An app performance survey asks users what speed and battery use feel like on their own phones, which lab tests and crash tools can miss. This template takes about 35 seconds: how much the app drains the battery, the screens that feel slow, and the phone they use, grouped by maker and age.
It is written for the week after a major release, sent by email to a list of active users, where the battery question sits inside the email and a tap opens the rest. Send it again by hand after each release, since Usertick has no recurring sends. The survey's link also works from your app's release notes or settings screen.
Results shows a donut for battery drain, bars for each slow screen with every typed Other answer listed, and a donut of phone groups, each against the period before. Select A lot to filter the whole page and see which screens and phones those users report. Usertick reads every typed answer and files it under a category such as speed and reliability.
