Klacks vs When I Work

Klacks has no write-up on Specifiction yet; its figures are above.

When I Work brings employee scheduling, shift swaps, team messaging, and time tracking together for shift-based workplaces. Auto scheduling assigns shifts using staff availability and qualifications, and managers can oversee multiple stores, departments, or job sites from one dashboard. The time clock tracks attendance, breaks, and time off, while staff can message without sharing phone numbers. It runs on the web, Android, and iOS. Essentials costs $2.50 a month billed per user per month; Pro is $5 a month billed per user per month; Premium is $8 a month billed per user per month. A 14-day trial offers complete access and requires no credit card, but there is no free plan. API key access, webhooks, and SAML/SSO are included in Premium. When I Work says it uses AWS, TLS, daily backups, multiple-disk writes, and mobile two-step verification. It does not offer an SLA, although its hosting partners guarantee 99.9% uptime.
