The best running app if you use both Apple Watch and Garmin
If you own both an Apple Watch and a Garmin, the best training app is one that syncs with each and keeps a single, continuous plan no matter which one you wore today. RunV connects to Garmin, Apple Watch and Wear OS at once, so a Garmin on long-run day and an Apple Watch the rest of the week feed the same coaching engine. Here's why multi-device support matters and what to check before you commit.
Why runners end up with two watches
It's more common than it sounds: a Garmin for its GPS and battery on long runs, an Apple Watch for everyday wear, notifications and gym work. Or a household that shares devices, or someone mid-switch between ecosystems. The problem is that most training apps assume one watch — connect the other and your data fragments across two silos, and the plan can't see the full picture.
What 'works with both' really requires
Two things. First, genuine sync with each platform — Garmin Connect and Apple Health/HealthKit — not a lowest-common-denominator import. Second, and more important, one unified plan on the app's side: every run, whichever watch recorded it, has to land in the same training history so load, pace and heart-rate trends are continuous. Without that, switching watches quietly resets the coaching.
What to look for
- Native support for both Garmin and Apple Watch, plus Wear OS if you might switch again.
- One continuous training history — runs from either device merge into a single load and fitness trend.
- Structured workouts pushed to whichever watch you're wearing, not just activity import.
- No double-counting — the app dedupes if a run somehow arrives from two sources.
How RunV handles multiple devices
RunV syncs with Garmin, Apple Watch and Wear OS simultaneously and folds everything into one adaptive plan. Wear the Garmin for Sunday's long run and the Apple Watch for Tuesday's easy miles, and the engine still sees a single, coherent block — it rebuilds overnight from all of it. You never have to pick a 'main' watch or reconnect when you switch.
The upshot
For a two-watch runner, sync breadth isn't a nice-to-have — it's the whole thing. An app that treats your devices as one data stream gives you an accurate plan; one that doesn't gives you two half-pictures. Match the app to how you actually train, not to a single device it assumes you own.
FAQ
- Can one app sync with both Apple Watch and Garmin?
- Yes. RunV connects to Garmin, Apple Watch and Wear OS at the same time and merges every run into one training history, so switching watches doesn't split your data or reset the plan.
- Will my runs get double-counted if I use two watches?
- Not if the app dedupes properly. RunV folds activity from all connected devices into a single load and fitness trend, so a run recorded on one watch isn't counted twice.
- Do I have to pick a main watch?
- No. You can wear whichever device suits the session — a Garmin for long runs, an Apple Watch day-to-day — and the plan stays continuous across both.
