Intervalla launched with a pretty clear scope: solid interval timing, a clean interface, Bluetooth heart rate support, and saved presets.

That part is working well. Now we're moving into the next set of improvements.

Some of these features are already being built. Others are a little further out, but they are on the list because they would make the app meaningfully better for real training, not just more feature-rich on paper.

Next Up

These are the features closest to shipping.

HR Live View

This mode puts heart rate front and center while keeping the timer in a supporting role.

It is meant for workouts where the clock matters, but your main focus is staying in the right effort range. Think active recovery, easier conditioning, or steady sessions where you care more about staying under control than chasing splits.

Screen Lock

This one is simple, but useful.

Sweaty hands, sleeves, and accidental taps are a real thing during workouts. Screen lock will disable touch input until you deliberately unlock it, so you do not end up pausing or ending a session by mistake.

Better Workout Summary

Right now, finishing a workout is a little too abrupt.

We're improving the summary screen so it gives you a clearer snapshot of what you just did, including duration, rounds, interval setup, and heart rate data when a monitor is connected.

What We're Exploring After That

A few bigger ideas are also taking shape.

Heart Rate Zone Mode

This would let you set an upper and lower heart rate boundary and get nudged when you drift outside it.

That matters for workouts where the target is physiological, not just time-based. Things like zone-based training, 4x4 intervals, aerobic work, and controlled recovery sessions all fit that pattern.

Workout Chaining

A lot of sessions are really two or three blocks stitched together.

Maybe you want an AMRAP, then a short rest, then a Tabata finisher. Maybe you want a warmup block followed by a 4x4 interval set. Workout chaining would let you queue that up in advance instead of rebuilding the timer between pieces.

This would make it easy to share a workout or preset with someone else.

Generate a QR code, have them scan it, and they get the same interval structure on their device. That is handy for coaches, training partners, or anyone who is tired of sending screenshots back and forth.

Group Workouts

This is the bigger one.

The idea is to let one device act as the master timer while other devices follow along in sync. For classes, small group sessions, or coached workouts, that would make starts and transitions much cleaner.

Workout History

We also keep hearing requests for persistent workout history.

This is still in the exploration phase, but we understand the appeal. Being able to look back at how often you trained, what formats you used, and how your heart rate responded over time could be genuinely useful if we implement it in a clean way.

How We Decide What Comes Next

We are not trying to build the longest roadmap page possible.

We would rather ship a smaller number of features that clearly improve the workout experience than pile on extras that sound impressive but do not get used. In practice, that means we listen closely to what people ask for, but we also weigh how often a feature would matter during actual training.

If there is something you want from Intervalla, let us know through the contact page. A lot of the roadmap comes from those conversations.

You Can Use It Right Now

Everything above is being built on top of the version that is already live.
