Pronounced “parks.” A day worth keeping.

A park day to keep

Keep your park day.

PRKS is being built to turn your park day into a record of rides, estimated waits, walks, and a map to keep.

Real recording · 26 Sep 2026

A small walk. A real beginning.

Crocker Park, Ohio · PRKS walking test. Corrected GPS trail; no basemap. Gaps stay visible.

Not a theme-park ride test.

How it works · the plan

Enjoy the day. Keep the story.

From your first steps to the walk out, a record that starts with where you actually went.

01 / Record

Start your park day.

Start recording on your iPhone. PRKS captures location in the background with your permission.

App screenshot — later

02 / Understand

Rides. Waits. Walks.

After upload, PRKS estimates the parts of your day. GPS has limits; estimates should say so.

03 / Keep

Make your mark.

Your day’s trail becomes a map to revisit. A shareable souvenir—the “mark”—is planned.

Built for enthusiasts

Remember more than your last ride.

The rerides. The long walk across the park. The queue that felt shorter than expected. We’re building for the details you want to revisit.

  • Your ride historyA day’s rides, in context.
  • Estimated waitsWith posted waits where available.
  • Walking distanceFrom the corrected recorded trail.
In development; accuracy is still being tested.

Synthetic example · Cedar Point

A whole day has a shape.

Generated test fixes, processed by the classifier. Not a real guest’s day. Lines = trail; diamonds = stays.

Privacy, plainly

Your location deserves an explanation.

Recording a day uses precise location, including in the background. Captured points are uploaded to PRKS’s server to work out the day’s rides, waits, and walks.

Joining this waitlist asks for your email, not your location. Your home park is optional. Beta invitations are a separate choice.

A few good questions

Before your next visit.

Can I download PRKS yet?

PRKS is in development for iPhone. Join the waitlist for updates; beta opt-in lets us know you’re interested in testing. It doesn’t guarantee an invitation.

Which parks will it support?

Testing starts with Cedar Point. More parks are a possibility, not a promise. The optional home-park field helps us understand where people go.

Will every ride and wait be exact?

No. GPS and the classifier have limits. Ride detection, waits, and distance are estimates, and accuracy is still being tested.

Does the app need location access?

Yes. A recorded park day uses precise location, including background access. Joining the email waitlist needs no location permission.

What does joining the waitlist mean?

You consent to PRKS development and launch emails. Beta invitations are optional. You can unsubscribe from emails at any time.

Is the shareable mark available?

Not yet. The share card is planned. The trail drawings on this page are design previews, not app screenshots.
