The apps camera functions don’t work. Get a quick blip of camera view then nothing, it freezes. Updated app to try this. And sonar has never made sense. Just blobs across the screen. Clearly not random but doesn’t make any sense. Do I hold phone away, point flat, hold upright turn around, bottom, top, etc. would be nice to know what I need to do. What is it showing me? It would be nice if after starting the “experiment “ the graph had the option to scroll with the data on a fixed time window, not keep compressing the data. ### 2/5 — Units? *2026-01-06, version 1.2.0* What if we do not like meters? I gave you two stars because two years ago someone asked and you ignored this simple question/ask. ### 5/5 — Strangely entertaining *2025-12-26, version 1.2.0* Have you ever wanted to measure some of the most random things possible on your phone? Well your in luck, because this app essentially just gives you free range of your phone’s sensors, meaning you can just screw around on its magnetometer, or measure the speed of an elevator in one app! ### 5/5 — Absolutely amazing *2025-12-23, version 1.2.0* Extremely cool massive set of tools. I had no idea the capabilities of my.phones various sensors. ### 5/5 — App de malade *2025-11-26* Bonjours Mon Avis précédent a été censuré #onestenfranceou, ducoup je le réécris. Je connais cet app du à ma prof (big up),cet chose m’a fortement déçu elle est fonctionne mal sur les téléphone et elle est indisponible sur pc donc impossible de connaître les g qu’on prend sur gta ce qui est dommage (c fo) ce qui aurait permis à Lassalle de patient jusqu’à gta 6, la seul chose que cet app fait correctement, c’est de me torcher quand j’ai une diarrhée aiguë ### 5/5 — 老師好帥 *2025-11-17, version 1.2.0* 老師叫我下載的 ### 5/5 — Muito útil *2025-11-17* Excelente app para aulas de física. ### 5/5 — L’application ultime *2025-11-05* Tout d’abord, j’aimerais adresser mes remerciements les plus sincères à ma superbissime enseignante d’enseignement scientifique, pour avoir eu la présence d’esprit et la dévotion de m’avoir fait connaître cette merveilleuse application. Ses bienfaits médicaux permettent l’évacuation du stress et libère de l’emprise de la cocaïne. De plus, ses conseils culinaires m’ont fait redécouvrir mon chien Toby ( paix à son âme mais ça en valait la peine. ) Enfin, je m’agenouille face aux développeurs de cette application transcendant les limites humaines, qui ont des capacités divines et dont l’intelligence n’a d’égale que la grandeur d’âme pour nous avoir partagé cette infime partie de leur infini savoir. ### 5/5 — 민서 *2025-11-04* 사랑해 ### 5/5 — Appli très complète *2025-11-01* Appli très complète, permet de bien utiliser les capteurs du téléphone, seuls ou combinés. Très utile pour faire de petites expériences de physique chez soi, sans avoir de matériel spécifique. ### 2/5 — Bonne application *2025-10-17, version 1.2.0* Grâce a cette application recommandé pars Mme Pasquet j’ai eu 67cm en plus je joue en nba et t je suis le premier ministre lecornue ### 5/5 — Thank you Chris Boden *2025-10-10, version 1.2.0* Very Cool ### 5/5 — So awesome *2025-10-06, version 1.2.0* I don’t use this app enough, it’s truly underrated and fun to mess around with. ### 5/5 — Keep up the good work *2025-10-01, version 1.2.0* Absolutely loved the app, it has everything I could ever ask for ### 5/5 — 👍 *2025-09-25, version 1.2.0* Perfekt um eure Lehrer zu trollen. ### 5/5 — Chigga *2025-09-16, version 1.2.0* I died because of flashbang ### 5/5 — Gooood *2025-09-08* 굳 ### 4/5 — Bugs and request *2025-09-06, version 1.2.0* Network error: Generic error. Could not retrieve data. The request timed out.