AI-Powered Analysis

Personalized insights generated by our AI

Tuta: Secure Private Calendar has excellent keyword visibility (7/10 top positions) and a solid quality score (88%), but it lacks chart presence and category ranking, limiting organic discovery.

High Keyword Rankings
high

7 of the top 10 target keywords rank in the top 3 (e.g., "tuta" rank 2, "secure calendar" rank 2, "encrypted events" rank 2). This drives strong search traffic (traffic scores up to 80) and should be maintained.

No Chart Presence
high

Charts Score is 0%, meaning the app is not appearing in the Top 200 installs for its category or globally. Without chart visibility, organic install volume is severely limited.

Unranked Core Keywords
medium

Important generic terms like "calendar app" (traffic 60) and "private planner" (traffic 50) are not ranked at all, leaving a sizable search demand untapped.

Category Ranking Gap
high

The app is not ranked in the Productivity category. Achieving a category rank would improve discoverability and eligibility for featured placements. Leveraging its high quality score (88%) can accelerate this.

Competitor Keyword Overlap
medium

Proton Calendar shares 5 high‑traffic keywords and currently outranks Tuta on some of them. By refining metadata (title, short description) to include exact matches like "encrypted calendar" and "private calendar", Tuta can reclaim those positions.

Key Action Items
Priority actions to improve your app's visibility
  • 1Launch a focused install campaign (e.g., Google UAC) to push the app into the Top 200 installs and generate a Chart Score.
  • 2Rewrite the title and short description to embed the highest‑traffic unranked keywords (e.g., "Private Calendar" and "Calendar App") while preserving brand identity.
  • 3Create localized store listings for English, German, French, and Spanish markets, incorporating local keyword variations and culturally relevant screenshots.
  • 4Refresh visual assets: add a feature‑highlight video and screenshots that showcase quantum‑safe encryption, dark mode, and Tuta Mail integration.
  • 5Implement an in‑app prompt to encourage 5‑star reviews after a successful event creation, aiming to increase the review count and maintain the 4.4‑star rating.
