Content Summary
The author shares their journey of creating Fluxkey, an iOS keyboard extension that helps rewrite and rephrase text in real-time to improve writing confidence and conciseness. The app was born from the author's personal frustration with constantly switching between apps to use ChatGPT for rewriting. Since launch, Fluxkey has gained 320+ installs and 37 paid users, generating $742 in revenue. Key successes include the iOS keyboard format as an ideal delivery method and a pricing model offering both lifetime and subscription options. Challenges include positioning the product as a writing assistant rather than just a keyboard, App Store discovery difficulties, and lack of an Android version. Future plans include improving onboarding, exploring email-based solutions for non-iOS users, and seeking validation strategies.
