The worse reviews are just because of the difficulty. You can make it easier or harder just by pressing the star at the top right and choosing a level. I agree with one review saying that after the quite frequent rest days, it adds 14 seconds to your time to plank, which IMO is a lot. The app doesn’t have any glitches and the ads are fine. I like the little reminders they send you. Only complaint is that the rest days are quite frequent and there is no way to change them. I think all it needs is some more customization (like being able to add or subtract time to make it easier or harder, or being able make the rest days more or less). Either way, the app is great, and I would recommend it to anyone who wants nice abs!!!

This app does good for anyone who really wants to strengthen your core, I use this app along side of using the wheel to really help my get my core back in good shape.. Don’t forget to get more cardio into your workout so not only you feel the muscle tightening back up but you will be able to see the results as well...i like the company because they also have the pushups & squat challenge..

Sit-ups shown are not good for spine so I decided not to use this app.

This app help me with my core and makes me stronger day by day . All you got to do is do it everyday

This has preset times in the app. I am already well past the 20 second plank so I want to be able to put in my own times. Uninstalled

The challenges start off easy enough but definitely do get tougher. Once you hit day 20ish the difficulty sets in. The timer doesn’t seem very accurate. I swear it changes speeds throughout each challenge.

Haven't had a chance to use app yet but would love to see an option to invite other friends that use app to challenge and be notified when they complete their challenge for the day. Similar concept with fitbits. Looking forward to using the app for challenges!

App is basic but good at what it is. The optional daily reminders are nice, and the timer function is what I really needed. The daily progression of 7 additional seconds is doable - but after a rest day (which do seem a bit frequent), it jumps by 14sec instead. Which I know doesn't sound like a lot, but once you are really pushing your limits can be too challenging. I wish there were a way to select frequency of rest days and to reduce the time increase after them to the same 7 sec, but overall a good app for what it does.

I tried several apps before this, but that's the only one that I'm happy with. I upgrade to the full version, and I will use it for months.

Really like seeing my progress using this app!
