Day 21 - Profitable MVP in 30 Days - Early Adopter Experiment

Final summary of the 30-day profitable MVP challenge, evaluating the entire development process of three different apps: SoundBar, ReadingPointer, and Focusify.

Days 28-29-30 of the profitable MVP challenge where I look back at the original plan and assess progress. Sharing how I plan to hit the $1000 profit goal by buying my own app, and announcing the new app Focusify.app instead of letmethink. Also preparing landing page, promo video, and images for launch day.

Day 27 of the profitable MVP challenge where I decide to abandon the Group Opener idea and pivot to building a 'silly app' - a simple, easy-to-build app that still has profit potential.

Day 25 of the profitable MVP challenge where I admit ReadingPointer's failure - user retention is extremely low and no one cares about the paid features.
