It holds a 4.55/5 rating from 11 reviews. > **Bottom Line:** Istanbul Guide & Tours provides a functional offline utility, but the multi-year maintenance freeze leaves it vulnerable to platform-level deprecation. The PM should prioritize a stability audit to determine if the codebase can support modern OS requirements before considering new route content. **Best for:** Independent travelers visiting Istanbul who prioritize offline functionality and self-guided, time-optimized walking tours. ### PM Action Plan (Next Best Moves) - [ ] [MAINTAIN] Audit codebase compatibility because the 86-month update gap risks total failure on modern iOS versions → determine viability ### Outlook: Declining The travel utility market is consolidating around apps that offer real-time transit data and live-ops content updates. Istanbul Guide & Tours remains static, which leaves it exposed to churn as modern devices and OS requirements evolve beyond the 2019 build. - 🔴 The 86-month release gap indicates the product is in a zombie state, which erodes user trust and platform compatibility over time. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.55/5 | | Total Reviews | 11 | | Confidence | Low | | Pricing Model | Freemium | | Platforms | iOS | | Key Features | 3 analyzed | | Trend | Stable | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Istanbul Guide & Tours** (this app) | 4.55/5 | N/A | GUIDELING OU | | [กิจวัตรมุสลิมไทย](https://marlvel.ai/apps/th-co-mtel-muslimdailythai) | N/A/5 | N/A | Mudarmeen Munlin | | [108 Divyadesam Navigator](https://marlvel.ai/apps/com-rsunda12-divyadesams) | N/A/5 | N/A | Rajagopal Sundarrajan | | [1Call Taxi](https://marlvel.ai/apps/1call-taxi) | 5.0/5 | N/A | Ardalan Hussein | | [1st Central Connect](https://marlvel.ai/apps/1st-central-connect) | 3.0/5 | N/A | Cambridge Mobile Telematics Inc. | | [24Seven Taxi Driver](https://marlvel.ai/apps/24seven-taxi-driver) | 5.0/5 | N/A | 24Seven Taxi Dispatch, LLC | ## Company Profile - **Developer:** GUIDELING OU ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/istanbul-guide-tours/id1469729221?uo=4) - **Sources:** App store metadata. ## Related Intel Reports - [*กิจวัตรมุสลิมไทย*](https://marlvel.ai/apps/th-co-mtel-muslimdailythai) (Mudarmeen Munlin) · N/A Rating - [*108 Divyadesam Navigator*](https://marlvel.ai/apps/com-rsunda12-divyadesams) (Rajagopal Sundarrajan) · N/A Rating - [*1Call Taxi*](https://marlvel.ai/apps/1call-taxi) (Ardalan Hussein) · 5.0/5 Rating - [*1st Central Connect*](https://marlvel.ai/apps/1st-central-connect) (Cambridge Mobile Telematics Inc.) · 3.0/5 Rating - [*24Seven Taxi Driver*](https://marlvel.ai/apps/24seven-taxi-driver) (24Seven Taxi Dispatch, LLC) · 5.0/5 Rating - [*24Seven Taxi Service*](https://marlvel.ai/apps/24seven-taxi-service) (My Taxi Ride Inc.) · N/A Rating - [*2 one day trips Tokyo suburbs*](https://marlvel.ai/apps/2-one-day-trips-tokyo-suburbs) (mlet co.,ltd) · N/A Rating - [*360 Central Park AR NYC Map*](https://marlvel.ai/apps/com-vues-360centralpark) (Vadym Ustymenko) · N/A Rating - [*360 LA Los Angeles AR Map*](https://marlvel.ai/apps/360-la-los-angeles-ar-map) (Vadym Ustymenko) · 5.0/5 Rating - [*360 NYC: New York City AR Map*](https://marlvel.ai/apps/com-vues-360nyc) (Vadym Ustymenko) · 4.0/5 Rating ## Frequently Asked Questions {#faq} ### Does Istanbul Guide & Tours work without an internet connection?
