Built an iOS app to catch real-time crypto anomalies and volume spikes before they make the news

Hey guys,
Like many of you, I spent way too much time staring at charts, only to receive delayed notifications from mainstream apps after a massive move had already happened.
As a solo developer, I spent the last few months building CryptoWhistle to solve my own frustration. It just went live on the App Store.
Here is how it works under the hood and why it’s different:
1. Real-Time Engine (No Polling Delays)
Instead of relying on delayed API polling or simple price threshold triggers, the backend maintains a continuous real-time data stream directly from exchange feeds to detect unusual market behavior in milliseconds.
2. High-Precision Market Detection
Without revealing my exact algorithmic recipes, CryptoWhistle constantly monitors liquidity, volume dynamics, and orderbook behavior to catch market anomalies before they make the news:
- Unusual Volume Activity: Detects sudden capital inflows and outflows before traditional indicators react.
- Momentum & Volatility Spikes: Identifies sharp market breakouts and sudden dumps in real time.
- Orderbook Integrity: Analyzes market depth to filter out noise and spot significant liquidity shifts.
- Market Extremums: Tracks critical session breakouts and funding rate anomalies across supported pairs.
3. Absolute Privacy First
I didn't want another app collecting my data, so I built CryptoWhistle with zero registration requirements:
- No email, no passwords, no signup.
- Your device ID is completely anonymized.
- No personal data is ever tracked or stored.
4. Zero Configuration Needed
You don't need to configure complex thresholds or draw trendlines. You just add the coins you want to watch, organize them into custom strategy folders (Long / Short / Spot), and let the system run in the background.
Free vs. Pro Tier:
The app is built on a freemium model. The free tier is completely functional with real-time anomaly alerts for essential slots. The pro tier unlocks unlimited slots, custom strategy folders, and high-precision algorithmic filters.
Transparency Note:
CryptoWhistle is purely a data monitoring and market metrics tool. It doesn't tell you what to buy or sell, and it provides zero financial advice.
Since it's freshly launched, I’d love for you to check it out and give feedback. I’m here in the comments for any questions or feature requests.
