What Kyra is
A privacy-first trading journal for iOS. Trades stored on-device. Pattern detection runs locally and waits for sample size before claiming — every pattern surfaces with n and an uncertainty range. The four tiers (Tracking, Emerging, Developing, Established) sharpen as your history grows. No streaks, no badges, no achievement chrome. $4.99/mo or $39.99/yr after a 7-day trial.
What Proloca is
Proloca ("You're not losing because of your strategy. You're losing because you can't see your own patterns") is an iOS journal that leads with a daily self-diagnosis at onboarding and frames the journal around behavioral inputs: psychology sliders (Stress, Confidence, Focus), per-trade emotion tags, and a multi-select execution-mistakes list, with a P&L calendar, winning streaks, and profit goals (per its listing). Its App Store privacy label lists no data linked to identity. In the version we reviewed hands-on (May 2026), patterns surfaced at low sample sizes without a stated significance test, and achievement badges fired after a single trade. Pricing on the listing (2026-09-05): Pro at $3.49/week, $8.99/month, or $49.99–$59.99/year; a Journal tier at $2.99/month or $19.99/year.
How they compare
| Dimension | Kyra | Proloca |
|---|---|---|
| Storage | On-device + iCloud user-private sync | Privacy label: no data linked to identity |
| Pattern surfacing | Sample-size-gated; engine waits for enough evidence before claiming | Patterns at low sample sizes; no significance test shown (May 2026 review) |
| Onboarding | Detects patterns from your trades | Self-diagnosis of your "failure mode" before trade 1 |
| Streaks / badges / achievements | None (deliberate — see manifesto) | Streaks, highlights, and achievement events |
| KPI on a single trade | None — engine waits for n | Win-rate KPI shown after one trade (May 2026 review) |
| Pricing | $4.99/mo or $39.99/yr — 2 SKUs | Pro $3.49/wk, $8.99/mo, $49.99–$59.99/yr; Journal $2.99/mo, $19.99/yr |
| In-app feedback form | Mailto deep link | Structured category-pills + text |
| P&L Calendar | No | Default landing |
Who should pick which
Pick Proloca if:
- You like daily-routine UX with achievement badges and streak visibility
- A weekly subscription option ($3.49/wk) fits your budgeting style
- Front-loaded self-diagnosis ("what's costing me?") helps you focus the journal from day 1
- A P&L Calendar as the default landing is a hard requirement
Pick Kyra if:
- You want pattern claims gated by sample size and statistical significance — not a win-rate label on a single trade
- You want the engine to detect what's costing you, instead of pre-tagging it yourself before you've logged a trade
- You don't want streaks or badges in a trading app (Kyra's manifesto explains why it leaves them out)
- You want a sober UI optimized for accurate inference, not for engagement metrics
The trade-off
The positioning surfaces overlap almost exactly. Both apps tell the trader: "you can't see your own patterns yourself; this app will surface them." The difference is mechanism.
Proloca optimizes for daily engagement: streaks, badges, achievement events. Kyra leaves those out on purpose; the manifesto explains why.
Kyra optimizes for sample-size-honest inference: patterns wait until n supports them. The downside is structural — early sessions show ghost cards instead of claims. A trader who needs the journal to feel rewarding from day 1 will be happier on Proloca. A trader who values claims they can act on without second-guessing will be happier on Kyra.
Pricing is also a real consideration: Proloca's weekly Pro tier ($3.49/wk, about $181/yr if kept all year) is roughly 4.5× Kyra's annual; its annual tiers are comparable to or above Kyra's. Pick the SKU that matches your commitment shape.
