Key takeaways for Elek: Spam Call & SMS Blocker
Where is it heading?
The SMS filtering market is consolidating around automated, cloud-backed solutions that require zero user configuration. Elek's maintenance-mode update cadence and reliance on manual rules leave it exposed to churn as users migrate to more effective, automated alternatives.
- Persistent filtering failures in the latest release erode the daily active habit, which compounds the rating drag already visible on the platform.
The SWOT
- On-device processing ensures SMS data never leaves the user's possession.
- Integrating pre-built, community-sourced block lists could reduce the manual burden on users.
Next best moves
Pivot filtering logic to include community-sourced block lists because manual rules are failing to stop spam → increase user retention.

The app's privacy-first, on-device architecture is a liability rather than a strength…
Read the full takeSince the last report: The app's outlook has declined as the reliance on manual filtering rules is increasingly viewed as a competitive liability against automated, cloud-backed alternatives.
Bottom line
Elek offers a privacy-first value proposition, but the failure of its filtering logic to stop common spam messages undermines its utility, so the team must prioritize automated block-list integration to remain competitive against cloud-based rivals.
