A calendar and a task list are both buildable on their own. Motion's actual product is an algorithm that automatically re-slots your tasks around meetings all day, every time something changes — genuine scheduling-optimization research, not a feature.
VIBE SCORE 86/100
A moderate score above just means the individual parts are buildable — it isn't a build/buy recommendation on its own. Here's the actual reason this one's still JUST PAY:
The parts this build actually needs, each rated on its own — the average is the Vibe Score above.
| Landing page | 99 |
| CRUD database | 95 |
| User login | 92 |
| Complex calendar sync | 58 |
Two real costs, not just "free": the AI agent's own usage, and hosting once it's running. Both are estimated from this app's own effort rating and component list — see the assumptions on the method page.
| AI agent — with a subscription (Claude Pro/Max, Cursor, etc.) | $0 marginal |
| AI agent — pay-per-use API, no subscription | $86–$172 one-time |
| Hosting, once it's running | $0/mo (free tier) |
| Domain name, if you want your own | ~$12/yr |
Motion costs $34/mo. Even paying per-token with no subscription, and accounting for hosting, this build pays for itself in about 6 months.

Motion costs $34/mo (about $408/yr) as of 2026-08. That's what a working rebuild would save you.
Automatically re-optimizing your entire day's task schedule every time a meeting is added, cancelled, or runs long is a real constraint-satisfaction/scheduling-algorithm problem, not a calendar feature Balancing task priority, deadlines, and estimated duration into one optimal schedule, continuously, is applied operations-research territory Getting the auto-scheduling wrong in an annoying way (constantly reshuffling your day) is worse than not having it — this is a case where the hard part is also the point
