DeskTime

Pros

• Tracking runs automatically in the background, so staff do not have to start or stop timers, which reviewers on G2 cite most often.
• ISO 27001 and ISO 27701 certification, plus EU-based operation, helps buyers who must comply with GDPR.
• Project time tracking calculates costs from hourly rates, which helps agencies bill clients.
• Premium combines shift scheduling and an absence calendar with time tracking, so these do not need a separate tool.
• Per-user pricing starts at about 6.42 USD a month on annual billing, which is low for this category.

Cons

• Reviewers describe the URL tracking and screenshots as intrusive, and these features may need a legal basis in some jurisdictions.
• Capterra and G2 users report instability, such as tracking stopping or activity being marked as neutral.
• It has no Kanban boards, Gantt charts or task management of its own, so it depends on tools like Jira, Asana or Trello.
• Reviewers say time spent in meetings and offline work are tracked poorly.
• Screenshots and the API are only on Premium.

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.
