Pros & Cons
Clockify
Pros
- The free tier gives unlimited time tracking with a timer, a timesheet, and desktop and mobile apps.
- Paid plans are inexpensive, from 4.99 to 14.99 USD per seat per month.
- A broad feature set covers kiosk clock-in, attendance, time off, invoicing, and expenses in one tool.
- Enterprise security includes SOC 2 Type II, ISO 27001, SSO, SCIM, and audit logs.
- Integrations shipped in 2026 include Jira two-way sync, Xero, and Peppol.
Cons
- Reviewers report that the mobile app syncs poorly with desktop and lags.
- Reports and dashboards are hard to customize, and the free plan limits reports to one month of data.
- Useful features such as approvals, invoicing, and scheduling sit behind paid tiers.
- It lacks project management basics such as kanban boards and docs, which require Plaky.
- In August 2026 a Serbian group entity was reported to be in liquidation, which raises vendor-stability questions.
Slack
Pros
- The app ecosystem is very large, and tools such as ClickUp, Notion, HubSpot and Clockify can post updates into channels.
- Slack Connect lets teams work in shared channels with up to 250 outside organizations on paid plans.
- Compliance coverage is broad, including ISO 27001, SOC 2 Type II, FedRAMP Moderate and HIPAA configurability.
- Lists add table and board layouts with assignees, due dates and subtasks, without leaving chat.
- Workflow Builder automates routine requests and approvals without code.
Cons
- There are no native Gantt charts, dependencies, time tracking or portfolio reporting, so Slack doesn't replace a dedicated PM tool.
- Frequent notifications and busy channels can interrupt focus, a common complaint in reviews.
- The free plan keeps only 90 days of message history and allows 10 apps.
- Advanced AI features require Business+ or above, and per-user costs add up as teams grow.
- Reviewers report that finding older messages through search can be difficult.
