Compare Swaymark and Exist by integrations, manual tracking, correlations, experiments, work context, privacy posture, and audience.

Updated 10 minute readBy Swaymark Editorial
Two personal analytics timelines comparing broad life correlations with focused health and work context

Exist and Swaymark share a useful premise: a signal becomes more informative when it can be compared with the rest of a person's life. Both support manual and connected context, patterns, and experiments. Their clearest difference is scope and intended audience.13

Exist is a broad personal analytics service with many kinds of integrations and user-defined tracking. Swaymark is a more focused personal observability product for indie developers and knowledge workers. This comparison relies on official product information and does not invent hands-on results.13

Swaymark vs Exist at a glance

Exist describes automatic tracking, custom tags, cross-domain correlations, trends, experiments, and weekly summaries. Swaymark records five daily signals and mood, adds permissioned Apple Health context, and can connect GitHub plus optional product-business sources before suggesting a bounded experiment.13

Choose Exist for breadth, customization, and data access

Exist's strongest case is its broad personal analytics model. Its official materials describe automatic data sources, manually tracked attributes and tags, correlations across categories, experiments, trends, and weekly summaries. That flexibility suits someone whose questions shift across fitness, sleep, mood, productivity, weather, and other domains.1

Exist's published values also make data export, API access, scoped integration permissions, and a single-plan business model part of the product philosophy. People building their own workflows or prioritizing data portability should examine those current capabilities closely.2

Choose Swaymark for a focused work and recovery loop

Swaymark narrows the problem around how a week felt and what moved with observable work. Its five daily signals cover Sleep, Move, Focus, Side project, and Nutrition. Mood check-ins, selected Apple Health imports, GitHub history, and optional PostHog, RevenueCat, Stripe, and X signals add context without requiring every connection.3

The intended output is a cautious weekly story, a small experiment, and useful observations saved to a Personal Playbook. That opinionated loop may be more approachable for an indie developer than a highly customizable analytics system. It is less suitable when you want the broadest possible integration catalog or custom attribute model.3

How should you interpret correlations in either app?

A correlation can surface a question, but it cannot establish why two signals moved together. The direction may be reversed, a third event may affect both, or the sample may overrepresent unusual weeks. Automatic data can also have device gaps, while manual entries may disappear precisely when life becomes difficult.

Prefer a narrow window and a reversible test. Record the hypothesis before changing anything, keep missing data missing, and look for counterexamples. Health and recovery outputs are context rather than medical advice. Seek professional care for persistent or concerning symptoms.
