Ya no funciona. Se cierra sola. Espero que lo puedan solucionar cuanto antes. ### 3/5 — Descepcionante. *2024-03-02, version 1.9.16* Mucha latencia y pobre calidad de sonido. También tengo la versión de escritorio y fue una pérdida de tiempo y dinero. ### 2/5 — É bom, mas precisa melhorar *2023-10-08* O aplicativo não reconhece o pedal Blueboard. Alem disso, notei alguns travamentos quando baixei alguns patches. Outra coisa é que seria muito bem vindo se fosse possível importar algumas funções do JamUp, como o Jam, o Sampler e o 8-Track. The application does not recognize Blueboard . Also, I noticed some crashes when downloaded some patches. Another thing is that would be very welcome if we could import some functions JamUp like the Jam , the Sampler and the 8-Track . E pra fechar, não está fazendo login nacloud via Facebook ### 2/5 — Configurar nuevos presets *2023-08-25, version 1.9.16* Con la versión 1 de BIAS FX Tenía muchos pedales y amplificadores, no me deja guardar presets nuevos que configuro, se pierde la configuración cada que salgo de la app, es tedioso, tampoco me puedo conectar a Facebook para tener mi cuenta. Siento que me obliga. A cambiarme a BIAS FX 2, pero no puedo llevarme todos los pedales ni amplificadores que he comprado ### 1/5 — 👎🏻 *2022-11-11, version 1.9.16* No longer working after i tried to used Bias FX too sad that I bought the upgrade. ### 3/5 — Great but Liking compatibility with voiceover *2022-09-12, version 1.9.16* I have purchased this app, thinking that it would be compatible with my voice over. unfortunately it is not. if it’s not too difficult, please make it accessible to Visually impaired people by making it compatible with voiceover. Thank you. ### 1/5 — Acquisto senza rimborso *2022-09-04, version 1.9.16* Ho acquistato BiasFx 2 Elite e Bias Fx chiedendo il rimborso di Bias Fx 1 dopo essermi accorto che esisteva una versione superiore.Anche se ho chiesto subito il rimborso Apple non ha approvato. ### 4/5 — Musician *2022-08-25, version 1.9.16* Tq for the great apps ### 1/5 — Not connect *2022-03-25, version 1.9.16* But mid cintrol inot connect to irig blueboard,, ### 1/5 — Very disappointed. *2022-03-10* So I’ve downloaded bias amp and bias fx2, and so far bias amp is by far better than fx2, because I GET TO PLAY WHAT I WANT. On bias fx2 you have to buy the amps but they don’t tell you that, which is a ridiculous tactic for drawing people in as customers. I can play whatever amp I want almost on bias amp but I’m limited to 2 horrible sounding amps on this app? Did anyone think that part through? I’m very disappointed by my experience and I thought highly of bias after seeing a lot of YouTubers and music artists playing a loomis amp or an Orange rocker verb or whatever heavy amp on the “FREE” version. This is obviously a “pay for functionality” gig and I’m taking a hard pass on this one. If I have to pay to play on a mobile app, I’ll stick to my GE labs and my real amps. ### 1/5 — Not happy *2022-01-21* I’ve bought the full version years ago and now I hava a lot of stufs blocked. I cold restore my purchase but my effects, pedals and amps is blocked ### 1/5 — App Betrug *2021-12-25* Habe die App um 2 Amp Sound Pakete erweitert . 20 EUR ausgegeben für nichts. Die Erweiterungen werden nicht angezeigt. Für mich klarer Betrug . Nicht kaufen, Abzocke. Funktioniert seit kurzen gar nicht mehr , Finger weg . **Developer response:** Hi Ironmanfranky63, we are really sorry for the problem. Did you mean you have bought the expansion pack but it didn't unlock? Please write us on https://help.positivegrid.com/hc/en-us/requests/new and tell us more about it. We will provide more information and help there. Thank you. ### 2/5 — Tienda *2021-08-30, version 1.9.16* Me gustaría que la tienda esté disponible, hace mucho tiempo que no puedo comprar nada. Y necesito comprar nuevos pedales. Ya es hora de que puedan dejar a los usuarios de Bias Fx 1 volver a comprar en la tienda de la app. Muchas gracias ### 3/5 — Can’t change output on my iPhone *2021-08-20, version 1.9.16* Hello guys. How I can change the output on my IPhone 11? I have Irig HD, and I want to put all sound from iPhone to my bluetooth headphones, because iPhone 11 don’t have a 3,5 jack input, and I hear sound only from dynamics my iPhone… Also don’t work as