The key to freemium monetization | ex post facto
Case study of Expensify’s effective use of getting users committed to their app. The main idea here is to get users to expend some amount of effort on a task. Once the user has invested themselves, they’re more committed to continuing to use the app.
A further point I’d make: it is important to reward that investment. The user is giving something of themselves to you, whether it’s time, effort, data, etc. Reward the user for giving to you. Achievements, an ‘atta boy’ in your app, whatever is appropriate. Without reward, expending effort becomes a chore.
