When it comes to measuring change over time -whether in wellbeing, learning, behaviour, or attitudes -many survey tools fall short. That’s because most platforms treat surveys as one-off events. But real impact happens across time. If you’re running a programme with a baseline, midline, and endline survey, you already know how messy it can get.

Do you copy and paste the same questions into three different surveys? How do you track whether someone’s answer actually changed - or if you’re just comparing apples and oranges?

That’s exactly why we built Interval Logic.

What is Interval Logic?

Interval Logic lets you customise how a question appears depending on the stage of the programme - baseline, midline, or endline - while still keeping all responses linked for longitudinal analysis.

Here’s what you can do:

• Show, hide, or reword a question based on the survey interval
• Tailor the language of questions as participants progress, without breaking the data connection
• Automatically link responses from the same individual across different stages for cleaner analysis

Why It Matters

Without a feature like Interval Logic, most teams end up doing one of two things:

• Duplicating questions across separate surveys and trying to stitch together the data manually (error-prone and time-consuming)
• Asking overly generic questions that don’t account for someone’s progress through the programme

Both approaches can lead to messy data, lost insights, or extra work for your team.

With Interval Logic, you design your survey once—and let the platform handle the rest. Whether someone is just starting or halfway through a programme, their experience feels seamless. And when it’s time to analyse results? Their answers are already aligned and ready to go.

Designed for Real-World Complexity

This isn’t just about convenience - it’s about accuracy. Mid-programme dips, shifts in self-perception, and non-linear progress all affect how people respond. Interval Logic allows you to respect that nuance by adjusting the framing of questions without compromising the integrity of your data.

Whether you're running parenting workshops, wellbeing programmes, training interventions, or social impact studies, this feature makes tracking change both smarter and simpler.

Final Thought

If your work is about helping people change, grow, or improve, your survey platform should support that journey - not get in the way of it. Interval Logic is our way of making sure your data reflects real progress, across real time, with real people. Get Started
