Read full descriptionHide full description
Gapzilla is a goal and event tracking tool. Create a goal and record two kinds of events: a slip that happened, or an urge you noticed in the moment. Gapzilla calculates the time between slips and shows the current, longest, and average gaps. An urge is stored as a raw event and does not reset the current gap. For a calendar day that has already ended, if an urge was recorded and no slip occurred that day, the Insights screen can include it in a retrospective summary based on that day's outcome. Key features: - Create and switch tracking goals - Record event type, date, and an optional note - Review history in a calendar and list - View current, longest, average, and historical gap trends - Review urge summaries calculated from completed calendar days - Sign in with Apple or a Gapzilla account and sync data - Sign out or permanently delete your account and related data in the app The iOS interface is Chinese-only.

The clearest difference is in-app purchases: Gapzilla at none against OIO's 4. Gapzilla also leads on update cadence (daily vs every 4 days). On price, ads, device support and iOS requirement there is nothing between them.
