Key takeaways for TIER – Unlock your city

Where is it heading?

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.

Feature gaps

Unified super-app interface (available in Bolt but absent here)

Since the last report: TIER has moved from a maintenance-mode app to a fully sunsetted service, with the PM action plan now prioritizing total decommissioning to eliminate support overhead. This shift is compounded by new user reports of parking zone detection failures, further eroding the experience for remaining legacy users.

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.
