No frills or anything like that but it seems intentional for what it is supposed to do. I do wish you had the option for water intake to have measurements in oz and cups instead of just liters. I mean especially since everything is measured up to a gallon as the goal. Also I’m a big dude, it would be nice to have the weight limit go higher than 350 lbs, and have the option to type in the weight instead of having to scroll to it everyday. Same thing for the weight as with the water, they should have both imperial and metric measurements. Seems odd the way they have it constructed now. This is why I gave it three stars. Nothing bad but it could be better.

This app is simple and straight forward, but it has several issues that make it very annoying to use.1. Water intake - the goal is a gallon, but the only way to track water is by liters. The real issue though is if you want to quickly add up to a gallon at the end of the day, you have to click +1 liter 4 times but wait for the little water animation between each tap. This drives me crazy because I honestly want to just check the box (I track the gallon in my head, so I don’t need to be adding each liter throughout the day). Super bad UX in my opinion.2. Weight tracking - each day when you go to update your weight the value resets to 80 lbs, but when you click it it opens a drop-down that starts at 40 lbs. So not only does it not remember your data from the day before, it also forces you to scroll all the way down to your current weight (even just a typed input would fix this).3. Daily tracking - I prefer to use the app to checkin each night, but every time I open the app it accuses me of failing the challenge because I didn’t, I dunno, religiously check in at 6:30 am that morning? It just slowly got more and more annoying to have the app assume I was failing.These main points make the app not worth the cost, and also not a better alternative than just using pen and paper or like a notes app. They’re such simple fixes so I hope the devs improve it soon.

This app is horrible. This is not the official app of 75 hard, super annoying usage, lots of bugs. Right now I can’t see my progress pictures. I’m on day 60 and when I’m passing pictures by picture (which the fact that the app does not give you a library where you can view multi images at a time is already EXTREMELY ANNOYING AND POORLY DESIGNED) the app freezes around day 53, shuts off and I have to open it and start from the beginning. Just to go to the same thing and get the same error. When you add your weight, instead of keeping it the same in the next day, the scale in the app take it back to the starting number of 80lbs (standard by the developer) and you have to go all the way to your weight again. It’s just poorly designed and it does not worth your money. Don’t waste your money on this.

-if you forget to click on a task you complete (reading a book which I do before bed) it prevents you from moving to the next day. For example on day 18 I didn’t select that I read before falling asleep. Upon waking up on day 19 it asked if I failed the challenge. It then allows you to click that you’ve read or anything else you may have forgotten to add but then it keeps you on day 18 or whichever was the prior day without being able to advance to the current day. I’m now 3 days behind because of this glitch even though I’ve competed all tasks daily -manually input weight even though that’s not part of the challenge, just takes time.-the water doesn’t allow you to easily check a box. I drink a gallon of water on my first workout but have to select it 4 different times.
