SDK Metrics

All SDK Metrics are presented in alphabetical order.

A

ARPU (Average Revenue Per User) - the average revenue generated by any user within a defined timeframe. Every user is taken into account. Defined as the total gross revenue within a given period divided by the number of active users within the same period.

ARPPU (Average Revenue Per Paying User) - the average gross revenue generated by a paying user. Non-paying users are not taken into account. Defined as the total gross revenue within a given period divided by the number of paying users within the same period.

Average check - an average gross revenue per payment. Defined as the total gross revenue divided by the number of payments.

Average session length - an average time spent in the app per user. Defined as the sum of the length of all sessions divided by the number of sessions within a given period.

D-G

DAU (Daily Active Users) - the number of unique users that have opened the app during a given day. The DAU for several days is calculated as the mathematical mean of all DAUs within the given period.

Day 1 retantion (by hours) - the percentage of users who have launched an app for the first time during the chosen period and then opened it on day 1 after the first launch ("day" here means 24 hours interval from the first launch).

Day 7 retantion (by hours) - the percentage of users who have launched an app for the first time during the chosen period and then opened it on day 7 after the first launch ("day" here means 24 hours interval from the first launch).

Day 28 retantion (by hours) - the percentage of users who have launched an app for the first time during the chosen period and then opened it on day 28 after the first launch ("day" here means 24 hours interval from the first launch).

Day 1 retantion (calendar) - the percentage of users who have launched an app for the first time during the chosen period and then opened it the next day after the first launch ("day" here means the date in the calendar).

Day 7 retantion (calendar) - the percentage of users who have launched an app for the first time during the chosen period and then opened it on day 7 after the first launch ("day" here means the date in the calendar).

Day 28 retantion (calendar) - the percentage of users who have launched an app for the first time during the chosen period and then opened it on day 28 after the first launch ("day" here means the date in the calendar).

Gross - the total gross revenue (Sales Revenue) within a given period. Defined as the sum of all payments within a given period.

L

LDAU (Loyal Daily Active Users) - a number of unique loyal users visiting the app during a given day. The LDAU for several days is calculated as the mathematical mean of all LDAUs within the given period.

Lifetime - the average number of days between the first and last time the app was launched. The launch is considered to be the last if there has been no activity within the app during the last 7 days.

LMAU (Loyal Monthly Active Users) - a number of unique loyal users visiting the app for the past 30 days. The LMAU for several months is calculated as the mathematical mean of all LMAUs within the given period.

Loyal user - user who has opened app at least once after 24h from the first launch.

LWAU (Loyal Weekly Active Users) - a number of unique loyal users visiting the app for the past 7 days. The LWAU for several weeks is calculated as the mathematical mean of all LWAUs within the given period.

M-P

MAU (Monthly Active Users) - a number of unique users that have opened the app for the past 30 days. The MAU for several months is calculated as the mathematical mean of all MAUs within the given period.

Max users online - max users online shows the peak number of users active at a particular day.

New users - a total number of registrations for the chosen period.

New paying users - the number of users who have made their first payment to the application within a given period.

Paying conversion - is the percentage of users registered in the given period and having afterwards made at least one payment, percentage taken of all users registered in the given period.

Paying share - the share of users who have paid at least once per given period. Defined as the number of paying users within a given period divided by the number of unique users within the same period (DAU, WAU, MAU).

Paying users - the number of users who have paid at least once within a given period.

R-S

Revenue - a total net revenue within a given period. This metric is calculated as the product of Gross and Revenue rate. "Revenue rate" (developer interest) is equal to 0.7 by default, but it can be changed in project settings.

Session - the total number of sessions (opening or unfolding the application) for the given time period.

Sessions by user - sessions by user shows the average number of sessions made by one user during the period.

Sticky Factor (DAU/MAU) - shows the average regularity of users’ logs. The more regular users log into app, the higher is Sticky Factor. If every user logs every day, the Sticky Factor is equal to 100%.

T

Total Gross - Gross + Ad Gross.

Total Revenue - Revenue + Ad Gross.

Transactions - total number of transactions made by users within a given period.

Transactions by user - an average number of transactions per user. Defined as the number of transactions (purchases) within a given period divided by the number of paying users within the same period.

Tutorial conversion - the share of new users who have successfully completed the tutorial.

U-W

Users online - the average number of unique users, from whose devices any event was received in the given timeframe. Calculation is performed with the use of averaged data for the 5 minutes period, days, weeks etc. depending on the period and aggregation taken.

WAU (Weekly Active Users) - a number of unique users that have opened the app for the past 7 days. The WAU for several months is calculated as the mathematical mean of all WAUs within the given period.
