## What is Backster?

Before you trade it, Backster it.

Describe a trading idea in plain English and Backster turns it into a real, runnable strategy — then shows you exactly how it would have played out on years of historical crypto data. No exchange account, no real money, nothing to lose but a bad idea.

DESCRIBE IT, DON'T CODE IT
Say it the way you'd think it — "buy when RSI drops below 30, take profit at 5%" — and Backster writes the real strategy code behind it. It's production-grade Freqtrade, the same open-source framework serious crypto traders use, not toy snippets. No programming required.

YEARS OF DATA, ANSWERED IN SECONDS
Backtest any strategy against years of real historical crypto markets in seconds. See every trade it would have made — the wins, the losses, and whether the idea actually holds up — before you ever risk a cent.

WATCH IT TRADE, RISK-FREE
Turn a strategy into a paper bot: a fully simulated trader that runs on live market data and shows you how it would perform in real time. All simulation, always. Never a dollar of real money.

TEST EVERYTHING, RISK NOTHING
Backster is built for learning. Test, tweak, and compare as many ideas as you want, and build real intuition for how strategies behave without ever putting money on the line.

PLANS
Backster is free to start. Pro, Max, and Ultra unlock a higher monthly usage allowance and 1, 3, or 6 concurrent paper bots. Subscriptions bill monthly through your Apple Account and renew automatically until cancelled in Settings.

IMPORTANT
Backster is an education and simulation tool. It is not a broker, does not connect to exchanges, does not execute real trades, and does not provide financial advice. Past (simulated) performance does not guarantee future results.

## Version history (last 5 releases)

### 1.2.2 — 2026-08-03

What's New in 1.2.2

• Paper bots now run on a new deterministic engine — launch a bot straight from any backtest and watch its equity curve build from real market history, trade by trade.
• Notifications, done right: we ask for permission at the right moment, and alerts for opened and closed positions now actually arrive on your device, grouped when multiple bots fire together.
• Before your trial starts, we'll show you exactly what the reminder will look like, so nothing about billing catches you by surprise.
• A faster path through onboarding, with clearer progress and a Skip button whenever you're ready.
• A clearer paywall, with a bigger close button and buttons that say what they do — "Start Free Trial" and "Subscribe Now."
• Launching a paper bot now confirms itself and takes you straight to the bot.

### 1.2.1 — 2026-07-20

What's New in 1.2.1
• A clearer look at your free trial: see exactly what happens on each day, and what's due today ($0.00) before you commit.
• Compare every plan in one place with "See all plans."
• We'll send you a reminder the day before your trial ends — no surprises.
• Paper bot improvements: tap a pinned bot to jump straight to it, clearer bot names and statuses.
• Bug fixes and clearer error messages.

### 1.2.0 — 2026-07-18

A completely new Backster. Guided strategy builder — build your first strategy in plain English, every choice a tap. Watch your backtest replay: your buys and sells on real history, versus just holding. Honest failure explanations when a strategy can't run. New design throughout. Plus: 3-day free trial on Pro and Max monthly plans.

### 1.0.1 — 2026-06-20

This release polishes the first run and makes a few things easier to reach:

- Smoother, clearer onboarding
- Quicker access to your plan and billing
- Send feedback to us right from Settings
- Fixes and refinements throughout

Keep the ideas and the feedback coming.
