If it were to be fixed, it would be four stars. I feel bad for the people who bought the premium impossible effect and can’t get it anymore. ### 2/5 — Stomp library is severely reduced *2025-07-30, version 1.0.9* If you are thinking no about buying a istomp please be aware only these effects are available: Octaver, envelope filter, compressor, screamer, redline od, rocket distortion, death metal, blue pearl chorus, jet flanger, phaser beam, double cross delay, total recall delay, and continuum reverb. Unfortunately there appears to be a server side error that the developer doesn’t plan on fixing so the rest of the effects ( most of which are much better) are gone. This has happens so the past but it’s never taken this long to fix. ### 3/5 — Unfortunate *2025-04-03, version 1.0.9* Looks like most of the effects that were available are now gone 🙁. I have a couple of these pedals and really liked many of the 44 different effects that were downloadable. Now it seems there are only the default effects left. I still have “glimmer drive” loaded onto my pedal. If I try to load another patch I would lose it forever… I think I’ll keep it ### 4/5 — What happened *2025-03-31, version 1.0.9* I bought these a couple years back. I know at that time most of the sounds were free. I hadn’t used them in a while. This year I decided to use them again. Now I can’t find my library of sounds anywhere nor can I redownload them. At one point I had all the sounds available. Yes, I can get these sounds on my line 6 pod but sometimes I just want a stand alone sound. ### 3/5 — There is an error in the app. *2025-03-09* I don't see the effector I bought in the shop menu. Please correct it. ### 3/5 — Pedals are gone again! *2025-03-08, version 1.0.9* Back to the 13 pedals instead of 47 I previously had. Please restore all pedals! And please continue supporting these unique and cool pedals as there are many of us who still use them regularly. ### 1/5 — most pedals now gone... *2020-03-03, version 1.0.9* where did they go? ### 1/5 — 5sで認識せず。 *2019-04-16* lightning機種じゃ何も出来ないんですね。ソフトウェアの対応も出来ないとはメーカー的に信頼持てなくなりました。画期的な物だっただけに残念です。 ### 1/5 — Where are my pedals *2018-12-16, version 1.0.9* All my pedals disappeared even ones I had bought ### 3/5 — Purchased Pedals are back!! *2018-10-12, version 1.0.9* Thanks digitech for trying to get this app back in order. Haven’t tried 30 pin to lightning adapter on my iPad mini, hoping for positive results. Will report back after I’ve tried it. Thanks again for your efforts!!! ### 4/5 — E-pedals are back! *2018-10-12, version 1.0.9* Thanks, Digitech, for restoring the app. The e-pedals are back, and I’m excited to use my iStomps again! ### 2/5 — Buggy *2018-10-02* Only 13 pedals available after update!! I need my fuzz, man! ## Most critical reviews (10 lowest-rated) ### 1/5 — Onde estão meus pedais comprados? *2025-12-31* Depois da atualização 1.1.0 não consigo restaurar compras, fica eternamente atualizando sem êxito. O que houve? ### 1/5 — Куда пропали эффекты? *2025-09-13* Куда пропали эффекты? ### 1/5 — Removed all the best pedals *2025-08-31, version 1.0.9* This was an awesome pedal for years. The variety was great and had pedals like xull that were never released in a single hardware form. Now it’s a handful of lame pedals. ### 1/5 — 更新後エフェクトの種類が少なくなった *2025-07-23* impossible pedalを購入後スワイプダウンして一覧を更新したらエフェクトの種類がめちゃくちゃ少なくなってて買ったはずのimpossible pedalも一覧から無くなってて3000円引き落とされたのに使えない、返金してほしい ### 1/5 — Removed all the best pedals *2025-06-18, version 1.0.9* This was an awesome pedal for years. The variety was great and had pedals like xull that were never released in a single hardware form. Now it’s a handful of lame pedals. ### 1/5 — Where are all the pedals? *2025-06-16, version 1.0.9* I had all the 44 pedals downloaded to my iPad Mini, but I plugged in a new-to-me iStomp and a bunch of my pedals disappeared from the stomp shop. How do I get them back? ### 1/5 — What Happened? *2025-05-01, version 1.0.9* Why are all the pedals gone? It makes absolutely no sense and renders the whole thing useless. Bring back the options. ### 1/5 — Где все Педали эффектов ? *2025-04-28, version 1.0.9* По какой то причине пропала половина педалей из библиотеки . У меня были все а теперь только половина примерно .в чем проблема . Когда вернутся все Педали ?