When I Work vs Zelt
A side-by-side editorial comparison of When I Work and Zelt — release velocity, themes, recent moves, and the top alternatives to consider.
When I Work vs Zelt: at a glance
What is When I Work?
When I Work pushes break compliance, mobile widgets, and richer schedule views — quarterly cadence on the help portal.
When I Work's captured feed mixes help-portal pages with quarterly release-note recaps. The substantive product moves visible: Break Attestation in Q1 2025 (clock-out prompts to record whether breaks were taken, with reasons if not), an iOS Widget surfacing 'Next Shift' to the home screen, broader Scheduling Breaks rollout in Q2 2025 across all plan types, an updated mobile clock-in UI, and an enhanced Schedule Views capability pairing a position view with a new coverage view to see who's working and where gaps exist.
What is Zelt?
Zelt's tracked feed is its UK HR/payroll content blog, not a product changelog.
Every entry is SEO/content-marketing from Zelt's blog — a paternity-pay calculator, payroll-feature listicles, 'best HR software 2026' roundups, HMRC-compliance explainers, an HRIS checklist. None are product releases, so the feed shows Zelt's content strategy (UK HR, payroll, and compliance keywords) rather than what is shipping in the product. That content is tightly themed around UK payroll and HMRC compliance.

◆ Current state
When I Work's captured feed mixes help-portal pages with quarterly release-note recaps. The substantive product moves visible: Break Attestation in Q1 2025 (clock-out prompts to record whether breaks were taken, with reasons if not), an iOS Widget surfacing 'Next Shift' to the home screen, broader Scheduling Breaks rollout in Q2 2025 across all plan types, an updated mobile clock-in UI, and an enhanced Schedule Views capability pairing a position view with a new coverage view to see who's working and where gaps exist.
◆ Where it's heading
Investment is concentrated on operator scheduling depth (position vs. coverage views), compliance hooks for jurisdictions requiring break tracking, and mobile-first usability. The cadence reads as quarterly batched release notes rather than continuous shipping — appropriate for the workforce-scheduling category but slower than SaaS norm.
◆ Prediction
Expect more compliance modules tied to predictive scheduling and fair-workweek rules, additional widget surfaces (Android widget, watchOS), and continued coverage-view evolution as the default manager-centric scheduling lens.

5.0HR
Zelt's tracked feed is its UK HR/payroll content blog, not a product changelog.
◆ Current state
Every entry is SEO/content-marketing from Zelt's blog — a paternity-pay calculator, payroll-feature listicles, 'best HR software 2026' roundups, HMRC-compliance explainers, an HRIS checklist. None are product releases, so the feed shows Zelt's content strategy (UK HR, payroll, and compliance keywords) rather than what is shipping in the product. That content is tightly themed around UK payroll and HMRC compliance.
◆ Where it's heading
On content alone, Zelt is targeting UK small-business HR and payroll buyers through compliance- and comparison-led SEO. Whether the product is moving in any direction can't be read here, because the crawler is pointed at the marketing blog rather than a release log.
◆ Prediction
The blog will keep producing UK payroll and compliance content. No product prediction is supportable from this feed; the crawl source should be repointed at a changelog to get real release signal.
