32-Bit vs 64-Bit Apps on Tablets: Compatibility

What 32-bit and 64-bit mean

The terms 32-bit and 64-bit describe the width of a processor's data paths and the size of memory addresses it can handle. A 64-bit processor can address significantly more memory and can process larger data chunks in a single operation. This is why 64-bit operating systems and apps are now the standard on tablets.

Tablets are a type of computer, as defined by ENERGY STAR, with touch screens and long battery life. Like desktops and laptops, their performance depends on the processor and the software that runs on it. The Android operating system, for example, is built from the Android Open Source Project (AOSP), which provides the foundation for many tablet models.

When you install an app, the app must be compiled for the processor architecture and operating system. A 32-bit app is designed to run on a 32-bit processor or in a 32-bit compatibility mode. A 64-bit app requires a 64-bit processor and a 64-bit operating system. Most modern tablets ship with 64-bit processors, but some older or budget models may still be 32-bit only.

How operating systems handle both

Operating systems like Android and Windows can support both 32-bit and 64-bit apps, but the level of support varies by version and vendor. For instance, some Android versions include a compatibility layer that lets 32-bit apps run on 64-bit hardware. However, as the ecosystem moves forward, many manufacturers and app stores have begun to phase out 32-bit support entirely.

The decision to drop 32-bit support often comes from the need to improve security, performance, and battery life. 64-bit apps can use more memory and are generally better optimized. The AOSP source page indicates that Android continues to evolve, and each new release may change system requirements. It's a good idea to check the OS version and update policy of any tablet you consider.

For Windows tablets, the transition to 64-bit has been complete for years, and most Windows apps are now 64-bit. On the Apple side, iPadOS has required 64-bit apps since iOS 11, so all current iPads run only 64-bit apps. This is worth keeping in mind when you shop for a tablet.

Checking app compatibility

To see whether a tablet can run a specific app, check the app's requirements in the official app store. Look for the minimum operating system version and processor architecture listed. If the app says "64-bit" or "requires a 64-bit processor," you know a 64-bit tablet is needed.

You can also check your tablet's system information to see its OS version and processor model. On Android, go to Settings, then About Tablet. On Windows, type "System Information" in the search box. On iPadOS, go to Settings, General, About.

If you are unsure about a legacy app that was designed years ago, it may still be 32-bit. Many older Android apps were never updated, and some might not run on the latest 64-bit-only operating systems. This is less of a problem on Apple tablets because they have required 64-bit for a long time.

• Use the app store's search filters to see if the app is listed as 64-bit.
• Check the app's release notes for notes about 32-bit or 64-bit support.
• Contact the app developer if the requirements are unclear.

Why some apps are still 32-bit

Legacy apps are often 32-bit because they were written for older hardware. Developers may not have updated them, either because the app is abandoned or because the user base is small. In some cases, the app's functionality depends on old libraries that are not available in 64-bit versions.

For business or specialized applications, you might encounter 32-bit software that is still in use. This is especially true in healthcare, industrial, and logistics settings. If you rely on such apps, verify that your chosen tablet still offers compatibility. Consider consulting our guide to Android tablets or Windows tablets to see which models are likely to stay up to date.

The USB Implementers Forum describes how USB has evolved to support more devices and power delivery, and tablets are a key part of that ecosystem. As USB standards advance, so do the processors and operating systems that tablets use. This is another reason why older app formats can become obsolete.

What to look for in a tablet

For the broadest app compatibility, choose a tablet with a 64-bit processor and a recent operating system. Most tablets produced in the last few years meet this requirement. Even budget models now typically use 64-bit processors, though they may have less memory and storage.

Pay attention to the OS version and the update policy. A tablet that receives regular updates is more likely to support new 64-bit apps and security patches. You can read about tablet OS updates to understand how long a device will stay current.

Also consider the processor architecture. Most Android tablets use ARM-based chips, while Windows tablets may use ARM or x86. The difference affects app compatibility with certain Windows software. See our comparison of ARM vs x86 for more details.

How to choose a tablet for your needs

If you want to run the latest productivity and creative apps, a 64-bit tablet is essentially a requirement. This includes most apps on the Apple App Store and Google Play Store. For gaming and memory-intensive work, a 64-bit processor with enough RAM is even more important. Read our guide to tablet RAM to understand how much memory you need.

If you are replacing an older tablet and need to keep using a specific legacy app, take the time to confirm that the app works on the new tablet's OS. You can also look for tablets that offer a desktop mode, such as some Android and Windows devices, which may provide extra compatibility for older software. Our desktop mode article explains this feature.

The best way to ensure a smooth experience is to pick a well-known model from a major manufacturer. Compare current options across Apple, Android, and Windows tablets using our buying guides: best Apple tablets, best Android tablets, and best Windows tablets. These guides focus on specs and features that affect app support.

Questions

Can a 64-bit tablet run 32-bit apps?

It depends on the operating system and manufacturer. Some Android versions include a compatibility layer for 32-bit apps, but many recent Android releases have dropped this support. Windows tablets can often run 32-bit apps in a compatibility mode, while iPads have required 64-bit apps since iOS 11 and do not run 32-bit apps at all.

How can I tell if my tablet is 32-bit or 64-bit?

Check your tablet's processor model and operating system version in the Settings app. You can also look up the processor name on the manufacturer's website. Most processors made after 2017 are 64-bit capable.

Are all new tablets 64-bit?

Yes, virtually all new tablets released in recent years use 64-bit processors. Even budget models now come with 64-bit chips, though their memory and storage may be smaller.

Do 64-bit apps consume more battery or memory?

They can use more memory because they are designed to take advantage of larger address spaces, but they are often more efficient due to better optimization. The impact on battery life is usually minimal and depends on the app's features.

What should I do if a critical app is only 32-bit?

Before buying a new tablet, verify that the app runs on the target operating system version. You might need to choose a Windows tablet for broad compatibility, or look for an older Android tablet that still supports 32-bit apps. Alternatively, search for a 64-bit replacement app for the same task.
