OPEN NOW
GHOST NOTE
A theremin on your wrist.
- OPEN NOW
- version 1.0 (6)
- join by Jan 9, 2027
- 99 of 100 seats left
Want to hear what the ghosts are rehearsing? Sing with them, free on TestFlight.
We'd love to hear:
- Can you sing a ghost's tune back on the Watch, or is tilt-to-pitch too twitchy?
- Does a note ever keep sounding after you lift your finger?
- On iPhone Duo: lay it flat, then half open it. Does the graveyard fill the screen with nothing cut off?
WAYPOINT
A tiny hiking game you steer with your own body.
- OPEN NOW
- version 1.0 (9)
- join by Jan 11, 2027
- 99 of 100 seats left
Want to hike a trail with your wrist? Waypoint is free on TestFlight: turn to aim, step, and reach the summit.
We'd love to hear:
- Hike one trail with sound on: does any sound feel too loud, too often, or wrong for what you did?
- Check that the hiker faces where the top of your phone points.
- On iPhone Duo: does Waypoint fill every screen, and does the compass follow when it turns?
LIGHTHOUSE
Keep the light for one night.
- OPEN NOW
- version 1.0 (2)
- join by Jan 22, 2027
- 100 of 100 seats left
Want to keep the light for a night? Lighthouse is free on TestFlight: turn your wrist, hold the beam on a ship, and bring it home.
We'd love to hear:
- Hold the beam on a ship: does about a second and a half feel right, or does it drag or slip away?
- Play a whole night, about two and a half minutes: does the pace hold, from the first ship through the fog and the squall?
- Let a ship run aground on the Watch: does the wreck plate cover the lubber triangle too long to steer by?
THAW
Write a note.
- OPEN NOW
- version 1.0 (5)
- join by Jan 24, 2027
- 100 of 100 seats left
Want to thaw a note? Thaw is free on TestFlight: write up to 140 characters, freeze them under frost or leaves, and warm the glass with a thumb until the words come through.
We'd love to hear:
- Did your thumb feel like it was melting the ice?
- When you sent a note to a friend, did it open on their phone, still frozen?
- On the Duo, does the open layout use both halves well?
FREETAIL
Fly a Mexican free-tailed bat through the dark, by sound and touch.
- OPEN NOW
- version 1.0 (9)
- join by Jan 11, 2027
- 99 of 100 seats left
Want to fly under the Congress Avenue Bridge? Freetail is free on TestFlight: chirp, listen, and dive.
We'd love to hear:
- Fly as deep as you can and tell us where the cave feels unfair.
- On Apple Watch: do the words deep in the cave ever sit on top of your landing depth?
- On iPhone Duo: does Freetail fill the whole screen?
FLOATING INK
Suminagashi, the old Japanese art of floating ink.
- OPEN NOW
- version 1.1 (7)
- join by Jan 15, 2027
- 100 seats
Drop ink on water and lift a print. Floating Ink is free on TestFlight.
We'd love to hear:
- Lift a few prints, then open Your prints: a shelf of washi-paper prints with albums. Make an album, and hold its tab to rename or delete it. Does anything feel fiddly?
- Add the “A print” widget to your Home Screen. It shows one of your prints on lacquer. Does it look like the print you made?
- On iPad, try Apple Pencil: pressure sets the size of a drop and how hard the comb and fan push, and tilt leans the comb’s teeth. Too light, too heavy, or just right?
- On Apple Watch, tap the tool button under the dish a few times. Does each tap move to the next tool: Touch, Bamboo comb, Fan, then Touch again?
CANDY CRAWL
A haunted hedge maze on your wrist.
- OPEN NOW
- version 1.0 (6)
- join by Jan 11, 2027
- 99 of 100 seats left
Walk the haunted hedge maze one step at a time. Candy Crawl is free on TestFlight, now with sound.
We'd love to hear:
- Play one maze with sound on: is any sound too loud, too busy, or confusing?
- Clear a maze and look at the shape it makes. Did you guess it before the reveal?
- On iPhone Duo: half open the phone. Does anything go black or get cut off?
MECHANICAL BESTIARY
A pop-up book of mechanical insects.
- OPEN NOW
- version 0.1 (33)
- join by Jan 12, 2027
- 98 of 100 seats left
Build the book before it's finished. Print a creature from inside the app, fold it, and tell us how to make the instructions better. The Mechanical Bestiary is free on TestFlight.
We'd love to hear:
- In the app, turn to any creature, tap the gear (Show folds and joints), then Print this insect. Print at Actual Size: the bar on the first page must measure 50 mm.
- These prototype patterns have not yet been assembled and tested by hand, and the Cricut files (Save Cricut files, on the same page) have not been cut on a real machine. If you build one, send photos with the book at 0°, 90° and 180° to studio@releaf.site, and tell us which step was unclear or which piece didn't fit.
- Does your paper creature move the way the one in the app does?
TACHLINE
Keep the marble on pace.
- OPEN NOW
- version 1.0 (23)
- join by Jan 19, 2027
- 73 of 100 seats left
Think you can keep a marble on pace? Tachline is free on TestFlight on iPhone and Apple Watch.
We'd love to hear:
- Does the new name read well on the title screen and under the icon?
- Add the Today's circuit widget: does it show a circuit and open the game?
- On Apple Watch: are the corner buttons fully visible on your model, and does the Crown roll the marble the way you expect?
HOW A BETA WORKS
Get TestFlight
It's Apple's free app for trying apps before release. Install it once from the App Store.
Tap a link above
Each open beta takes up to 100 testers. The app installs like any other and updates itself when we ship a new build.
Tell us what you found
In TestFlight, open the app's page and tap Send Beta Feedback, or take a screenshot in the app and share it to TestFlight. Every note is read, and the fixes go into the next build.
A build stops working 90 days after we upload it, so each invitation shows its last day. When an app reaches the App Store, its beta stays open for the next version.
Updated October 31, 2026.
Testers hear the choir first.
