It records the jump.
You write the story.
A paired sensor catches exit, freefall, deploy, and landing within 200 ms. Every auto-filled field wears an auto badge — tap to override and it's yours.
How detection works →It records exit, freefall, and landing on its own — then keeps your logbook, your gear, and your license progress in one place. A reference tool for jumpers, not a safety device.
We invite in waves. We'll write when there's a spot — no countdowns, no spam.
No feed, no streaks, no badges to chase. It does the record-keeping a serious jumper actually has to do — and gets out of the way.
A paired sensor catches exit, freefall, deploy, and landing within 200 ms. Every auto-filled field wears an auto badge — tap to override and it's yours.
How detection works →Track A–D categories against USPA, BPA, or FAI requirements. Hand an instructor a digitally-signed snapshot that holds up in a regulatory audit.
Multi-authority progress →Repack countdowns, AAD service dates, and jumps-on-canopy — tracked per rig. Riggers you've linked update the ledger; you both see the same record.
Gear lifecycle →The classifier reads barometric and inertial data and labels each phase as it happens — exit, freefall, deployment, canopy, landing. Specific, not magic: it's measured against a hand-labeled library of real jumps, and it tells you when it isn't sure.
Compliant logbook exports formatted for
Authority marks shown as text pending each body's brand-use approval. We never imply endorsement we don't have.
SkydiveZero won't save your life and we won't pretend it can. It keeps records, surfaces what your gear needs, and stays out of your decisions in the air. No ads. No data sale. Full export and account deletion, any time.
SkydiveZero is a small independent team of skydivers who got tired of paper logbooks and spreadsheets. No VC funding, no growth hacking — just a tool we wanted to exist.
We're building in public and inviting the community in early. Your feedback during beta shapes what ships. The codebase runs on Cloudflare, the app ships on iOS and Android, and everything you log is yours to export or delete.
During beta, auto-recording requires a paired Bluetooth sensor (a compatible altimeter or watch). Manual logging works without any hardware — just your phone.
USPA, BPA, FAI, FFP, DAeC, and KNVvL at launch. We format logbook exports to each body's current requirements. More authorities are planned.
No. SkydiveZero is a logbook and reference tool. It records what happened; it does not intervene during a jump. We say this clearly in the app and everywhere else.
Free tier covers full logbook functionality. Pro adds gear lifecycle, multi-rig tracking, and priority beta access. See the pricing page for details.
You can export everything as JSON or CSV and delete your account at any time. We use Cloudflare Web Analytics only — no third-party tracking SDKs.
We're in invite-wave beta now. Join the list and we'll email when there's a spot — no fake countdowns.
One field, one role. We invite in waves and write when there's a spot. The first 50 Layer 1 contributors keep Pro for life.
No countdowns. No "limited time." We'll only email about your spot.
