What is the best budget smartwatch in the UK right now?

If you鈥檙e searching for the best budget smartwatch UK, the most reliable all-round choice in 2024 is the Ruziza Varia ProFit: it delivers a bright AMOLED screen, strong everyday health tracking, and long battery life for under 拢100. Based on our testing in UK day-to-day use (commutes, gym sessions, and outdoor walks in mixed weather), it鈥檚 the best balance of price, comfort, and practical features.

That said, 鈥渂est鈥?depends on what you value most. Therefore, below we鈥檒l compare the top budget options available in the UK and explain what you can realistically expect under 拢100鈥攚ithout marketing fluff.

How did we test budget smartwatches in UK conditions?

At Ruziza Varia, we tested popular budget models the way most people in the UK actually use them. In other words, we focused on everyday reliability rather than lab-only numbers.

• Battery and charging: tracked across a normal week of notifications, workouts and sleep tracking.
• Screen readability: checked indoors, outdoors, and in bright daylight (yes, even in the brief UK sunshine).
• Health and fitness: compared heart rate and SpO2 trend consistency across walking, running and gym sessions.
• Comfort and durability: assessed for all-day wear, rain resistance, and strap comfort during workouts.
• Phone compatibility: tested with both iOS and Android for notifications, app stability and syncing.

Note: These devices are not medical equipment. If you have symptoms or concerns, follow UK medical advice and speak to a qualified healthcare professional.

What should you expect from a smartwatch under 拢100 in the UK?

In 2024, a smartwatch under 拢100 in the UK can genuinely feel 鈥減remium鈥?in daily use. As a result, you no longer have to accept a dim screen, poor battery life, and unreliable sensors just because you鈥檙e shopping on a budget.

What features do the best cheap smartwatches in the UK include?

• AMOLED displays: Increasingly common, with better contrast for quick checks on the go.
• 24/7 health tracking: Heart rate, SpO2, stress estimates, and sleep stage breakdowns are now standard on many models.
• Strong battery life: 7鈥?4 days is realistic because most budget watches run lightweight software rather than power-hungry platforms.
• Sports modes: Often 80鈥?00+ modes, although the quality of metrics varies by brand.

What are the compromises with budget smartwatches?

However, there are still trade-offs at this price point. Typically, the biggest compromises affect 鈥渘ice-to-have鈥?smart features rather than the basics.

• App ecosystem limitations: You generally can鈥檛 install full third-party apps like Spotify, banking apps, or advanced training tools directly on the watch.
• No medically certified features: ECG and regulatory-grade AFib detection are uncommon under 拢100 in the UK market.
• Materials: You鈥檒l usually get polymer and aluminium rather than sapphire glass, titanium or stainless steel builds.
• Contactless payments: NFC payments (e.g., Google Wallet/Apple Pay) are often missing, which matters if you want to tap in on TfL without your phone.
• Built-in GPS: Many budget models rely on connected phone GPS, which is fine for most users but not ideal for phone-free runs.

"Prioritise the features you鈥檒l use daily. If you mainly want notifications, steps, sleep trends and a long battery, a good 拢60鈥撀?00 watch can be genuinely excellent." 鈥?Ruziza Varia Tech Team

Next: In the sections below, we鈥檒l break down the questions UK shoppers ask most before buying, so you can confidently choose the right model for your phone and lifestyle.

Is a budget smartwatch good enough for fitness tracking in the UK?

Yes鈥攊f your goal is everyday fitness tracking like steps, workouts, heart rate trends and sleep routines, a good budget smartwatch is usually more than enough. In fact, many sub-拢100 watches now provide consistent trend data that helps you build habits.

However, if you need precise running dynamics, advanced training load metrics, or medical-grade sensors, you鈥檒l likely need to increase your budget. Additionally, for the most accurate GPS routes, choose built-in GPS or expect to carry your phone.

Do cheap smartwatches work with iPhone in the UK?

Most cheap smartwatches in the UK will pair with iPhone, but the experience can be more limited than on Android. For example, you may receive notifications reliably, yet you might not be able to reply to messages or use deeper integrations depending on the watch and app.

Therefore, if you鈥檙e on iOS, prioritise models with a well-reviewed iPhone companion app and strong notification stability.

Do budget smartwatches have GPS and contactless payments in the UK?

Often, no. Many budget models rely on connected phone GPS rather than having GPS built in, and contactless payments are still rare under 拢100. As a result, if you want to leave your phone at home and pay on the go (including tapping in on TfL), you may need to spend more than budget pricing.
