Day 16 - Profitable MVP in 30 Days - Testing App, Hiring Designer on Fiverr

Final summary of the 30-day profitable MVP challenge, evaluating the entire development process of three different apps: SoundBar, ReadingPointer, and Focusify. Detailed analysis of revenue, costs, actual profit achieved, along with valuable lessons about choosing business models, focusing on one product instead of spreading resources thin, and future plans for the developed products.

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. Explaining what silly apps are: simple features that seem unremarkable but can achieve massive downloads, like fart sound apps with 50 million downloads or beer drinking simulators with 90 million downloads.

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. Sharing lessons learned including targeting users with higher willingness to pay, challenges of building cross-browser extensions, and difficulties turning scientific methods like speed reading into products.
