(Strategic Takeaway) {#so-what} Tide Chart USA is a weather app that is completely free. With a 4.77/5 rating from 8.1K reviews, it shows mixed user reception. > **Bottom Line:** Implementing manual location search would address the primary user complaint and stabilize the retention of the existing user base. The current maintenance-only posture risks losing the audience to more responsive, feature-rich weather utilities. **Best for:** Recreational anglers and boaters seeking quick, local tidal data. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Ship manual location search because it is the top-requested missing feature → reduce user churn ### Outlook: Declining Users report: The market for specialized boating utilities is consolidating around apps that provide high-accuracy, customizable data. Tide Chart USA's maintenance-only posture leaves it exposed to churn as users migrate to more reliable, actively updated alternatives. - 🔴 The seven-month development gap indicates a lack of active investment, which erodes user trust in the accuracy of the tidal data. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.77/5 | | Total Reviews | 8.1K | | Sentiment | Mixed (55/100) | | Confidence | Medium | | Pricing Model | Free | | Platforms | iOS | | Key Features | 1 analyzed | | Trend | Declining | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Tide Chart USA** (this app) | 4.77/5 | Mixed | hanitaro | | [Bauernkalender](https://marlvel.ai/apps/ch-swift-bauernkalender) | N/A/5 | N/A | Swift Management AG | | [Forecast & What to Wear](https://marlvel.ai/apps/com-appsforparents-weatherforkids) | 4.2/5 | N/A | Natalia Jakubczyk-Gajewska | | [Weather&Clothes](https://marlvel.ai/apps/com-air-weather_and_clothes) | 2.7/5 | N/A | fk.system | | [처음날씨 - 잠금화면 및 알람으로 오늘의 날씨를!](https://marlvel.ai/apps/com-woozuda-weather) | 4.2/5 | N/A | WOOZUDA | | [미세미세 - 미세먼지, 초미세먼지, 날씨](https://marlvel.ai/apps/cheehoon-ha-particulateforecaster-particulateforecaster) | 4.8/5 | Excited | LifeOverflow Inc. | ## Company Profile - **Developer:** hanitaro - **Website:** [https://app.hanitaro.com/](https://app.hanitaro.com/) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/tide-chart-usa/id593308377?uo=4) - **Dev Site:** [Official Website](https://app.hanitaro.com/) - **Sources:** Developer website content, App store metadata, User reviews. ## Related Intel Reports - [*Bauernkalender*](https://marlvel.ai/apps/ch-swift-bauernkalender) (Swift Management AG) · N/A Rating - [*Forecast & What to Wear*](https://marlvel.ai/apps/com-appsforparents-weatherforkids) (Natalia Jakubczyk-Gajewska) · 4.2/5 Rating - [*Weather&Clothes*](https://marlvel.ai/apps/com-air-weather_and_clothes) (fk.system) · 2.7/5 Rating - [*처음날씨 - 잠금화면 및 알람으로 오늘의 날씨를!*](https://marlvel.ai/apps/com-woozuda-weather) (WOOZUDA) · 4.2/5 Rating - [*미세미세 - 미세먼지, 초미세먼지, 날씨*](https://marlvel.ai/apps/cheehoon-ha-particulateforecaster-particulateforecaster) (LifeOverflow Inc.) · 4.8/5 Rating | Positive Sentiment - [*너의날씨: 미세먼지, 지도, 레이더, 캐릭터, 위젯*](https://marlvel.ai/apps/kr-guzi-yourweather) (구지랩(GuziLab)) · 5.0/5 Rating - [*ชายฝั่ง รู้ทันระดับน้ำ*](https://marlvel.ai/apps/hii-pttep-chaifang-mobile) (Hydro Informatics Institute) · 4.9/5 Rating - [*ภัยพิบัติไทย*](https://marlvel.ai/apps/biz-harmoniz-earthquake_alert_thai) (Harmoniz InterSoftware) · N/A Rating - [*13abc First Alert Weather*](https://marlvel.ai/apps/com-gray-wtvg-13abc-weather) (Gray Television Group, Inc.) · 4.6/5 Rating - [*13WarnMe*](https://marlvel.ai/apps/13warnme) (Local TV LLC) · 3.0/5 Rating ## Frequently Asked Questions {#faq} ### Is Tide Chart USA accurate for all coastal locations?
