Honest, fairly priced apps for Jira Cloud

Every app here runs on Atlassian's Forge platform, is priced for the people who actually use it, and matches or beats the incumbent it replaces on features.

AppWhat it does
Honest Timesheets for JiraWorklog grid, timers, approvals, team view and reports, bucketed in each author's own timezone.
Pivot Reports for JiraPivot tables and charts over any JQL, with drill-down, CSV and dashboard gadgets.
Tickbox Checklists for JiraRequired items, auto-applied templates, board progress, JQL fields and workflow gates.
Mailpost for JiraEmail an issue from Jira with templates, recipients from the issue and a send log.
Agile Gadgets for JiraTwenty dashboard gadgets — burndown, velocity, cumulative flow, cycle time, time in status, aging WIP, throughput, pivots, KPI gauges, a team board and a TV wallboard — rebuilt from issue history.
Stencil Issue Templates for JiraIssue templates with whole epic → story → sub-task trees, placeholders and prompted variables, applied wherever work items are actually created.
Git Links for JiraCommits, branches and pull requests on the issue for GitHub, GitLab, Bitbucket and Azure DevOps.
Status Clock: Time in Status & SLA for JiraTime in every status on a working calendar that gets weekends, holidays and daylight saving right, plus a real SLA engine with pause, breach detection and JQL search.
Ditto: Bulk & Deep Clone for JiraDeep clone a work item with everything under it, or bulk clone a whole search — including between team-managed and company-managed projects, which nothing else in the category does. Attachments, links and field mapping by name, with an honest report of whatever will not fit.
Countersign: Approvals & Sign-off for JiraMulti-stage and parallel approvals with quorum rules, delegation and escalation, enforced by a real workflow validator, with a tamper-evident audit trail you can export and verify.
Slide Rule: Calculated Fields for JiraCustom fields that compute themselves from a real formula language — arithmetic, conditionals, dates and rollups over children, the parent and linked work items. The value is written into Jira's own index, so it is right on board cards, in JQL and in exports, not only on the work item.
