Wearable companion apps
We develop companion apps for smartwatches (Apple Watch, Wear OS): notifications, quick actions, key data and fitness scenarios right on the wrist as an addition to the main app. Honestly upfront: a watch app is, as a rule, a COMPANION to the phone app, not a standalone product; watches have strict limitations (a tiny screen, battery, usually a phone nearby is needed); and this suits NOT every product — for fitness, notifications and quick actions watches are excellent, for complex scenarios — not. We will honestly assess whether you need a watch companion at all.
Wearable companion apps — overview

Wearable companion apps is developing a version of your app for smartwatches (Apple Watch on watchOS, Wear OS watches) in addition to the main mobile app: showing notifications, one-tap quick actions, key data 'on the wrist', fitness/health scenarios (workouts, heart rate, steps), complications on the watch face. Honestly about the role, this is key: a watch app is almost always a COMPANION to the phone one, not a replacement. It extends the main product onto the wrist rather than working on its own (though some scenarios can be standalone). Honestly about watch limitations, this matters: a tiny screen (only the essentials, not a full interface), limited battery and compute, many scenarios require a phone nearby. So not everything is moved to the watch, only what is genuinely useful 'on the go'. Honestly about feasibility: a watch companion is not justified for everyone. It suits fitness/health, notifications, quick actions, tracking excellently; but if your product has no short 'on the wrist' scenarios, separate watch development may not pay off — we will honestly say so before starting. Honestly about the effect and scope: this is separate real development (its own platform, design, device testing) that improves the experience and loyalty of a suitable audience but does NOT guarantee engagement or sales growth. Honestly about access: the main app/code and test devices are needed. An important boundary: this is wearable companions; tablets — 863, foldables — 864, base development — 833+. Picture this: instead of 'everything only on the phone' — the key and quick right on the watch, where apt. The base price starts from 40,000 ₽ (depends on the platform and scenarios).
Problems we solve
- Users need quick actions/data on the wrist, but there are none.
- Notifications and fitness scenarios do not reach smartwatches.
- The temptation to move too much to the watch (screen/battery can't handle it).
- It is unclear whether separate watch development pays off.

FAQ
Does a watch app work on its own?
As a rule — no, and that is honest: a watch app is almost always a companion to the phone one, extending it onto the wrist, not a standalone product. Some scenarios can be standalone, but many require a phone nearby. We honestly design the companion for real 'on the wrist' scenarios rather than promise a full app on the watch.
Can the app's entire functionality be moved to the watch?
No — and it should not be. The watch has a tiny screen, limited battery and resources. Only the most useful 'on the go' is moved to the wrist: notifications, quick actions, key data, fitness. Trying to cram the whole interface makes it inconvenient and drains the battery. We honestly select the scenarios that genuinely work on the watch.
Does my app definitely need a watch companion?
Not every one, and we will honestly assess it before starting. Watches suit fitness/health, notifications, quick actions and tracking excellently. But if your product has no short 'on the wrist' scenarios, separate watch development may not pay off. We will say directly whether a watch companion is justified for you rather than take it on for the volume.
