Is Google Calendar cheaper than ZoomInfo?

For most accounts under typical category usage, the answer depends on tier. Google Calendar is in the free band (Free), while ZoomInfo is paid (Paid). At parity scale, the cheaper option can save 30–60% — but feature-for-feature swaps usually narrow the gap above the second tier.

Why isn't every option on this list?

This page surfaces 12 alternatives ranked by blended score. Apps just outside the top-12 typically have lower feature similarity (under 40%), thinner listings (audit under 65), or have flagged review-quality issues. If you have a specific app in mind, check the full Slack catalog for its profile.

How is the ranking built?

Three signals, weighted: feature similarity (45%) from N-gram match against ZoomInfo's feature signature, audit + rating (35%) blending listing quality with rolling 90-day rating, and review velocity (20%) tracking 30-day review additions normalized by category baseline. We don't accept paid placement and we publish the rules so you can audit them yourself.

When was this ranking last updated?

This page rebuilds daily. Source data — ZoomInfo's listing and the 12 alternatives' listings — is scraped every 24 hours. Audit scores re-run on the same cadence. If a rating shifts more than 0.05★ overnight, that's a real change in the marketplace, not a model artifact.

Can I track ZoomInfo alongside its alternatives in AppRanks?

Yes — that's the dashboard product. Add up to 12 competitors to any app you track, and AppRanks will surface daily ranking deltas, ad activity, keyword overlap, and rating-curve divergence. The free tier covers 1 app + 3 competitors. Try free →
