Beta: free for 30 days

The app works fully and for free for the first 30 days after you first open it. After that you can buy a one-time unlock code below. No subscription.

Runs on elapsed time, not counted ticks, so it cannot drift or lock up. Always saves as HIIT with the correct EMOM, AMRAP or Tabata type in Garmin Connect.

  • EMOM: interval length and rounds
  • AMRAP: time cap, count rounds with the buttons
  • Tabata: 20/10 x 8 or your own numbers
  • Custom: work, rest, rounds, sets, rest between sets
  • Big countdown, phase colour, round/set count, elapsed time, heart rate
  • Remembers your last settings per mode

How to use it

Open Interval Timer from the watch's app menu.

Controls: START pauses/resumes. BACK opens the menu (resume, save, discard). UP/DOWN change rounds in AMRAP. On watches without UP/DOWN, tap the upper or lower half of the screen.

Manual

Interval Timer: user manual

What it does

Interval Timer runs EMOM, AMRAP, Tabata and custom interval workouts. It reads time from the watch clock, so it does not drift, and saves the session to Garmin Connect as a HIIT activity with a lap per round.

Requirements and supported watches

Needs Connect IQ 3.3.0+ and the Connect IQ or Garmin Connect phone app. Supported watches:

  • Round AMOLED: epix 2 and epix Pro 2, fēnix 8, E, Forerunner 165, 265, 570, 965, 970, Instinct 3 AMOLED, Crossover AMOLED, Venu 2, 3, 4, vivoactive 5, 6.

Installation

In the Connect IQ app on your phone (or Garmin Connect, then the Connect IQ Store) find "Interval Timer" by Dialforge, tap Install and sync the watch. Open it from the apps list: press START on the watch face, then pick Interval Timer.

First launch

The start screen shows the app name, "Press START" and the free beta days left. START (or a tap) opens the setup menu: Start, Mode and the values of that mode. Values are remembered per mode. The 30-day free beta starts the first time you open it.

Controls

Watches with buttons (START, UP, DOWN, BACK)

  • Setup: START opens the menu. UP and DOWN scroll, START on a value raises it one step and wraps to the minimum after the maximum. Choose Start to begin.
  • Workout: START pauses and resumes. BACK opens Resume, Save, Discard (Discard asks twice).
  • AMRAP: UP adds a round, DOWN removes one.

Touch watches (tap, hold, swipe)

  • Setup: tap opens the menu, tap a value to raise it a step.
  • Workout: tap pauses and resumes. Swipes do nothing.
  • AMRAP without UP and DOWN buttons: tap the upper half of the screen for +1 round, the lower half for -1. Pause then goes through BACK or holding the menu button.

Settings

Phone: Connect IQ app, Interval Timer, Settings (the unlock code fields are there too).

On the watch, inside the app:

  • Mode: EMOM, AMRAP, Tabata or Custom.
  • EMOM: interval 0:15 to 10:00, rounds 1 to 60.
  • AMRAP: time cap 1:00 to 60:00.
  • Tabata: work and rest 5 to 120 s, rounds 1 to 30.
  • Custom: work 5 to 600 s, rest 0 to 300 s, rounds 1 to 30, sets 1 to 10, rest between sets 0 to 600 s.

License

  • Free beta: 30 days from the first launch, everything works.
  • Price: 5.99 EUR once at dialforge.dev, no subscription. The 8-character code is tied to your watch's UID.
  • Where to enter it: phone, Connect IQ app, Interval Timer, Settings. Read the UID in "Watch UID (needed to buy a code)", buy the code, then type it into "Unlock code from dialforge.dev". The end-of-beta screen on the watch shows the UID too.
  • After the beta without a code: an end-of-beta screen with the UID replaces the app. Enter the code, then open it again. New watch? Write to us and the code moves for free.

Privacy and permissions

Permissions:

  • Activity recording: saves the session to Garmin Connect.
  • Extra FIT fields: adds the app's values to the saved activity.
  • Sensors: reads heart rate from the watch to show it during a workout.

No internet use. Data stays on the watch and in the activities you save.

Troubleshooting

The code does not work. Check that the UID you bought for matches "Watch UID (needed to buy a code)" and type all 8 characters (case is ignored, no 0, O, 1 or I). A code for another app does not fit. Sync, then reopen.

Where is my workout? Choose Save in the stop menu: it lands in Garmin Connect as HIIT (EMOM, AMRAP or Tabata type) with a lap per round.

No heart rate on screen. It shows once the watch has a reading. Wear it snug above the wrist bone.

Does pausing break the timing? No, phases come from elapsed time, so pause and resume keep time and laps right.
