Day 11 — Day 21 Summary
Weeks 2-3 focused on retention and organic growth. Added streak tracking, daily goals, and progress stats — these features dramatically improved daily active usage. Published content targeting 'Japanese vocabulary from anime' and 'Spanish from Netflix' which drove Reddit shares. Subscriber count grew to 9 with some churn (1 cancelled). Revenue stabilizing.
Learnings
Gamification features (streaks, goals) have an outsized impact on retention. The 'learn from content you love' angle (anime, Netflix) resonates much more than generic 'learn a language'. Churn is real — need to keep adding value to retain subscribers.
Results
9 active subscribers ($45/mo MRR, minus 1 churned = $40 effective). 2 cancelled and re-subscribed. Daily active users: ~35.
