Building simple web tools

About

I'm building No Pay Just Use, a collection of simple web tools designed to solve small everyday problems without unnecessary friction. I'm currently working on a Pomodoro and focus tool, with more productivity and utility tools planned.

What’s the smallest limitation that made you leave an otherwise good tool?

I keep running into the same strange moment with small online tools.

You find one, try it, and it works.

Then you decide to actually use it.

That s often when the limit appears an account, a paid feature, a usage cap, or an upgrade right in the middle of the thing you were trying to finish.

I started thinking about this while building OneLess Pomodoro.

I wanted the timer to stay useful after the first session, not just look useful on the first visit. So actual focused minutes still count even when a planned session ends early, and things like reports, tasks, presets, and different focus rhythms are part of the same experience rather than something you have to unlock just to keep using it.

I m curious about the opposite side of this:

What s the smallest limit or restriction that has made you abandon a tool you otherwise liked?

Was it a daily cap, signup requirement, locked history, export limits, number of projects, or something else?

I d especially like to hear about tools that were genuinely good right up until that moment.

If you stop a 50-minute focus session at 32 minutes, what should count?

I ve been thinking about this while building OneLess Pomodoro.

Say you set a 50-minute focus session, but stop after 32 minutes.

Would you rather see:

  • an incomplete session

  • 32 minutes of actual focus

  • both

I ended up building OneLess around the second idea: the time you actually focused still counts, even if the planned session wasn t completed.

That decision also shaped the reports and goals they re based on real focus and break time rather than completed-session counts.

I launched it on Product Hunt this week:

I m curious how other people think about this.

When you look back at your productivity, do completed sessions matter to you, or is total focused time the more useful number?

What makes you come back to a focus timer?

OneLess Pomodoro is launching tomorrow, and before the launch I wanted to ask one simple question.

There are already many Pomodoro and focus timers, but I ve noticed that starting a timer once is very different from actually coming back to use it regularly.

While building OneLess, I focused on a few things I personally wanted:

  • tracking actual focus time instead of completed session counts

  • flexible focus and break lengths

  • daily and weekly progress reports

  • presets for different routines

  • visual scenes and ambient sounds to make focusing feel less mechanical

But I m curious about what matters to other people.

What makes you return to the same focus timer regularly?

Is it simplicity, reports, streaks, customization, sound, visual atmosphere, goals or something else?

I d love to hear what actually matters in real use.
