Key takeaways for Calculator +
Where is it heading?
The utility market is consolidating around high-precision tools that offer seamless workspace integration, leaving Calculator + exposed due to its recent feature-removal cycle. Unless the team restores core workflow features like the running total, the app will continue to lose its technical user base to competitors that prioritize consistent utility over aggressive monetization.
- The removal of the running total display disrupts long-sequence workflows, which directly increases churn among the app's most active power users.
- Aggressive subscription gating of previously free tools has triggered a cluster of negative reviews, eroding the app's long-standing positive sentiment.
The SWOT
- High-precision math capabilities function as a barrier to entry for casual calculator apps.
- Adding cloud-sync for calculation history would address the #2 top user request.
Next best moves
Restore the running total display because it is the top-requested feature to reduce churn → improve retention.

Integrated notes and drawing tabs (available in Calculator for iPad! but absent here). +1
Since the last report: The app's competitive position has declined due to user backlash against feature removals and monetization shifts, forcing a pivot toward stabilizing core workflows.
Bottom line
Calculator + maintains a strong utility core but risks its user base by gating legacy features behind subscriptions, so the PM must prioritize restoring the running total display to stabilize retention before further monetization experiments.
