Tips and tricks
• The main screen of the app contains the activities that you created.
• The Skills menu item allows you to manage skills (create, view, edit, delete).
• The Categories menu item allows you to manage categories (create, view, edit, delete).
• The Trends menu item displays some neat charts.
• The Store menu item allows you to manage products / rewards (create, view, edit, delete).
• The Transactions menu item shows the expense / income coin transactions.
• There is one category created by default: General. You can edit it, and you can add more categories by pressing on the + button when on Categories page.
• Icons for skills, categories, and products are mandatory.
• You can add activity only when you have at least one skill defined.
• Store is for user-defined rewards (see explanation below).

Store
The use of the store is completely optional. The main aim of it, is to allow the user to define some rewards for time spent developing a skill.

Examples:
• Gaming - you can purchase an hour of gaming using X coins that you got from developing a skill.
• TV Shows- you can purchase an episode of TV Shows using X coins that you got from developing a skill.
The idea is to allow you to define rewards for your time spent developing useful skills.

More icon packs will be added in the future.
More gamification features are going to be added in the future (feel free to suggest them).

The free version allows you to have a maximum of 7 skills at a time, everything else is not restricted.

Recent changes:
* Fixed order issue when viewing activities for a skill/category.
* Added sorting options for skills.
* Increased skill limit to 7.

Comments on Mastery for Android

★★★★★ John John · Jan 16, 2022
Great app. I love the simple easy way to put in entries. Other apps I tried are tedious and annoying. The icons are a nice touch to visually distinguish between skills. The organization of everything is natural and intuitive. Can't say that about other apps. I easily located the backup file in my phone's internal memory and saved it to Google drive. I imagine that file can be used to restore data if ever needed
★★★★★ Jon Salmon · Oct 4, 2019
Love this app. Very useful and I use it almost every day to track progress on skills. 2 things needed: backup to cloud (Google Drive, etc.). Also, if a timer is running and user returns to the app later to stop timer - resume on the timer screen (vs opening the main menu every time). Overall great app.
★★★★☆ Valerio Farruggio · Feb 14, 2018
It's a very simple app and it works excellently. I can plan much better now my guitar practice time, and it helps to organize all the work I have to do and making sure that all skills are equally developed. I would appreciate some deeper settings - such as a way to define a percent of time to each skill (not all the skills that you define need the same amount of time) - I know there is the coin multiplier thing, but that seems more related to the reward than to the time count. Other than that I like it
★☆☆☆☆ C Ioana · Dec 17, 2017
I've just installed this app, and I can't do anything in it. When I try to create a category (for instance), I have to select an icon. But the icon I tap on does not get selected, and I'm simply sent back to the previous menu, with all other fields reset to blank.
★★☆☆☆ Sanelle · Dec 3, 2020
I would love to keep using this app, but I'm a bit concerned that it hasn't been updated in 3 years, and the backup system mentioned by other reviewers might still not be working... I don't want to lose my data. It also would be good to have some sort of indication of how many levels there are and where you are up to (e.g., novice, newbie), and some sort of homepage. This app is such a great start to a tracker. Please let me know if you are still working on it, and I will increase my star rating
