"I was feeling bored of running alone. (Vi) has become a part of my routine and more like a friend who encourages me to keep going on. I am in love with Vi."

"I have always wanted to try out a personal trainer but couldn't afford to. Vi has been just that without the regular fee! I have also gone down from a size 14 to a size 10!"

Verified Purchase

"When I was first starting to run, I had no idea what I was doing. Vi has taught me all of the essentials like rhythmic breathing, keeping a steady pace, and taking shorter strides."

Verified Purchase

"Her sense of humor is great. I actually burst out laughing while running on the road when she said something funny."

Verified Purchase

"With the help of Vi I now run 3-4 times per week and track my walking as well. I have lost 12 lbs. and am only 3 lbs. away from my current weight loss goal. I lost a full pants size."

Verified Purchase

"Probably the thing I have found most useful is the stepping-to-the-beat. This is a huge improvement and something I always tried to improve on in the past but never made it stick. Vi has gone above and beyond sorting that out!"

Verified Purchase

"I got a real time account of my pace and heart rate which really helps when I am trying to stick to a particular speed. You can't get that with a human personal trainer."

Verified Purchase

"I've lost 50 lbs. I have tried multiple apps but having Vi run with me and be so knowledgeable about me as a runner has been second to none."

Verified Purchase

"She's portable! I love I can put on the earbuds and tuck my phone away and go run. I don't have to worry about having multiple watches to track my cadence, heart rate, route, etc. Vi does it all for me."
