Help shape MileSprout
We built MileSprout because tracking mileage for tax is a pain, and most drivers give up halfway through the year. It logs your drives by itself, works out what your work miles are worth, and keeps your trips on your phone.
It's nearly ready, and we want it tested by drivers doing real shifts. Not friends being nice: we need you to try to break it.

Questions
What's TestFlight?
Apple's own app for trying apps before they're in the App Store. Install TestFlight from the App Store, open the invite we email you on your iPhone, and MileSprout installs like any other app. New versions arrive through TestFlight too.
Is it free?
Yes. Testing costs nothing and there's no card to add. When MileSprout launches, we'll send you a code for 12 months of Pro. After that it's up to you: tracking stays free with no monthly limit, and Pro is optional.
What data do you see?
Your trips, places and earnings stay on your phone. The app doesn't send them to us, and there's no account.
We only get your email and what you choose to tell us on this form (plus a tag for the group or link you came from), and whatever you send us: screenshots, comments and your check-in answers. If you allow it, TestFlight also shares crash reports with us. More in the privacy policy.
Can I stop?
Any time. Delete the app, and use the unsubscribe link at the bottom of any email. A line to say why would help, but you don't have to.