well “ transfer expansion packs from bias fx to bias fx 2 “ function. Can’t work with old presets… Fix it, please… ## Most critical reviews (10 lowest-rated) ### 1/5 — Locked out it feels like when I paid cash *2025-10-23* I paid lots of money for the software many years ago and it won’t let me sign in on my computer. It’s like blocking me so you might end up paying for this software and it might become obsolete and they’ll abandon it and stuff so because of that I wouldn’t buy anything new from this company. ### 1/5 — Rip off *2025-02-02, version 1.9.16* I was ripped off by this company. I purchased add on to the app. When I switched to a new iPhone. They deleted my account. No class. Jerks ! ### 1/5 — Pésimo soporte de aplicación *2024-03-27, version 1.9.16* Soy usuario de bias fx1 funcionó bien hasta que salió biasfx2… No funciona nada ahí…. Diría que tengan cuidado cuando compren esta aplicación.. es muy buena pero se han desentendido de mi como cliente… aun cuando compre su versión mas cara en su momento…. Esto no es bueno. ### 1/5 — Complete rubbish *2023-12-14* Downloaded the basic pack to get a feel for up to date amp sims on pad and phone. Zero option to audition anything, permanent massive dither on sound like a vibrato pedal and massive switching noise ringing throughout. If you think this is how to get people to upgrade to anything, you’re crazy! Deleted app, going elsewhere fast. ### 1/5 — 소프트웨어 업뎃 이후 작동을 안합니다. *2023-12-11* I track dock 와 쓰고 있는데 충전은 되면 기타인풋 반응이 없네요. 속히 고치셔요 ### 1/5 — Crash *2023-12-09, version 1.9.16* Seconds after opening. Makes one reluctant to purchase when at some future point an app you sunk some dollars is now unusable. Couple apps that I liked are now gone. I don’t purchase those if they become reissued / updated. ### 1/5 — Empresa de chantas *2023-10-15, version 1.9.16* Cuidado con esta empresa de chantas y mentirosos. Prometen opciones “coming soon”, las compras y cuatro años después aún no se pueden usar. No responden ni dan explicaciones. Dense una vuelta por su asqueroso foro lleno de spam y fishing. Lo más probable es que sea de ellos mismos. ### 1/5 — 我是电吉他，不小心买了贝斯的扩展包，不让退款 *2023-08-27* 没有标明好贝斯和电吉他的效果器 ### 1/5 — What da hell boi *2022-12-28* Don’t know how to use ### 1/5 — Fraude *2022-11-13, version 1.9.16* Compré la versión full según las actualizaciones serían sin costo y sacaron bias fx2 para cobrar nuevamente ## Most praised reviews (10 highest-rated) ### 5/5 — Best app *2026-06-16* This is the app which makes the guitar sound heavenly. It connects to all my electric guitars(23) without any lag. Keep updating the app for more smooth performance. ### 5/5 — Hardware *2026-01-09* I have an iPhone 15 I want to use this on. What Type - C hardware should I be using to record direct to my interface? ### 5/5 — Doğan *2025-08-15, version 1.9.16* Klarnet için tonlarda yardımcı olur musunuz riça etsem ### 5/5 — Compré todo el paquete de 80 pedales pero no me deja ingresar con facebook, *2024-10-04, version 1.9.16* Agradecería la ayuda para ingresar y disfrutar de la compra ### 5/5 — best audio amp *2023-04-24* Really does a great job , bias fx2 is the best simulation bar none . Always practice with it, even if I own a fender deluxe reverb and marshall jcm 2000, this thing when plug with earphones is perfect for practicing loops, songs with amazing slow downer …. ### 5/5 — The best guitar processor software for ipad !!! *2021-07-29, version 1.9.16* I’m using on ipad pro with Apogee Jam96K and is amazing!! Few bugs in the new version but they will repare it soon.... ### 5/5 — Amazing *2021-05-10, version 1.9.16* 15 years ago, I would never us digital modeling. Now this is super convenient and sounds very good. The rigs are really nice and many option for customizing. Worth the money! ### 5/5 — Desktop version *2021-03-12* If i buy desktop version bias fix, can i use my account, tone cloud for mobile version? ### 5/5 — Verygood *2020-12-16* For ever bias fx ### 5/5 — Crashes on startup iOS 14 [fixed] *2020-12-03* Need this app to migrate to bias fx 2, but the app doesn’t open. Developer posted that they’ll fix it on 22 September, nothings changed since then. Fixed in a couple of weeks which allowed me to migrate to bias fx 2, changed rating on that basis. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
