(Strategic Takeaway) {#so-what} imiwa? is a market-leading reference app that is completely free. With a 4.75/5 rating from 226 reviews, it delivers strong user satisfaction. > **Bottom Line:** Imiwa? remains a reliable reference tool for advanced learners, but the lack of updates threatens its long-term viability. Addressing search field glitches and adding flashcard export would unlock significant value for the existing user base without requiring a full platform rebuild. **Best for:** Japanese language learners ranging from beginners using the SKIP method to advanced students requiring sentence analysis. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Ship flashcard export functionality because it is the top-requested feature → increase long-term user retention ### Feature Gaps vs Competitors - OCR camera search (available in English Dictionary - Offline but absent here) ### Outlook: Declining The Japanese dictionary market is consolidating around tools that integrate real-time translation and AI-based pronunciation feedback. Imiwa? remains exposed due to its maintenance-only posture, and without a targeted update to address search field stability, it will likely lose its remaining active user base to more responsive, feature-rich competitors. - 🔴 The five-year update gap erodes platform trust, as interface glitches on newer hardware remain unaddressed by the developer. - 🔴 Competitor adoption of OCR and AI speech analysis creates a convenience gap that drains the casual learner funnel. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.75/5 | | Total Reviews | 226 | | Sentiment | Thrilled (85/100) | | Confidence | High | | Pricing Model | Free | | Platforms | iOS | | Key Features | 2 analyzed | | Trend | Stable | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **imiwa?** (this app) | 4.75/5 | Thrilled | Pierre-Phi di Costanzo | | [Banter (Prev Jojo AI)](https://marlvel.ai/apps/com-refond-speak) | 4.7/5 | N/A | Read Bean | | [국립국어원 표준국어대사전](https://marlvel.ai/apps/com-daolsoft-stdkorean) | 4.2/5 | N/A | DaolSoft, Co., Ltd. | | [Eijiroid](https://marlvel.ai/apps/com-eijiroid-inapp) | 3.6/5 | N/A | Eijiroid | | [Nuva - English Tutor](https://marlvel.ai/apps/com-nexuskairos-nuva) | 5.0/5 | N/A | Nexus Kairos LLC | | [Duolingo English Test (DET)](https://marlvel.ai/apps/com-duolingo-detmobile) | 3.1/5 | N/A | Duolingo | ## Company Profile - **Developer:** Pierre-Phi di Costanzo - **Website:** [https://www.imiwaapp.com](https://www.imiwaapp.com) - **Social:** [X/Twitter](https://twitter.com/intent) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/imiwa/id288499125?uo=4) - **Dev Site:** [Official Website](https://www.imiwaapp.com) - **Sources:** Developer website content, App store metadata, User reviews. ## Related Intel Reports - [*Banter (Prev Jojo AI)*](https://marlvel.ai/apps/com-refond-speak) (Read Bean) · 4.7/5 Rating - [*국립국어원 표준국어대사전*](https://marlvel.ai/apps/com-daolsoft-stdkorean) (DaolSoft, Co., Ltd.) · 4.2/5 Rating - [*Eijiroid*](https://marlvel.ai/apps/com-eijiroid-inapp) (Eijiroid) · 3.6/5 Rating - [*Nuva - English Tutor*](https://marlvel.ai/apps/com-nexuskairos-nuva) (Nexus Kairos LLC) · 5.0/5 Rating - [*Duolingo English Test (DET)*](https://marlvel.ai/apps/com-duolingo-detmobile) (Duolingo) · 3.1/5 Rating - [*English Dictionary - Offline*](https://marlvel.ai/apps/english-dictionary-offline) (ZeeAlpha Tech) · 4.6/5 Rating | Excellent Sentiment - [*English Dictionary - LDOCE*](https://marlvel.ai/apps/english-dictionary-ldoce) (Nguyen Thi Hoai Thu) · 4.8/5 Rating - [*Articulate: Speech Trainer*](https://marlvel.ai/apps/articulate-speech-trainer) (Anton Sorokin) · N/A Rating - [*Learn Persian (Beginners)*](https://marlvel.ai/apps/learn-persian-beginners) (BNR LANGUAGES INC.) · 4.5/5 Rating - [*Learn Arabic (Beginners)*](https://marlvel.ai/apps/learn-arabic-beginners) (BNR LANGUAGES INC.) · 4.6/5 Rating | Positive Sentiment ## Frequently Asked Questions {#faq} ### Is Imiwa? still a good dictionary for Japanese learners in 2026?
