This would be very helpful due to many clients use this when factoring run parameters. **Developer response:** We will add for the next version. Thanks for the feedback. ### 5/5 — Great App! *2020-02-13, version 1.0* Lots of useful stuff here - nice work! ### 5/5 — Flow Calculator *2020-02-13* Excellent app to determine ILI tool or cleaning pig speeds and run duration with selection of your preferred units of measurement and even a sliding Scale to raise or lower the volume flow rates or pressures in case of gas lines. Very user friendly! ### 5/5 — Finally *2020-02-13, version 1.0* Wow! An app to calculate tool speeds, FINALLY! No more pens and papers to figure out run times. Easy to use and offers all the wall thickness and pipe line sizes out there. Genius. Definitely going to be recommending this app. ### 5/5 — Handy Pocket Companion *2020-02-13, version 1.0* A nicely made app with very useful features and tools. There is no need to bring out the charts and excel tables, it’s all in the app! ### 5/5 — Outstanding. *2020-02-13, version 1.0* Lots of useful stuff in here for pipeline integrity engineers. ## Frequently asked questions about ILICALC ### What units does ILICALC support for flow rates and pressures?
