feel or leveraging native features can require additional customization and work.
  • Ecosystem Dependence
    Reliance on both the Ionic framework and React means developers must stay current with updates and changes in both ecosystems, which can cause maintenance challenges.
  • Bundle Size
    The inclusion of both React and Ionic libraries can lead to larger application bundle sizes, which might impact load times and performance on lower-end devices.

Questions & Answers

As answered by people managing Blindgrade and React-Ionic.

What makes your product unique?

Blindgrade's answer

Blindgrade hides the ticker and the dates on every replay. On other replay tools you pick the chart, so you often know how it ends: if it's Bitcoin in March 2020, you know the crash is coming. On Blindgrade you trade real historical candles without knowing what they are, so the only thing you can trade is what's on the screen. Each round is graded on your process: entry, size and where the stop went, not just profit. A live AI mentor marks habit-level mistakes on the chart while the candles are still playing. It sees only what you see and never tells you which way to trade.

Why should a person choose your product over its competitors?

Blindgrade's answer

Replay tools like FX Replay and TradingView's Bar Replay are good for backtesting a strategy on a chart you choose. Blindgrade is for practising the decision itself, without hindsight to lean on. It runs in the browser with no install. The daily chart needs no account. A free account gets 15 practice rounds a week, with the AI mentor on 3 of them. Pro is $79 a year, less than most replay subscriptions charge for a few months. It adds unlimited practice, the mentor on every round, replay of any symbol from any date (blind or not), and full analytics.

How would you describe the primary audience of your product?

Blindgrade's answer

Newer and intermediate traders who want to get better at trading without risking money. Most are crypto traders who have watched tutorials and want repetitions with feedback before they trade live. It also suits experienced traders who use replay tools and want to check whether their reads hold up when they can't recognise the chart.

What's the story behind your product?

Blindgrade's answer

Blindgrade is built by a solo developer and trader. Practising on replay kept running into the same problem: on a chart you can identify, you already half-know the ending, so a good trade proves nothing. Blindgrade started as a daily mystery chart, the same hidden chart for everyone each day, in the style of Wordle. Practice rounds came next, then grading on process, then a live AI mentor. It has been in public beta since September 2026.

Which are the primary technologies used for building your product?

Blindgrade's answer

TypeScript, React, KlineCharts for the charts, Node.js with Fastify, and PostgreSQL. The live AI mentor runs on large language models. Every number it quotes is measured by Blindgrade's own trading engine, not written by the model
