Відомості Slackline.Ova
an offline slackline map with ISA safety reference and calculators
Slackline.Ova is an offline-first companion for slackliners: a worldwide map of lines with anchors, heights, access notes and parking, plus ISA safety reference cards, force calculators, a per-line rigger checklist and a gear catalogue with ISA warnings. All of it works without signal — which is usually exactly where you need it.
It started in Ostrava, an industrial corner of Czechia with one single highline that they keep kicking us off. These days it covers lines worldwide — data from slack.cz and Slackmap, gear from SlackData, all bundled for offline use.
Free, open source, no ads, no analytics, no tracking — and no account needed to use it. If the app helps you in the field, a coffee covers the store fees — Google Play ($25, already paid) and the Apple Developer Program ($99/year, not paid yet). Everything stays free and open source on GitHub.