Почему производитель молчит ? ### 1/5 — Where are all the pedals? *2025-02-25, version 1.0.9* I had all the "free" pedals downloaded to my iPad Mini, but I plugged in a new to me iStomp and a bunch of my pedals disappeared from the stomp shop. How do I get them back? ### 1/5 — pedals I paid for gone!!! *2025-02-08, version 1.0.9* I opened this app today to discover that the 30+ pedals that used to be there are now gone. I checked my old iPhone and saw them all there but as soon as I attempted to load one that I paid $20 for it and all but five pedals disappeared! That is literally theft. Digitech took my money and then erased the pedal I purchased. I'm contacting my States Attorney General to lodge a legal complaint. I will not stand for this ## Most praised reviews (10 highest-rated) ### 5/5 — Mise à jours iOS 11 *2026-04-19* Il y a plus que 14 effets au lieux de 47 bug ? ### 5/5 — Pedals are BACK! *2021-02-05, version 1.0.9* Thank you so much for continuing to support this app for old phones and new phones! I use my original iPhone 4 30 pin lightning connector, I have every single phone loaded into that device including the impossible pedal which it actually took me a while to figure out how to use because it really doesn’t do any other effect but make the shift jump to a random position so that it sounds like you are a madman! Ha! But it does take some kind of arbitrary skill to figure out exactly how to use Impossible Pedal. I have tried every single effect even purchasing many of them when I originally got this unit almost 8 years ago? I wish I had more iStomp units. My favorite effects are Swing-Shift pitch shifter and the Redline Overdrive which is as close to my old Proco Rat as I ever had. I don’t know why the pedals vanished from time to time but I appreciate that they are all back now, thank you so much. You really should have kept developing this product with new updates and new effects, I think there is so much more that this system can do compared to those TC pedals. TC can load an effect using a tone generated from your iPhone directly into your pick up, and that is much easier, but I find that The Digitech system is much more complete, it does not merely load a preset into the device, it loads entirely different digital effects that mimic other popular COSM pedals. It would have been great to get amp models loaded into this thing as well as effects models. Even now I think if people were to design effect models that would work with this product they could be added. ### 5/5 — Top notch spring reverb'! *2020-04-26* I use the spring reverb in my board. Nothing compares to it! ### 5/5 — Thank you for bringing all the pedals back! *2020-04-14, version 1.0.9* Now I can use the iStomps again! ### 5/5 — Pedals are back again! *2020-03-05* Thanks Digitech for restoring the missing pedals once again. We now have access to all 47 pedals! Please continue supporting these unique and cool pedals as there are many of us who still use them regularly. ### 5/5 — Top work restoring the missing pedals *2018-12-19, version 1.0.9* I just bought an iPod touch and set it all up again. Digitech technical support have fixed a problem with missing pedals. Having restored the effects, there is DSP in this pedal that make it worth buying. It still seems to me that Digitech created a fabulous device which is extremely innovative and useful. Yet iOS fails to deliver a platform that’s suitable for professional music makers. It would be fabulous if Digitech shared the code on GitHub so third parties could develop other was of organising iStomp. ### 5/5 — Thanks for the update! *2018-11-18, version 1.0.9* Now works with iOS 12! Thanks, DigiTech! ### 5/5 — Danke !!! *2018-10-16* Es läuft wieder. Nachdem ich diese App und einige, dieser „Tretmienen“, seit Jahren intensiv nutze, war ich natürlich sehr verärgert, als die App plötzlich nichtmehr funktionierte. Was auch immer das Problem war, es scheint behoben zu sein! Meine gekauften Effekte sind wieder da und auf den Pedalen speicherbar. Also, es läuft wieder. So kann ich diese App und die Gitarreneffektpedale wieder wärmstens empfehlen! ### 5/5 — Manque des effets *2018-09-17* On est passé de 47 à 12 effets c’est normal? Sinon super appli et produit .Vraiment dommage que cela n évolue plus. ### 5/5 — Ура иос11 *2018-08-11* Наконец-то обновили! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
