MetricTracker

For daily tracking of good and bad habits, medication, incidental usage (e.g. painkillers). This app focuses on simplicity, a clean interface without fluff, privacy (all data is stored locally we never see any of your data), speed, and the data visualizations are opinionated and focus on the 3-month window so that you can instantly get a sense of how the things you track are going on a 90 day period. There are two main screens called "log" and "trends". Swipe left/right to go between them. The "log" screen shows your weekly history and is for data entry. The "trends" screen is for long-term data visualization. The point of this app is to make it easy to log stuff and then to instantly access long term trends. The long term trends are displayed as bar chart timelines with expandable monthly, quarterly, and all-time statistics, time-of-day patterns. Each metric lives on its own card showing your last seven days. Tap once to log at your target, or open the numeric input for precise entry. From here you can open the calendar (by tapping the calendar icon) for viewing and editing previous entries. The app is free to use for up to three cards. Then you have to pay your currency's equivalent of 12 CAD and that gives you lifetime premium access without annoying recurring fees. Pretty sweet deal if you ask me. I built this app for my own usage, not really to make money, so I don't really expect to make my time back in money, but by following this philosophy I know that it will at least be useful for one person, and I hope it can help you too! This app supports 40 languages. If you find an issue with the app or you don't like something about it, LET ME KNOW and I will do my best to improve it!

Verdict
Elephas and MetricTracker are too close to call on the numbers: across 5 compared parameters — price, ads, in-app purchases and device support among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.
