Prediux
Read full descriptionHide full description
Most people aren't progressing. They are drifting. Prediux is for people tired of generic self-improvement apps that don't know them. An adaptive AI reads your real patterns, measures your drift, and writes one calibrated move each day — generated from your specific data, not pulled from a template. It is not a habit tracker. It is not a coach. It is a control panel for your own life: a diagnostic readout you consult daily to verify you are still aligned with where you said you wanted to go. THE DAILY RITUAL • Submit one signal against today's move — execution, energy, distraction. • The model recalibrates against your last seven days. • A new move is generated for tomorrow, tuned to your current state. • Your Control Index and Drift Risk update. The trajectory holds — or corrects. Every signal refines the model. Every missed day degrades it. The system gets sharper the longer you stay calibrated. WHAT YOU GET THE CORE A live readout of your current vector. Control Index, Drift Risk, status (Stable, Drifting, At Risk). Updates with every signal. TODAY'S MOVE One assignment a day, written by the AI from your specific seven-day history. No generic advice. No copy-paste protocols. THE FORECAST Where your current trajectory lands in 90 days if nothing changes, and what one daily signal can shift. THE WEEKLY READOUT Every Monday, a diagnostic recap. Net control, drift trend, best day, signals submitted, week-over-week comparison. THE STREAK Consecutive calibrated days. Break it and the model loses fidelity. Hold it and your forecast tightens. IT LEARNS YOU Every signal refines your moves, forecasts, and risk model. The output is calibrated to your patterns — not to a generic user. The longer you use Prediux, the more accurate the readout. WHO IT IS FOR Two kinds of people use Prediux: – Those who feel stuck, low-energy, or off-course and want a system that names the problem before pretending to solve it. – Those who already measure their lives and want a serious, instrumented tool that respects their time. Both share one trait: they don't want fluff. They want instrumentation. Entropy is the default. Without conscious daily input, you drift. Prediux measures the drift, names it, and corrects course — one signal, one move, one day at a time. Calibrated to you. Not to a generic user. SUBSCRIPTION A Prediux Pro subscription is required to access the features described above (Today's Move, Forecast, Weekly Readout, Streak, and the adaptive AI). • 3-day free trial included for new subscribers. • Subscription auto-renews and is charged to your Apple ID at the end of the trial unless cancelled at least 24 hours before it ends. • Subscriptions: $9.99/month or $79.99/year (prices may vary by country). • Manage or cancel anytime in iOS Settings → your Apple ID → Subscriptions. • No cancellation of the current subscription is allowed during the active subscription period.

Verdict
The clearest difference is ads: Melio at none against Prediux's shown. Melio also leads on update cadence (weekly vs fortnightly). On price, in-app purchases, device support and iOS requirement there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Prediux sells 2 in-app purchases, starting at $9.99 per month and Melio sells 3 in-app purchases, starting at $5.99 per 7 days. Whichever you choose, the download price is not the number that matters.
Prediux ships an update fortnightly, Melio weekly. Both last shipped on October 31, 2026.
