Best app I’ve ever used to track workouts

If you’re like me and want to keep a close eye on your lifts and progression, this is the app for you. There is a subscription fee which is the most annoying part of the app, but it keeps the developer in business and with the frequent improvements it’s well worth it. I love the Apple Watch app so I can quickly look at my wrist to see what is next up in my routine and log my workouts. The app keeps track of your rest time so you don’t have to think about it. I used to have to open the Stopwatch in the Clock app and switch back and forth between Excel–where I previously stored my data. The little tap on the wrist when using the Apple Watch app is helpful and makes for a great user experience. The data visualization for each exercise is useful and there are too many features to list that are awesome. I want to highlight my experience going outside the US. When I went abroad, I had to use metric plates since everyone else uses that. With a simple setting change all my previous lifts were converted to metric so I didn’t have to sit around doing conversions to know how to load the bar. Afterwards, you can simply switch back to pounds and all the data you collected overseas is converted back to US units. For anyone who wants to get into working out and keeping a tab on their improvements, this is the app to get.

Amazing App, Amazing People!

My mom and I have both allowed ourselves to get so busy with life that we allowed ourselves to get off of our diets, and not be able to find time for the gym. I work on ships at sea for months at a time, so it's not always easy to eat healthy or workout. While I've been home on vacation, we have been in the gym every day, and have both been on the strictest diets. I'm down almost 40 pounds in 6 weeks, and she's also doing incredible. I don't tell you this to brag, I tell you this because your app has enabled us to continue this lifestyle when I go back to work. I had to leave last week for training, then I'll go home for a week then head back to sea. Because of your app, I was able to build some workout routines so that my mom can know exactly what exercises she needs to do each day to continue to succeed while I'm not there. You have LITERALLY set us up for success.

I just purchased this app and I’ve used it for the first time in my workout this morning. The first major flaw that I see is that it will not calculate the calories you burn during the workout session logged. It also does not keep track of the total time you have worked out. It does offer you the opportunity to set rest periods in between sets but does not keep track of your total workout session time. It also does not appear to allow you to enter a custom exercise or movement. I have been using Fitness Buddy for 9 months and dont like it well enough to buy the subscription but what it does do is track your session time and calculate calories burned. The calories burned number then populates the apple health app as well as “My Fitness Pal” where I log my calorie intake and research foods. What I do like so far is the the data entry interface. I find it very intuitive well thought out, easy to log sets, weight and reps. It is color coordinated making things easier to see or identify. I also like that this app syncs with my apple watch really nicely. I also like that this app doesn't force you into a bunch of stuff you dont need or want. So far I wont start the subscription unless they add these features that are important to me. While I dont like Fitness Buddy it does do the minimum most that I need for it to do.

Update: I found the workout timer. Cant find how to pause it if needed. Still unable to find a calorie consumption calculator.
