It’s incredibly easy to use worth downloading xoxo ### 4/5 — Promising app with some surprising results *2021-04-13, version 1.0* I haven’t used this in clinic yet but I’ve had a play around with some hypothetical numbers and found in one case that it was preferable to programme 3.5V@0.8ms over 3V@1ms which I wouldn’t most probably wouldn’t have done in practice. I’m interested to see what the future holds for this app! ### 5/5 — So interesting- Worth the money *2021-04-12, version 1.0* This App is fantastic and a must have for those passionate about optimising cardiac devices! The results can be surprising and definitely worth using! ## Frequently asked questions about Altilium ### What is Altilium used for?
