The app has entered a terminal state, with the latest release serving as a migration notice to the Dott application. There has been no development activity or feature updates since September 2025. Given the current date of May 2026, the app has been silent for over 8 months, meeting the criteria for a zombie status.

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.
The SWOT
- Hardware reliability provided a stable ride experience for daily commuters
- Dott can capture TIER's legacy user base by streamlining account transfers
Next best moves
Sunset the TIER application entirely because the migration to Dott is complete → eliminate support costs

Read the full takeFeature 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.
