Ver 1.5 has removed a lot of useful tools from this app. Used to use this app all the time. Please add back the tools you’ve removed. An explanation? ### 5/5 — 10/10! *2020-12-12* Track all my routes with this app!! Such a simple streamlined interface. Thank you ### 1/5 — Doesn’t convert pace into speed *2018-11-08, version 1.1* Of all the things a runner might want to convert like converting pace from minute:miles to mph, this doesn’t do. The only calculations it does are ones you can do in your head in seconds. ### 5/5 — Useful tool! *2018-10-04* Very helpful little tool for calculating run paces/times/distances. ## Frequently asked questions about RunTools ### What are the main tools available in RunTools?
