Comments on 21 Day Complete Reboot for Android

★★★★☆ Denise Sorrentino · Jun 9, 2016
Easy way to stay on track Great app which helps me stay on track with nutrition. I wish the app would offer additional workout program options to select, so I don't have to look at a paper calendar to know what workout to do each day when doing another exercise program (ie~22 min hard corps). Overall love the app right down to tracking my water intake.
★★★★★ Angela Smallwood · May 11, 2017
This is one of the best 21 day program app. Waited time and money purchasing portion control containers just to get the app that came with the containers, because I already have a lot of the containers because they have worked for me in controlling my weight. They are still one month later trying to fix the app it just does not work. So I started looking around on Google play for a replacement. I love this app the water reminder just goes through my soul every time I hear it lol! My weight count love it. The food I eat my exercise love! Love! Love! This app and I can't believe the price I would have spent more great job guys!
★☆☆☆☆ Camie Silva · Aug 9, 2016
Overpriced, overrated For a paid for app this is bottom of the barrel. I expected more. Unable to change the work-out to the one you're truly doing or record of you had injury or needed a rest day for one reason or another. I just wanted to track containers, but there isn't a free app for this. This isn't worth the money at all.
★☆☆☆☆ Latrisia Tait · Jul 9, 2016
I Was Exploring the App When... So I recently started the 21-day fix program and decided to get this app to help with tracking. I decided to see what the focus viewer (testing) is for. When asked for permissions to access my phone (camera I think) I declined and the word B**ch flashed at the bottom of my screen. Was it a joke...maybe, but I'm not in the business of being insulted.especially if I paid you for this app. I want a refund and am I uninstalling this app.
★★☆☆☆ Jeff DePorter · Jul 12, 2016
Nothing is simple, just want to use as basic tracker and that does not seam possible.

Reboot the way to track your 21 Day programs - meal items and containers, exercises, and water.

21 Day Complete has been the NUMBER ONE instrument in helping you accomplish your weight loss and fitness goals for years. We rebooted this past year with a new look and style. Now it's your turn! Fix it! Track it! Reboot it!

The 21 Day Complete Reboot comes with a base and an extreme 21 Day schedule; a robust meal planner style tracking system to fix your meal habits, and a report manager so you can generate measurement and weight reports (PDF). See your progress and SAVE IT!

Container Tracking: Control your meals!
21 Day Complete Reboot is NOT your typical click to subtract 1/2-portions. 21 Day Complete Reboot gives you the tools of a meal planner to focus on individual meal items and their portions you eat.

What did I eat?
✔ Daily meals report - view/export all 6 meals at a glance into a 1 or 2 page PDF reports.

My Meals!
✔ Create custom meal items that you can quickly add to meal planner - cuts down on the repeat typing.

Water Tracker
✔ We don't always drink using an 8 oz cup so why track that way?
✔ Chose from various size water bottles (in Settings).
✔ Ounces / Milliliters
✔ Edit water quantity anytime.

Grocery/Shopping List
✔ Gotta shop! We made it easier!
✔ Plan your trip to the grocery store! Create a list of foods you will need from the approved food lists.
✔ Add your own, sort, share/email - Honey Get List!

Reminders
✔ Stay Active and Hydrated!
✔ Set reminders throughout the day to drink water and get up n move.

Exercises

✔ Measurement Reports (before and after comparison)
✔ Weight Report (all 21 days in one PDF)
★ PDF reports for devices Android 4.4+★
★ Share reports to email available for all devices!

It takes your body about 21 days to make or break a habit (depending on the habit). Sometime you need to go through a few cycles to fix your meal habits. Reboot also contains a cycle manager. A cycle manager? What's that Tone? A cycle manager gives you the ability, at the end of your 21 days, to track another 21 days. NO MORE LOSING YOUR INFORMATION to do another round!
