(Strategic Takeaway) {#so-what} TIER – Unlock your city is a travel app that is free with in-app purchases. With a 4.71/5 rating from 3.5K reviews, it shows mixed user reception. > **Bottom Line:** The transition to Dott is a necessary consolidation, but the friction of forced migration risks ceding the user base to Bolt. Prioritizing a seamless account-transfer flow will determine whether TIER's legacy riders convert to Dott or churn to rivals. **Best for:** Urban commuters and city residents seeking short-distance, pollution-free transportation alternatives. ### PM Action Plan (Next Best Moves) - [ ] [SUNSET] Sunset the TIER application entirely because the migration to Dott is complete → eliminate support costs ### Feature Gaps vs Competitors - Unified super-app interface (available in Bolt but absent here) ### Outlook: Declining The micromobility market is consolidating, and TIER's exit as a standalone brand reflects the broader pressure to achieve scale through unified platforms. The immediate so-what for the developer is the risk of losing the legacy user base during the transition, which Bolt is positioned to capture. - 🔴 The mandatory migration to Dott creates a high-friction barrier, which directly accelerates user churn toward competitors like Bolt. - ⚪ The lack of independent release activity confirms the developer has effectively sunsetted the TIER brand in favor of Dott. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.71/5 | | Total Reviews | 3.5K | | Sentiment | Mixed (55/100) | | Confidence | High | | Pricing Model | Freemium | | Platforms | iOS | | Key Features | 2 analyzed | | Trend | Declining | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **TIER – Unlock your city** (this app) | 4.71/5 | Mixed | Tier Mobility GmbH | | [Citymapper: All Live Transit](https://marlvel.ai/apps/azdev-citymapper) | 4.9/5 | Thrilled | Citymapper Limited | | [Freenow by Lyft - taxi & more](https://marlvel.ai/apps/de-intelligentapps-ott-client) | 4.8/5 | n/a | Intelligent Apps GmbH | | [Bird — Ride Electric](https://marlvel.ai/apps/bird-ride-electric) | 4.9/5 | n/a | Blue Jay Transit Inc. | | [Voi – e-scooters & e-bikes](https://marlvel.ai/apps/voi-e-scooters-e-bikes) | 4.9/5 | n/a | VOI Technology AB | | [Bolt: Request a Ride](https://marlvel.ai/apps/bolt-request-a-ride-1) | 4.8/5 | Excited | Bolt Technology | ## Company Profile - **Developer:** Tier Mobility GmbH - **Website:** [https://www.tier.app](https://www.tier.app) - **Social:** [Instagram](https://www.instagram.com/ridedott) · [Facebook](https://www.facebook.com/ridedott) · [X/Twitter](https://twitter.com/Dott) · [YouTube](https://www.youtube.com/@ridedott) · [LinkedIn](https://www.linkedin.com/company/ridedott) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/tier-unlock-your-city/id1436140272?uo=4) - **Dev Site:** [Official Website](https://www.tier.app) - **Sources:** Developer website content, About us / company information, App store metadata, User reviews. ## Related Intel Reports - [*Citymapper: All Live Transit*](https://marlvel.ai/apps/azdev-citymapper) (Citymapper Limited) · 4.9/5 Rating | Excellent Sentiment - [*Freenow by Lyft - taxi & more*](https://marlvel.ai/apps/de-intelligentapps-ott-client) (Intelligent Apps GmbH) · 4.8/5 Rating - [*Bird — Ride Electric*](https://marlvel.ai/apps/bird-ride-electric) (Blue Jay Transit Inc.) · 4.9/5 Rating - [*Voi – e-scooters & e-bikes*](https://marlvel.ai/apps/voi-e-scooters-e-bikes) (VOI Technology AB) · 4.9/5 Rating - [*Bolt: Request a Ride*](https://marlvel.ai/apps/bolt-request-a-ride-1) (Bolt Technology) · 4.8/5 Rating | Positive Sentiment - [*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 ## Frequently Asked Questions {#faq} ### Can I still use the TIER app to rent scooters?