(after pressing submit button) Please adding some infrasound detector if its possible 🙏🏻 ## Most critical reviews (10 lowest-rated) ### 1/5 — 帥到閃退 *2025-11-17, version 1.2.0* 我還是太帥了 ### 1/5 — 無聊的東西 *2025-10-02, version 1.2.0* 嗎的老師強迫下載 ### 1/5 — 老師叫我們下載^^ *2025-09-03, version 1.2.0* 空間就要不夠了，還要下載，還當機欸💦 ### 1/5 — Dissappointing *2025-05-23, version 1.1.16* Does not give phone orientation (azimuth, pitch, roll), which was what I needed. Has “inclination” but does not clearly identify which axis is being measured. ### 1/5 — Cache-cache *2025-03-31, version 1.1.16* Lors d’une mesure de son la courbe fait un cache-cache. En effet, une fois elle est la et après elle est plus la. Je crois que cette application m’a fait me remettre en question ainsi que mon existence. Depuis, je pleure tous les soirs c’est donc pour cette raison que je déconseille cette application pour les personnes sensibles. ### 1/5 — absolument magique ! *2025-03-25, version 1.1.16* Ce jeu est une vraie pépite, une djoufara légendaire dans le monde du gaming. Son mode histoire est aussi captivant qu’un top 1 en solo sur Fortnite après une nuit blanche. Chaque quête secondaire est un challenge digne des missions les plus dures de GTA, et l’immersion est totale, bien plus que dans une partie de Pignouf entre tryhardeurs. ### 1/5 — I’m sorry that I am writing a one star review *2025-01-24, version 1.1.16* This app is very good, don’t get me wrong, but it costed me $140. This happened as I was testing out the barometer pressure sensor, I tested this by squeezing the phone. The screen was fine until the next day when it randomly got green lines and faded to black. This was quite scary since I was on a holiday in Japan, and didn’t know the language. I will remove this one star review when a warning is added or barometer pressure is removed from the app. ### 1/5 — 王嘉佑 *2024-10-24, version 1.1.16* 王嘉佑你也有今天啊 ### 1/5 — PHYS 159 *2024-01-26, version 1.1.12* 👎 ### 1/5 — 老師叫我們下載的 *2023-10-16, version 1.1.12* 我是被逼的（？ ## Most praised reviews (10 highest-rated) ### 5/5 — Get that data *2026-08-09, version 1.2.0* Your phone has a bunch of sensors that this app helps you access! ### 5/5 — Combine with an LLM! *2026-08-01, version 1.2.0* Guys! ChatGPT 5.6 Sol and Claude Fable can accurately and intelligently deconstruct exported .CSV data from Phyphox. They can generate a ton of charts highlighting the most useful observations. Just make sure you use high / extended reasoning modes, but you’ll genuinely receive mindblowing, high quality analysis of your data and is the perfect way to have fun with PhyPjox. Analyze your driving using this combo! It’s soooo cool. ### 5/5 — Hyper pédagogique *2026-07-28* Aide à mieux comprendre la physique. Mon seul regret est le wiki en anglais ce qui n’aide pas vraiment à comprendre les subtilités avec un niveau moyen ### 5/5 — Couteau suisse de la mesure *2026-06-28* Excellente application qui permet de transformer son téléphone en un outil de mesure très polyvalent. C'est traduit en plusieurs langues et en plus c'est gratuit. Que demander de plus? Eh bien la section commentaire de cette application permet aussi de détecter une grande variété de futur futurs génies du "stand-up" parmi nos chers jeunes élèves. C'est fascinant de voir autant de second degré et d'humour d'élite concentrés au même endroit. Le futur de la nation est entre de bonnes mains, et franchement... ça fait froid dans le dos. Cinq étoiles pour l'outil, zéro pour l'avenir de l'humanité. ### 5/5 — Pocket Sensor Suite Saved My Wife’s Sleep *2026-06-02, version 1.2.0* My wife was hearing an annoying high pitched noise and couldn’t figure out what caused it. After a few minutes of unplugging things, I remembered this app existed. Within seconds I had the Audio Spectrum tool open and isolated the frequency. I spent a few minutes playing hot / cold and found the culprit, thanks to this amazing free app. 100% worth sticking on your phone just in case. ### 5/5 — Facultatif *2026-05-29* Application ,vivifiante , interessante et qui sûrement changeras votre vie . Pour ma part c’est mon prof qui me l’a fait découvrir et vraiment pas déçu on peut calculer l albédo !! Je l aime je vais pouvoir calculer l albédo de mes feuilles de canabis à la maison Ps: J espère ne pas me faire attraper 😉 ### 5/5 — Chris Boden *2026-01-18, version 1.2.0* Chris Boden made me download it. worth every penny ### 5/5 — Hours of Phun! *2026-01-17* Good for hours of laughter if used correctly! I learned I fart in G shart. My son said it was the fabled brown note. But seriously, if you have an unquenchable curiosity, you need this app. ### 5/5 — Amazing *2026-01-08, version 1.2.0* Thank you ### 5/5 — Super *2025-12-28* Ich bin Physiker und dieses Tool ist einfach super. Ideal um unterwegs mal ein paar Messwerte aufzunehmen und sogar mit der Möglichkeit, eigene Sensoren einzubinden. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
