Wavelength is the app version of the party board game of the same name. One player sees a hidden target on a spectrum (say, hot to cold) and gives a clue that fits that spot; everyone else turns a dial to where they think the clue lands. It's cooperative, so the whole group is trying to read one person's mind rather than beat each other. Games support 2 to 10 or more players, in one room or remotely, and it runs on most mobile platforms so mixed groups can join. Dials move in real time for everyone, emoji reactions add some noise, and the prompt library includes 390 spectrums not found in the physical box plus occasional themed packs. Avatars are customisable, and teams chase a shared high score with personal achievements alongside. It's free with no ads at all, which is rare for a party app.
Palm Court's app is a faithful version of the Wavelength board game. One player sees a hidden target's position along a scale, cold at one end and hot at the other, and offers a clue fitting that position. The rest of the group rotates a pointer toward wherever they believe the clue belongs. Everyone is cooperating to read one mind.
Groups from two up to ten or beyond can play, together or remotely, across the main mobile platforms. There are 390 spectrums not in the physical box, plus themed packs. It's free with no ads whatsoever, rated 9+, and scores 4.9 from more than 10,000 reviewers.
Someone becomes the psychic. They see the target on the spectrum and have to think of a clue that sits right there: for a spectrum running from underrated to overrated, perhaps a specific film. Everyone else sees only the spectrum and the clue, argues, and drags the dial. The reveal shows how close the group got, and the score climbs with every near-hit.
Dials move live on every screen, emoji reactions fly around, and the debate is where the fun lives. Remote groups play over a video call with the app handling the board; a room full of people passes the role of psychic around the circle.
Owners of the board game want a travel version and a way to play with friends in other cities. Everyone else finds it when searching for a party game that works over a call. The lack of adverts and the free price are rare enough in the category that they get mentioned in recommendations, and a 4.9 rating reinforces the word of mouth.
The dial is the centrepiece, a semicircular gauge that every player can turn, with the spectrum's two ends labelled and the clue displayed above. Customisable avatars and emoji reactions add some personality. Five screenshots are on the listing. Expect a clean, modern party-game look with large touch targets built for passing a phone around.
Palm Court LLC is the board game's own publisher bringing it to phones, which usually means the app is treated as part of the product line rather than a side project. Real-time multiplayer requires live servers. The 4.9 rating from over 10,000 reviews is excellent. Themed packs are mentioned but no update rhythm is given, and only the App Store is linked.
Remote game nights
Dials sync live, so a group on a video call plays as if they shared a table.
Mixed-device groups
Most mobile platforms are covered, so nobody is left out by their phone.
Cooperative players
Everyone wins or loses together, which suits groups who dislike cutthroat party games.
Rated 9+. Free with no ads, which the developer states outright. Themed packs are offered and may be paid, but the listing doesn't price them or describe other in-app purchases. Remote play needs a connection for every player; local play on one device is implied but not detailed.
Account requirements, storage size and regional availability aren't mentioned.
Our take
An easy recommendation for anyone who hosts game nights, in person or over a call, and especially for groups that already own the box. It's cooperative and conversational by design, so people who want a competitive scoreboard or a solo mode will find nothing here for them.
