It holds a 4.35/5 rating from 20 reviews. > **Bottom Line:** Karekök Video Çözüm serves as a functional textbook companion, but the lack of content updates and reported inaccuracies undermine its utility. Addressing these quality issues would stabilize the user base, as the app's value is entirely dependent on the accuracy of its solutions. **Best for:** Students preparing for exams who use Karekök-branded textbooks and require supplemental video explanations. ### PM Action Plan (Next Best Moves) - [ ] [MAINTAIN] Audit content accuracy because user complaints flag incorrect practice questions → improve retention ### Outlook: Declining The education utility market is shifting toward interactive, frequently updated content, leaving Karekök Video Çözüm exposed due to its static, maintenance-only posture. Without a commitment to content accuracy and regular updates, the app risks becoming obsolete for students who require current, reliable exam preparation. - 🔴 The 10-month update silence suggests the publisher is deprioritizing the digital experience, which will likely accelerate user churn as exam requirements evolve. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.35/5 | | Total Reviews | 20 | | Sentiment | Frustrated (25/100) | | Confidence | Medium | | Pricing Model | Free | | Platforms | iOS | | Key Features | 3 analyzed | | Trend | Stable | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Karekök Video Çözüm** (this app) | 4.35/5 | Frustrated | FERNUS BILISIM HIZMETLERI EGI.DAN. ve TIC.LTD.STI. | | [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:** FERNUS BILISIM HIZMETLERI EGI.DAN. ve TIC.LTD.STI. - **Website:** [https://www.fernus.com.tr](https://www.fernus.com.tr) - **Social:** [Instagram](https://www.instagram.com/fernusbilisim) · [Facebook](https://www.facebook.com/fernusbilisim) · [X/Twitter](https://www.twitter.com/fernusbilisim) · [LinkedIn](https://www.linkedin.com/company/fernus) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/karek%C3%B6k-video-%C3%A7%C3%B6z%C3%BCm/id1422389243?uo=4) - **Dev Site:** [Official Website](https://www.fernus.com.tr) - **Sources:** Developer website content, App store metadata, User reviews. ## 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 ## Frequently Asked Questions {#faq} ### Is Karekök Video Çözüm free to use?
