Every developer dreams of building the next big SaaS.
We imagine dashboards, AI features, user authentication, analytics, subscriptions, APIs—the list never ends.
I had the same mindset until I started building ScriptTimer, a web application that estimates how long a script will take to speak before someone records a video, podcast, or presentation.
Ironically, building the product changed the way I think about software.
The biggest lesson wasn't technical.
It was learning when not to build another feature.
The original problem was surprisingly small
The idea came from a simple frustration.
I'd write a YouTube script and assume it would take about five minutes to present.
After recording, I discovered it often took eight or nine minutes.
The word count looked reasonable, but speaking speed changed everything.
I looked for a quick way to estimate the duration before recording.
Most solutions either required unnecessary steps or included features I didn't actually need.
So I decided to build one.
My first mistake: planning too many features
Like many side projects, the feature list grew almost immediately.
I wanted to add:
- User accounts
- Script history
- AI suggestions
- Export options
- Team collaboration
- Analytics dashboards
- Multiple workspaces
Then I asked myself one question:
Would any of these features solve the user's immediate problem?
The answer was "not really."
Users wanted to know one thing:
How long will this script take to speak?
Everything else could wait.
That realization completely changed the scope of the project.
The MVP became much smaller
The first version only needed four things:
- A text area for the script.
- Word counting.
- Speaking speed selection.
- A duration estimate.
That was enough to solve the core problem.
Shipping a focused MVP also meant I could start collecting feedback much sooner instead of polishing features nobody had requested.
Performance became part of the product
Utility websites have different expectations than social platforms or enterprise software.
People visit because they want an answer immediately.
Every extra second feels like friction.
While building ScriptTimer, I tried to keep the experience lightweight by:
- Reducing unnecessary JavaScript.
- Avoiding large third-party libraries where possible.
- Optimizing the page for mobile devices.
- Keeping the interface clean.
- Minimizing clicks before the user gets a result.
Fast software isn't just a nice-to-have—it becomes part of the user experience.
SEO influenced how I structured the application
One lesson I underestimated was how much information architecture affects discoverability.
Instead of putting every calculator on a single page, I created separate pages for different user intents.
For example:
- Words to Minutes Calculator
- Speech Timer
- Podcast Timer
- Reading Time Calculator
- YouTube Shorts Timer
Each page focuses on one specific problem while remaining connected through internal links.
It helps users find the right tool and creates a clearer structure for search engines.
Shipping is only half the job
I used to think development ended when the application went live.
It doesn't.
After launch, I spent far more time on:
- SEO
- Technical improvements
- Writing documentation and articles
- Guest posting
- Product directory submissions
- Collecting user feedback
The code may stay the same for weeks, but the product continues evolving through user interaction.
What I'd do differently
If I started another SaaS tomorrow, I'd spend less time thinking about features and more time understanding the problem.
I'd also launch sooner.
Real feedback is more valuable than assumptions made during development.
Users have a way of revealing problems you never considered.
Final thoughts
Building ScriptTimer reminded me that software doesn't have to be complicated to be useful.
Sometimes the best products solve one frustrating problem exceptionally well.
For developers working on side projects or micro SaaS ideas, my biggest takeaway is simple:
Start with a problem that people actually experience, build the smallest useful solution, and let real users decide what comes next.
I'd love to hear from other developers:
What's one feature you removed—or decided not to build—that ultimately made your product better?
