What Kyra is
A privacy-first trading journal for iOS with classical statistical inference on-device. Patterns surface with n and an uncertainty range. No account required, no servers, no LLM processor. Free tier includes unlimited trade logging plus the single strongest detected pattern. Premium ($4.99/mo or $39.99/yr after a 7-day trial) unlocks the full pattern surface and the adaptive pre-trade checklist.
What TradeOrb is
TradeOrb ("Simple, customizable trade journaling for traders who want clarity, growth, and control"), by Hudson Ferreira, ships fast manual P/L-only entry, a P&L calendar grid, and an "AI Trading Insights" chatbot powered by an undisclosed LLM provider. The app requires email/password account creation (Firebase Auth). Pricing: $7.99/mo or $74.99/yr with a 7-day trial that's opt-in defaulted off. Dark mode and screenshot uploads sit behind the paywall.

Who should pick which
Pick TradeOrb if:
- You prefer an AI chatbot as your insights surface, regardless of sample size
- A polished P&L calendar grid with inline P/L cells is your primary requirement
- You want a refer-a-friend mechanic for sharing the app with other traders
- You're comfortable with email/password account creation and cloud-based storage
Pick Kyra if:
- You want pattern claims gated by sample size with an explicit uncertainty range — not LLM-generated commentary that can produce "Watch out for: Profit factor below 1" on a single winning trade with zero losers
- You want full trade editing on every field, not delete-and-recreate
- You want dark mode without a paywall, plus the rest of the app's cosmetics
- You don't want to create an account, set a password, or have trade data routed through an undisclosed LLM processor
- The annual price gap (Kyra $39.99 vs TradeOrb $74.99) is a real budget consideration
The trade-off
The architecture difference is the largest one. TradeOrb's account-required Firebase architecture means trades sit on a cloud database the developer operates; Kyra's on-device + iCloud-user-private architecture means trade data lives in your iCloud, not in any Kyra-operated service.
The insight-mechanism difference is the second one. TradeOrb's AI Trading Insights surface is an LLM commenting on your trades, which doesn't surface sample-size honesty by construction. Kyra's pattern engine waits for n to support a claim before promoting it across tiers.
Both products are competent for their target audience; the audiences are different.
