Doesn’t make sense. I already own this one so why would I buy the “upgrade” for more money??? Sweet deal ### 1/5 — Stingy Developer *2026-06-23* Big money grab with this developer. What happened to the first version AUBE. What a rip off and to ask money for every update. ### 5/5 — Precise *2025-12-21* I cannot believe this is real ### 5/5 — love it *2025-03-27* great isolated multi band effects, use this one alot ### 5/5 — Here’s another star: ⭐️ (6/5) *2023-11-03* Some apps do what they say they do. Some have a little extra that make you use them more than you thought. This one will constantly keep making you sound better. I thought I would use it for a little color here and there and I now use it at least twice in every track. Awesome work from Mr Corvest. ### 1/5 — In app Käufe wurden nicht erwähnt *2023-01-02* Die reverbs und delays müssen extra bezahlt werden. **Developer response:** Hi "Extendable via In-App purchase in Bandit store: Delay and Reverb" - it's written on the App Store page description and on the website... All the best, ### 5/5 — 5 Star App - UPDATE *2022-08-06* Still killer like all the FAC apps! Like all of Frederic’s apps! BUY THEM ALL! I use at least 2 FAC apps on everything I do! Usually more! Sound great, nice UI! ### 5/5 — Fac always deliver *2022-02-04* Got all this guys apps and they are all excellent ### 5/5 — Great *2021-04-30* Great interface, great sound, great control. I have to say that a review to me is to know how good or bad an app is, not the price issue. I can decide for myself if I can afford it. It irritates me when I read a review that sounds like the person just wants to complain or is angry about life in general. I actually haven't found an app that does exactly what this one does. ### 5/5 — As Always *2020-12-16* You gotta hear it to believe it, Fac never disappoints ## Frequently asked questions about FAC Bandit ### What does FAC Bandit do?
