Full checklist on Pro, but no mobile app or extension. Why?
Scores come from public evidence (vendor pricing pages, help docs, feature pages), checked 2026-10-22. We have not run hands-on tests yet. They are planned, and these scores will be updated. See every source ↓
The fastest way to lose a warm lead is a week of “does Tuesday work?” emails. We score the plan a solo consultant can buy for $15 a month or less.
How this ranking was scored: desk research, version 1, checked 2026-10-22. We checked each tool against the public checklist below using vendor pricing pages, help-center docs and feature pages. Every point links to its source under “Why each tool scored what it did”. Plan scored: Best plan at or under $15/month that can take payment at booking (monthly list price; ties on the checklist go to the cheaper plan). One-time lifetime deals are not scored.
We have not run hands-on tests yet. They are planned with the fixture in tests/scheduling/scenario-01.md, and scores will be updated when they are done.
Why each tool scored what it did
Each Quality and Speed check is worth 2 points (2 = verified on the plan scored, 1 = limited, add-on, higher tier or conflicting docs, 0 = not available or not verifiable). Price bands, monthly list price: $0 = 10 · ≤$10 = 9 · ≤$15 = 8 · ≤$20 = 7 · ≤$25 = 6 · ≤$30 = 5 · ≤$40 = 4 · ≤$50 = 3 · ≤$75 = 2 · more = 1.
