How To Update Strelok Pro May 2026

This is the method used for 95% of users who have a standard internet connection and a modern device.

Strelok Pro is widely considered the gold standard for ballistic calculators on mobile devices. Used by military snipers, competitive long-range shooters, and hunters, its power lies in its massive database of reticles, bullets, and custom drag models. However, like any sophisticated software, it requires regular updates to remain accurate.

If your data seems off, new ammunition isn’t appearing, or you’ve upgraded your phone’s operating system, you need to know exactly how to update Strelok Pro.

This guide covers three distinct update methods:


For a user asking "How do I update Strelok Pro right now?":


"My reticles are missing!"

"The app crashes after the update."

"I can't find the update."

Updating Strelok Pro has become more complex recently because it is no longer available on the official Google Play Store or Apple App Store due to international sanctions. However, the developer, Igor Borisov, continues to release updates through alternative channels. How to Update Strelok Pro on Android

Since the app was removed from mainstream stores, you must use alternative app markets or manual APK installations to receive updates.

Option 1: Huawei AppGallery (Recommended)This is currently the most reliable way to get official updates. You do not need a Huawei phone; the Huawei AppGallery can be installed on any Android device.

Install AppGallery: Download and install the AppGallery APK from Huawei's official site.

Register an Account: You may need to use a VPN (e.g., set to UAE/Dubai) if your region blocks the app.

Purchase/Update: You will likely need to purchase the app again on this platform, as licenses from Google Play do not transfer.

Option 2: Samsung Galaxy StoreIf you use a Samsung device, check the Samsung Galaxy Store. While it was removed in some regions, it may still appear in others.

Option 3: Manual APK UpdateYou can download the latest APK directly from third-party sites like Aptoide or Uptodown, but this is done at your own risk. how to update strelok pro

Option 4: RuStoreFor users in specific regions, the app is available on RuStore, though licenses are again tied to that specific store. How to Update Strelok Pro on iOS

Apple's "walled garden" makes updates much harder once an app is delisted.

Prevent Deletion: Go to Settings > App Store and turn off "Offload Unused Apps" to prevent your iPhone from automatically deleting the app to save space.

Reinstalling/Updating via iMazing: If you previously purchased the app, you can sometimes "update" or reinstall it using the iMazing software on a PC or Mac. Connect your iPhone to your computer. Use the "Manage Apps" section in iMazing. Sign in with the Apple ID used for the original purchase.

Download the app to the iMazing library and then install it to your device. Transferring Your Data (Rifles and Cartridges)

Title: The Ghost in the Firmware Subtitle: A Step-by-Step Guide to Updating Strelok Pro

Part 1: The Obsolescence

Alexei stared at the rain streaking down the window of his Moscow apartment. On the table in front of him lay a brand-new Vector Optics scope, a bipod that cost more than his first car, and a ballistic calculator that was three hours out of date.

His phone screen glowed with the familiar grid of Strelok Pro. He had used this app for five years. It had accounted for the Coriolis effect on a 1,200-meter shot in the Caucasus. It had saved his data when his tablet was shot out of his hand in Donbas. Strelok Pro wasn’t just software; it was a talisman.

But tonight, the data was wrong. The 6.5 Creedmoor bullet drop was off by 0.3 mils. The humidity algorithms were glitching. A pop-up appeared: “Database outdated. Update required.”

The problem was that the original developer, Igor Borisov, had vanished. Some said he was in hiding; others said he had been sanctioned. The app was no longer in the official stores. To update Strelok Pro, Alexei couldn't use the Play Store. He had to go into the Sidemodo.

Part 2: The Backup

Alexei plugged his phone into a ruggedized laptop. He knew the first rule of ballistic software: Never update the working version. If the new drag coefficient (G7) corrupted the file, his next shot would be a miss by forty meters.

He navigated to the hidden folder: Android/data/com.igorsoft.strelokpro/files/. This is the method used for 95% of

He copied the user_data.bin file—containing twelve custom ammunition profiles—to a cold storage USB. Then he copied it to a second USB. Then he printed the QR codes for his custom Hornady loads onto waterproof paper.

"Trust, but verify," he whispered, channeling a dead proverb.

Part 3: The Source

The official site was dead. Igor’s Telegram channel, however, was alive. In the pinned message of the "Strelok Survivors" group, a user named Ruslan_762 had posted a link: strelok_update_v6.04_hotfix.apk.

Alexei scanned the hash code. He compared it to the checksum posted by three different moderators. They matched. No rootkit. No spyware.

He downloaded the file, air-gapped the laptop from the hotel Wi-Fi, and transferred the APK via a sacrificial USB drive—the kind you throw in the fireplace after using.

Part 4: The Injection

He couldn’t install it directly. Android 14 blocked "unofficial sources." He had to unlock the bootloader, a process that voided his warranty and made him feel like a bomb disposal expert.

He enabled Developer Options by tapping the build number seven times. He turned off Automatic System Updates. He toggled OEM Unlocking.

The phone rebooted into fastboot mode. A black screen with white text. He plugged in the command: fastboot flashing unlock.

The phone wiped itself. Everything was gone. The photos of his daughter. The maps. The music. Only the USB stick with the user_data.bin remained.

He sideloaded the new Strelok Pro APK using ADB (Android Debug Bridge). The terminal scrolled green text: Success.

Part 5: The Calibration

The new app opened. The interface was different—starker, faster. The G7 BC database had been updated with bullets manufactured after the war started.

He imported his old user_data.bin. The profiles loaded. But the scope height needed re-zeroing. For a user asking "How do I update Strelok Pro right now

He walked to the window. Across the square, 347 meters away, was a rusty fire escape ladder. He knew the exact width of the third rung: 12 inches.

He input the distance: 347m. Input the height over bore: 3.2 inches. Input the wind: 4 mph, left to right, gusting.

Strelok Pro calculated: Adjust 2.1 mils up. Hold 0.4 mils left.

He didn’t fire a bullet. He just visualized the reticle. The old ghost data would have told him 1.8 mils. The new data felt true.

Part 6: The Verification

The final step was the "Tall Target Test." He drove three hours north to a gravel pit at dawn. He taped a piece of white cardboard to a tree. Exactly 100 meters away, he measured a vertical line.

He fired three shots at the bottom mark. Then he dialed the scope up exactly 10 mils based on Strelok Pro’s new calculation. He fired three shots at the top.

He walked to the cardboard. The bottom group was tight. The top group was exactly 100 centimeters higher—exactly 10 mils of elevation.

The update was successful.

He deleted the installer from the laptop. He wiped the ADB history. He uninstalled the developer tools. He buried the sacrificial USB in the gravel.

Strelok Pro glowed on his phone, calibrated to the current atmosphere, the current spin drift, and the current reality.

He looked at the app. The ghost of Igor Borisov lived on.

Database updated. Ready for solution.

Moral of the story: A ballistic calculator is only as good as its last update. In a world where software devolves into abandonware, the shooter who knows how to side-load, verify hashes, and field-verify data is the one who walks home. Keep your cold storage safe, keep your wits sharp, and always—always—double the checksum.


Even if the app version is up to date, the internal library of bullets and reticles may be stale. This is the most critical update for accuracy.
