Finally amsaw I this week, it’s free and it’s awesome. This really highlights what a jungle of mostly junk the AppStore is. I wish there was something Apple could do to improve it. Download this game. No ads either!! ### 5/5 — Excellent jeux *2022-01-11, version 1.1.2* Relax et amusant ### 5/5 — This game is really fun *2021-06-28, version 1.1.2* I love this game because it’s like a mind trick almost but not exactly it’s really fun now but as a child I don’t have any money so I think it should be free for all ages but this app is so amazing ### 5/5 — Great Game! *2021-04-06, version 1.1.2* This game is very fun. It can be difficult but that’s kinda the point. ### 5/5 — Very nice music! *2021-02-02, version 1.1.2* This game has the music I’ve heard in a game in a while. A lot of games like Minecraft and Terraria are known for having very unique music. Kerflux has music just as good or even better! ### 5/5 — Just the right balance of challenge, chill, and unfocused focus *2020-09-19, version 1.1.2* This game is great when my mind is busy but I’m too tired to think. Gameplay is so simple that instructions would get in the way, but that doesn’t mean the game is easy. It takes the kind of immersive tuning-in that shoves busy, random thoughts to the side. The way the audio adapts to the wave adjustments is a delightful feature. This is an ideal game for anxious nerds! ### 5/5 — Solid game from a while ago! *2020-09-17, version 1.1.2* Hasn’t been updated in 4 years and still holds up!! ### 5/5 — Try it ! *2020-08-06, version 1.1.2* A wonderfully absorbing game: it tests your spatial intelligence and focus! And, last but not least, addictive! ### 5/5 — Great Game *2020-06-14, version 1.1.2* I’m glad they didn’t charge you for the game and instead added a “pay what you want” feature. However, if it was a game I had to pay for, I would have just because of how great the game is. I feel like the creators were not in it to make money, but instead they were in it because they had passion and a very interesting concept that teaches you something in the process, well done. ### 5/5 — Loving this game *2020-06-03* Really enjoying the clean visual design and puzzle concept, and I love how the music subtlety reacts to sliding the waves ### 5/5 — Nice game for both sides of brain *2020-05-13, version 1.1.2* Worth it ### 5/5 — Someone wrote my review for me *2020-05-03, version 1.1.2* The title was, “Fourier Analysis: The Game” It’s a good game. ### 5/5 — Great *2020-04-17, version 1.1.2* Confusing to explain but very good ### 5/5 — Really interesting *2020-04-02, version 1.1.2* Different abstract puzzles. Enjoyable. 👍🏻 ### 5/5 — Круто! *2020-03-28, version 1.1.2* Очень интересная игра. Не видела ничего подобного ранее. Очень советую! ### 5/5 — Calming and fun *2019-12-25, version 1.1.2* Great game! ## Most critical reviews (10 lowest-rated) ### 2/5 — Неплохо *2016-10-08, version 1.1.2* Прикольненько ### 3/5 — i like and hard *2020-11-28, version 1.1.2* i mean i like it but i haveing my head a brain cramp ### 3/5 — It’s mindless but entertaining so far *2019-05-19, version 1.1.2* Hoping the levels will become more challenging! ### 3/5 — suggestion *2017-05-26, version 1.1.2* it is a good fun and it would just better if the sound of every wave would be different from another ### 3/5 — Good I guess *2017-05-07, version 1.1.2* It's a good game and extremely addictive. The only thing wrong with this game is that the music won't work:-; ### 4/5 — Almost Excellent *2021-01-13, version 1.1.2* Add capacity for multiple profiles and this will bump to five stars. ### 4/5 — Good stuff. *2017-07-17, version 1.1.2* Would recommend. ### 4/5 — Fun *2017-04-25, version 1.1.2* See above ### 4/5 — Bonito! *2017-02-22, version 1.1.2* É uma delícia mover e buscar o encontro... ### 4/5 — Pretty Nice! *2017-02-20, version 1.1.2* It's a nice app, although I usually play it when I'm bored. It keeps my mind off other things and the music is unusually catchy! I just wish that it was a little more interesting, but so far it's a really nice app! ## Most praised reviews (10 highest-rated) ### 5/5 — Beautiful premise *2026-03-22, version 1.1.2* This is my new favorite game. Its puzzles are intriguing, challenging, and just plain brilliant. Those who are scientifically gifted will recognize these puzzles as Fourier constructions. Or deconstructions maybe. Either way it’s 100 percent entertainment and secretly educational simultaneously. ### 5/5 — Great Game! *2025-12-30, version 1.1.2* Simple to understand but a visual challenge. ### 5/5 — Great game *2025-10-30, version 1.1.2* Awesome game no ads Hope it remains the same ### 5/5 — Love this game, one of my favorites *2025-07-10, version 1.1.2* Now this is a game! This game is amazing! I love it…. ### 5/5 — I’d buy that for a dollar! *2025-06-25, version 1.1.2* And so I did. Really chill, neat concept where you just kinda figure it out with intuition. Only complaint is the difficulty plateaus so the endgame is very repetitive. One tip: when you get to the highest difficulty levels, use four fingers at a time and just kinda feel it out with each finger going at a different speed or direction. I’ve completed some levels before the waveform even loaded. Love the vibes here and appreciate the developer’s pricing model. I unlocked all achievements in like two sittings, if that’s your thing. ### 5/5 — Love this game *2024-04-02, version 1.1.2* This game is amazing! I love it ### 5/5 — Super Fun and Mathy! *2023-12-19, version 1.1.2* Reminds me of adding waves like sine and cosine from higher level math classes like Fourier Analysis!! No math required though lol! 😊😇 ### 5/5 — Great puzzle game *2023-12-10, version 1.1.2* Its a really fun way to pass the time and its pretty fun but it gets a little repetitive after pike level 200 because there isnt much to do, maybe it could introduce new mechanics when you get to higher levels to make it harder. Just a suggestion but this game is really fun i would recommend playing. ### 5/5 — just a real good time *2023-04-22, version 1.1.2* just download it, really fun ### 5/5 — Great to pass time *2023-04-07, version 1.1.2* I just got past the 700 level mark and I gotta say this is a great way to pass time. One thing I’d like is to be able to choose how many waves you have. And to add more than 4 waves to make it more challenging. I realize this game probably got it’s last update a while ago but I’ll keep playing from time to time.
