Impetus now has built-in support for the Pebble smartwatch.

Pebble & Impetus

To control Impetus from Pebble you need the Impetus watch app. The watch app can be installed on the watch from Impetus in Settings – Accessories.

You can start the timer from the watch app or from Impetus, either way is fine. The two apps will be in sync while the timer runs. The phone or tablet doesn’t have to be unlocked to start the timer as the watch app can communicate with Impetus also when the display is off. The currently loaded preset will always be used by the watch app, so select the preset in advance.

Pebble’s small display shows the following information:

  • Current interval name
  • Current round
  • Current remaining time
  • Selected preset name

The timer can be started, paused and reset from the watch app. The watch will vibrate and briefly turn on the backlight on interval changes.

The Pebble app is still somewhat a work-in-progress, so future changes may be possible.

Changes in version 2.0

It’s time for a bigger version bump! Version 2.0 introduces a lot of changes in how the app looks and functions. Some changes are quite major, some more subtle. Here’s a little tour of what’s new.


The save button has gone the way of the dodo, as all changes to a preset are now automatically saved. If you want to create a totally new version of an existing preset you can use the Copy This Preset option found in the app menu. This will make a duplicate of the current preset.

Super quick simple preset editing

When editing a simple preset just tap on the interval and the spinner wheel opens right in the edit screen.


Advanced editing

The advanced preset edit list is the same as before but the detail view now opens all sets and timers in a tabbed view. Just swipe between pages to edit all the necessary details on one page.


Accented time

The time displays are now accented to give more weight to the significant digits.


Real-world pre-configured presets

All fresh installs of Impetus will now have a collection of ready-made presets featuring different interval workouts from around the world. Ready for training or to be used as a base for your own presets.


Tired of fiddling around with the mobile phone while training? Here’s some options for remote controlling the timer.

Headset control

You can now enable headset control in settings to pause and resume a running timer with the headset button. Note that the remote cannot be used to select a preset or to start the timer. The app itself needs to be used for that. This feature can be enabled in Settings – Accessories.

Pebble smartwatch (BETA)

You can install a Pebble watch app directly from Impetus and remotely control the app with it. The timer can currently be started, paused and reset remotely using the watch app. The watch app will also display the current interval description and round number, and vibrate on interval changes. The used preset needs to be selected using the Impetus app itself. The watch app can control the timer also when the phone display is off. Pebble integration can be enabled in Settings – Accessories.

Please note that this feature is still somewhat experimental and does not represent the final implementation.

Overtime count-up

Want to know how much more time you would have needed to crunch that last round? You can now have an count-up timer that starts after the whole session is finished. The timer will run indefinitely until it’s reset. This feature can be enabled in Settings – Miscellaneous.

Rich notifications

A running timer can now be paused, resumed and reset from the device’s notification tray on devices with Android 4.1 and up.

Those are pretty much all the more major changes in 2.0. Otherwise there’s been all kinds of tweaks on the UI and the overall reliability of the app. There’s a long list of features still waiting, so watch this space for future updates!
