The lack of public ratings suggests an early-stage market presence that requires immediate social proof to scale. ## Monetization Strategy - **Model:** Freemium - **Tiers:** Free tier with 5 tests per day, Pro subscription (monthly/annual) for unlimited access - **Analysis:** The freemium model uses a daily usage cap to drive conversion to Pro, with a 7-day free trial offered on the annual plan. ## SWOT Analysis {#swot} **Core Strengths:** - On-device AI generation removes data-privacy friction - Integrated BOE legislation tracker functions as a high-value utility - FSRS spaced repetition algorithm provides a scientific retention mechanism **Growth Levers:** - B2B partnerships with civil service academies - Gamified study streaks to improve retention ## Recent Changes (v2 → v3) {#recent-changes} The report reflects a shift in strategy from funnel optimization to social feature development, alongside a more critical assessment of the app's maintenance-mode development pace. **Overall trend**: Mixed **Compared at**: 2026-08-12 ### High-impact changes - **[Shifted] Privacy architecture re-evaluated** (positioning) - **[Shifted] PM strategy pivot** (positioning) ### Medium-impact changes - **[Added] New competitive weaknesses and threats** (swot) ## What's New - **Latest (v1.3.9, 1 months ago):** Added daily reminder activation during onboarding and a new dashboard card prompting users to take their first practice exam. ## App Momentum (Maintenance) {#momentum} - Shipped daily reminders in latest release. - Ships ~10 updates per year. > **Cadence:** 1 total versions · 1 majors in last 6 months · 36 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} Opositor: Tests y Simulacros is an education app that is free with in-app purchases. > **Bottom Line:** Opositor secures its niche with on-device AI and deep legislation integration, but the lack of social study features and slow update cadence leaves it exposed to more dynamic rivals, so the PM should prioritize a community-driven study loop to boost retention. **Best for:** Individuals preparing for Spanish civil service examinations who require structured study materials and official exam simulations. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Ship social study groups because the current solitary experience lacks retention loops → increase daily active usage ### Outlook: Stable The civil service prep market is consolidating around tools that offer social study features and high-frequency live-ops. Opositor's current posture is stable but exposed, as the lack of community-driven retention loops makes it vulnerable to competitors with stronger social mechanics. - ⚪ The 36-day update cadence indicates a stable, maintenance-focused product that lacks the aggressive iteration needed to capture market share from faster rivals. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Total Reviews | 0 | | Confidence | Low | | Pricing Model | Freemium | | Platforms | iOS | | Key Features | 3 analyzed | | Trend | Mixed | | Outlook | Stable | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Opositor: Tests y Simulacros** (this app) | N/A/5 | N/A | Juan Miguel Marques Morilla | | [AlgoApp - Flashcards](https://marlvel.ai/apps/algoapp-flashcards) | 4.5/5 | n/a | AlgoApp Inc | | [Elevate - Brain Training Games](https://marlvel.ai/apps/elevate-brain-training-games) | 4.7/5 | n/a | The Mind Company | | [Flashcards Deluxe](https://marlvel.ai/apps/flashcards-deluxe) | 4.5/5 | N/A | OrangeOrApple.com | | [Flash Cards Flashcards Maker](https://marlvel.ai/apps/flash-cards-flashcards-maker) | 4.0/5 | Mixed | Infinite Wave Media, LLC | | [Flashcards maker - AI generate](https://marlvel.ai/apps/flashcards-maker-ai-generate) | 4.1/5 | Mixed | Teleprompter LLC | ## Company Profile - **Developer:** Juan Miguel Marques Morilla - **Website:** [https://opositor.web.app](https://opositor.web.app) ## Data Sources & Links - **App Store ID:** 6761821165 - **Dev Site:** [Official Website](https://opositor.web.app) - **Sources:** Developer website content, App store metadata. ## Related Intel Reports - [*AlgoApp - Flashcards*](https://marlvel.ai/apps/algoapp-flashcards) (AlgoApp Inc) · 4.5/5 Rating - [*Elevate - Brain Training Games*](https://marlvel.ai/apps/elevate-brain-training-games) (The Mind Company) · 4.7/5 Rating - [*Flashcards Deluxe*](https://marlvel.ai/apps/flashcards-deluxe) (OrangeOrApple.com) · 4.5/5 Rating - [*Flash Cards Flashcards Maker*](https://marlvel.ai/apps/flash-cards-flashcards-maker) (Infinite Wave Media, LLC) · 4.0/5 Rating - [*Flashcards maker - AI generate*](https://marlvel.ai/apps/flashcards-maker-ai-generate) (Teleprompter LLC) · 4.1/5 Rating - [*Impulse - Brain Training*](https://marlvel.ai/apps/impulse-brain-training) (GMRD Apps Limited) · 4.6/5 Rating - [*Peak - Brain Training*](https://marlvel.ai/apps/peak-brain-training) (Synaptic Labs) · 4.7/5 Rating - [*자주 틀리는 우리말*](https://marlvel.ai/apps/app--424) (DaolSoft, Co., Ltd.) · N/A Rating - [*달공부 - 한 달 공부 다이어리 + 루틴/공부 타이머*](https://marlvel.ai/apps/azlabs-dalstudy) (SuWon Choi) · N/A Rating - [*타요콘 - 타요 아바타 놀이동화*](https://marlvel.ai/apps/com-kigle-project-tayocon) (KIGLE) · 3.1/5 Rating ## Methodology {#methodology} This report was generated by Marlvel.ai's 5-stage AI intelligence pipeline: 1. **Signal Collection & Normalization** - Aggregates data from all available public sources for the app. Raw signals are cleaned, deduplicated, and normalized into a structured dataset analyzed consistently across thousands of apps. 2. **Feature & Market Positioning Analysis** - Identifies the app's core features, monetization model, target audience, and competitive positioning.
