Great and cheap
You can go up to day 5 for the 3 levels for free and thats enough since you can always redo the same exercise or do some extras. Even then you can choose between 3 sums of choice for the premium feature and you only pay once. So you are kinda giving them a donation if you choose the 2 bigger sums. I find this a good thing cuz this app work great but doesnt have a lot of features and its not like its an app that needs to get highly maintained. Im a developer and 2 dollars as a one time payment for what you get is a good deal. The UI could improve a bit but it isn’t necessary cuz it does what it supposed to do. They also have more apps like Start Running. Oh ye and it works with an apple watch if you start a workout via your phone. I like that cuz I cant always look down at my phone during an exercise to see what im doing. They also have this for Start Running app and there you can start a new run directly from your watch though there app. It has a couple levels where you also have walking pauzes
