Good to know
Who can see my records?
Only your team, by the role you give them. Your data is never sold or used for training. Privacy.
Where does my data live?
On our server, not your phone. Sign in anywhere and it is there; a lost phone takes nothing with it. Details.
Is it on the Play Store?
No. You install it from this site, and it updates itself. How to install.
Is there an iPhone version?
Not yet. Use it in the browser on your iPhone. Tell us if you need one.
Try it today.
In the browser, or on Android 8 and up.
