Pricing entry tiers: Apollo Enrichment at Custom, Outlook Calendar at From $5/mo. Check each app's tier structure for the capacity limits you actually need before deciding — the headline number is the same shape, but the gating shape per tier (seats, usage volume, integrations) varies.
Outlook Calendar has the larger user base (1,545 reviews vs 30), which usually maps to broader integration coverage, faster bug-fix cadence, and a deeper bench of community workflow patterns.
