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, Emerging, Developing, Established) 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 Nara is
Nara is a free iOS journal built around a fast single-form log and a per-trade emotion picker (calm, FOMO, revenge, per its listing), with a calendar of winning and losing days and a "Pattern Insights" view. In the version we reviewed hands-on (June 2026), insights showed win rate by strategy and simple correlations with labels like "Signal" and badges like "LOW CONFIDENCE" or "NEEDS DATA," unlocking together after 10 logged trades. Data is stored on the device with no account and no iCloud sync. Note that its App Store privacy label lists identifiers as data that may be used to track you across other companies' apps and websites. There is no paid tier (App Store listing, 2026-09-05).
How they compare
| Dimension | Kyra | Nara |
|---|---|---|
| Storage | On-device + iCloud user-private sync | On-device (offline only); privacy label lists identifiers used for tracking |
| Account required | No | No |
| Sync across devices | iCloud user-private sync | None (single device) |
| Pattern approach | Sample-size-gated statistical inference; each label is earned per pattern | Win rate plus simple correlations; descriptive labels (June 2026 review) |
| Confidence labels | Earned tiers (Emerging → Developing → Established); a pattern reaches one only once its result is statistically significant | Descriptive tags like "Signal" styled on the raw win rate (June 2026 review) |
| Sample size shown per claim | Yes — n and an uncertainty range on every pattern | Trade count shown; no per-pattern significance test (June 2026 review) |
| Gamification | None | Streaks (journaling, win-streak, positive-day) and notifications (June 2026 review) |
| Pricing | $4.99/mo or $39.99/yr (free tier included) | Free |
| Platforms | iOS | iOS |
Who should pick which
Pick Nara if:
- You want a free, fast, offline log and don't need cross-device sync
- You want a simple win-rate-by-strategy view with no subscription
- You only journal on one device
Pick Kyra if:
- You want a confidence label to be earned — a tier a pattern reaches only after passing a significance test, with the sample size on the card — not a tag on a raw win rate
- You want your history to sync privately through iCloud without creating a Kyra account
- You want the engine to gate each pattern by how much evidence supports it, not label every win rate
The trade-off
Both apps keep trade data on the device, and Nara is free and ships a P/L calendar today. If those are what you need, it is a reasonable pick.
The difference is the engine under the vocabulary. In the version we reviewed, Nara styled a tag like "Signal" onto a raw win rate. In Kyra, a pattern only climbs to a tier like Developing or Established once its result is statistically significant, and the sample size rides on the card. If a confidence label should be earned rather than styled, that is the line between them — here is the math behind every pattern and how pattern detection works.
Nara details reflect its App Store listing as checked on 2026-09-05, plus a hands-on review in June 2026 where noted. Features and pricing change; verify current details with the developer. Kyra details reflect v1.7.
