What Kyra is
A privacy-first trading journal for iOS. Trades stored on-device, optionally synced through user-private iCloud. Pattern detection runs locally and waits for sample size before claiming. Every pattern surfaces with n and an uncertainty range, gated by the four tiers (Tracking, Hint, Signal, Proven). $4.99/mo or $39.99/yr after a 7-day trial.
What TraderLens is
TraderLens (currently in beta at traderlens.app/en) is a web app by developer Alex Masure (also of MyEdge — see compare/myedge). It runs server-side, supports broker-connect trade ingestion, integrates a real-time economic calendar, and captures psychology via six sliders (Stress, Confidence, Focus default to 0/5), multi-select cognitive biases, and multi-select execution mistakes. A discipline score is derived from a self-reported binary dropdown averaged to a 10-point scale. "AI insights" are LLM-generated. Pricing: free during beta; Pro tier pricing not yet published.
How they compare
| Dimension | Kyra | TraderLens |
|---|---|---|
| Platform | iOS-native | Web app |
| Storage | On-device + iCloud user-private sync | Server-side |
| Account required | No | Yes (broker-connect implies account) |
| Pattern detection approach | Sample-size-gated statistical inference, on-device | "AI insights" (LLM), no significance gate |
| Sample-size shown per claim | Yes (n + CI, gated tiers) | Patterns "emerge at 50 trades" with no confidence framing |
| Asset classes | Equities (Stocks, Options at V1) | Forex / Stocks / Crypto |
| Discipline score | None | Self-reported binary dropdown averaged |
| Economic calendar integration | None | Real-time integration |
| Pricing | $4.99/mo or $39.99/yr | Free in beta; Pro pricing TBD |
Who should pick which
Pick TraderLens if:
- You journal from a browser, not a phone
- You trade multiple asset classes (forex, crypto, stocks) and want one tool to cover them
- You want broker-connect convenience, even at the cost of cloud storage
- A real-time economic calendar overlay is part of your workflow
- You want a free beta to evaluate before a paid commitment
Pick Kyra if:
- You journal from your phone — capturing the trade at the moment of the trade, not at end-of-day in a browser
- You want pattern claims with sample sizes and uncertainty ranges attached
- You want trade data to stay on the device, not on a developer-operated server
- You want a fixed psychology taxonomy (8 emotion states, 3 execution ratings, 4 context flags) that keeps inference clean rather than 6 sliders that default to mid-values and pollute the data
The trade-off
The platform choice is the largest one. A web app is fundamentally different from an iOS-native journal — different capture moment, different threat model, different ergonomics. If your workflow is browser-centric, Kyra is the wrong tool; if it's phone-centric, TraderLens is the wrong tool.
Both apps face the same psychology-tagging design problem. TraderLens chose breadth (6 sliders + multi-select biases + multi-select mistakes); Kyra chose discipline (8 fixed emotion states, 3 fixed execution ratings, 4 fixed context flags with explicit yes/no/null). Breadth maximizes expressiveness per trade; discipline maximizes inference cleanliness across hundreds of trades. Both are defensible choices; they fit different mental models.
