Key takeaways for TIER – Unlock your city
Where is it heading?
The micromobility market is consolidating around multi-modal platforms, leaving standalone apps like TIER exposed to churn. TIER's pivot to Dott is a survival mechanism, but the execution friction threatens to accelerate the loss of market share to rivals like Bolt.
- Forced migration to a secondary app creates significant friction, which erodes the daily active habit for loyal users.
- Inconsistent parking zone detection leads to failed ride attempts, which compounds the negative sentiment from the migration process.
The SWOT
- In-house maintenance management across 400 cities
- Stable scooter hardware for daily commuting
- Consolidated infrastructure reduces operational overhead
Next best moves
Audit migration support flows because user frustration with app-switching is the top complaint -> reduce churn.

The forced migration is not just a technical necessity…
Read the full takeFeature gaps
Multi-modal super-app integration (available in Bolt but absent here) +1
Since the last report: The TIER application has formalized its sunset strategy, shifting from maintenance to a full decommissioning mandate while expanding its target audience to include the Middle East. This transition is further complicated by emerging user complaints regarding vehicle availability and failed unlock attempts.
Bottom line
The transition to Dott prioritizes operational efficiency over user continuity, creating a churn risk that outweighs the benefits of platform consolidation. Addressing the friction in the migration flow would stabilize the remaining user base before further attrition occurs.
