Introduction
I have been contributing to the Actifit iOS Application development with my past contribution link posts Post 1 and Post 2. This contribution holds new features into the iOS App like support for lower iOS versions, allowing the user to post activity once a day and adding new leaderboard screen displaying daily top 5 scorers posting from Actifit App.
About Actifit
Actifit is one of the SMT(Smart Media Token) on the top of Steemit blockchain which rewards you Actifit tokens based on your activity posted to Steemit via App. You can then use these tokens to buy sports pieces of equipment. Actifit also rewards you STEEM via upvotes on your posts on Steemit.
Technologies Used
- Swift which has been used 100% in the project with best technologies and frameworks to track one's activity in iOS App.
- Realm along with Core Data that has been used to store user information and Activity track of records locally and safely.
Proof of work done
Daily Leaderboard (Top 5) Commmit Link
- We keep track of every user posting their activity on Steemit blockchain using the Actifit App and reward them based on their activities count.
- The top Actifitians get the most number of Actifit tokens reward and every user can see that in Leaderboard section.

Allow a user to post only once a day Commit Link
- User basically does his/her activity like running, jogging, etc.. keep tracking the activity while using the App and if the user reaches the 1000 activity milestone (minimum activity required to post on Steemit), then is allowed to post to the Steemit blockchain along with the post content, post title and some tags.
- Now user only can post only once a day so that he/she can track the maximum activity of the day before posting on Steemit blockchain to gain more STEEM rewards and Actifit tokens and also to have a better chance to be on the top leaderboard list.
Adding Activity tracking support for older iPhone devices(support for iOS 9 or later)
Commit link 1
- As Apple changes the API structure with every new iOS release, we need to add support for all the versions of iOS along with different code for different iOS versions so that API does not fail to low iOS versions.
private func checkAuthorizationStatus() {
if #available(iOS 11.0, *) {
switch CMMotionActivityManager.authorizationStatus() {
case CMAuthorizationStatus.denied:
onStop()
stepsCountLabel.text = "Not available"
default:break
}
} else {
// Fallback on earlier versions
self.activityManager.queryActivityStarting(from: Date(), to: Date(), to: OperationQueue.main, withHandler: { (activities: [CMMotionActivity]?, error: Error?) -> () in
if error != nil {
let errorCode = (error! as NSError).code
if errorCode == Int(CMErrorMotionActivityNotAuthorized.rawValue) {
self.onStop()
self.stepsCountLabel.text = "Not available"
}
} else {
print("Authorized")
}
})
}
}
The above code is for checking if the user allow the App to track user activity or not. As you can see for iOS 11.0 CMMotionActivityManager class can directly check if the user has allowed the App to track the activity. But for lower versions, we have to query activity manager for data between two dates, if there is an error CMErrorMotionActivityNotAuthorized then we stop tracking the activity otherwise we proceed tracking the activity.

On iPhones with a smaller screen size like iPhone 5S and iPhone SE, the above image showing measurement fields which fits the whole screen width.
On iPhones with bigger screens like iPhone 6, iPhone 6s, iPhone 7 and of similar category, the measurement fields which are bound in a single container have some space left on the right of the screen.
Roadmap
- Add View Wallet section so that user can see their total awarded Actifit tokens.
- Add a feature so that users can see all transactions history of awarded tokens.
- Background movement tracking.
- Switching between measurement system (Metric & US).
- Donate rewards to charity.
