What Kyra is
A privacy-first trading journal for iOS focused on equities. Pattern detection runs on-device. Every pattern shows its sample size and an uncertainty range — the four tiers (Tracking, Hint, Signal, Proven) sharpen as your history grows, so claims stay honest about how much evidence supports them. Primary buyer: a retail self-executor who wants the gap between strategy and execution made visible. $4.99/mo or $39.99/yr after a 7-day trial.
What MyEdge is
MyEdge is a polished native workspace for journal, performance, and trading plan, by developer Alex Masure. It runs on iPad and Mac with universal SwiftUI, supports six asset classes (Forex, Futures, Stocks, Crypto, Options, CFD), and gives users editable taxonomies across five surfaces (Strategies, Tags, Biases, Qualities, Mistakes). Pattern surfacing happens via correlation dashboards on those user-editable taxonomies. Pricing is a one-time $29.99 lifetime unlock with a free tier capped at 30 trades per month.
How they compare
| Dimension | Kyra | MyEdge |
|---|---|---|
| Storage | On-device + iCloud user-private sync | On-device + iCloud sync |
| Asset classes supported | Equities (Stocks, Options at V1) | Forex / Futures / Stocks / Crypto / Options / CFD |
| Platforms | iOS | iOS / iPad / Mac (Universal) |
| Pattern detection approach | Sample-size-gated statistical inference, on-device | Correlation dashboards, no significance gate |
| Sample-size shown per claim | Yes — every pattern shows n and an uncertainty range | No |
| Taxonomy approach | Locked (8 emotions, 7 setups, 3 execution ratings) | User-editable across 5 surfaces |
| Pricing | $4.99/mo or $39.99/yr (subscription) | $29.99 one-time lifetime unlock |
| Free tier | Unlimited logging + strongest pattern | 30 trades/month, full input capture |
Who should pick which
Pick MyEdge if:
- You trade multiple asset classes (forex, crypto, futures, CFDs) and need a journal that covers all of them
- You want iPad + Mac coverage today
- You prefer a one-time payment over a subscription
- You want to define your own categorical taxonomies (custom mistake list, custom bias list, custom strategy tags)
- Your psychology of journaling is "capture every dimension I can think of" rather than "let the engine surface what matters"
Pick Kyra if:
- You want pattern claims with sample sizes and uncertainty ranges attached
- You want pattern claims that show their evidence — sample size and uncertainty range on every card — not correlation tiles without confidence framing
- You want a locked taxonomy (8 emotions, 7 setups, 3 execution ratings) that keeps the engine's inference clean across hundreds of trades, instead of bias chips that allow contradictory tags on one trade
- You trade equities primarily and don't need forex/crypto/futures coverage at V1
The trade-off
The privacy architecture is a tie. Both apps store trades on the device and sync through user-private iCloud. Neither is a cloud-LLM product.
The architectural difference is the engine. MyEdge ships custom factor taxonomies — user-editable, multi-axis, expressive — without an inference engine on top. Kyra ships a locked taxonomy with statistical inference on top. A custom factor without inference is a filter; with inference, it's a pattern signal. Pick the shape that matches what you want from the journal.
Pricing is a real consideration: MyEdge's $29.99 lifetime is cheaper than three years of Kyra's annual. The trade-off is whether ongoing development cadence (Kyra ships in a 30-day release rhythm) is worth the subscription. Both apps are run by individual developers; both choices are reasonable.
