🔢 CALCULATOR PRO+ — THE CALCULATOR THAT KEEPS YOUR PRIVATE LIFE PRIVATE Calculator Pro+ looks and works like a normal calculator. Enter your secret PIN on the keypad and unlock a completely hidden world — private SMS, in-app calls, chats and media, invisible to everyone else. ━━━━━━━━━━━━━━━━━━━━━━━━━━ 🧮 HIDDEN INSIDE A REAL CALCULATOR Dial your secret PIN on the keypad to open your private vault — no swipes, no obvious unlock screens. To everyone else, it's just a calculator that really calculates. ━━━━━━━━━━━━━━━━━━━━━━━━━━ 🔒 MULTI-LAYER SECURITY • PIN lock & fingerprint unlock • Fake PIN — decoy shows empty inbox to anyone who asks • Auto-lock on screen off or idle timer • Shake-to-close for instant privacy in public ━━━━━━━━━━━━━━━━━━━━━━━━━━ 💬 PRIVATE MESSAGING — TWO WAYS ── Free App-to-App Messaging ── When both sides use Calculator Pro+, messages travel over the app's own private network — no SMS, no carrier charges. Free over Wi-Fi or mobile data. • Smart reply suggestions • Disappearing messages — 1 hour to 3 months • Delete for Everyone — both sides, instantly ── Hide Normal SMS & MMS (with our free AdvanceSMS app) ── Android only lets your default SMS app hide text messages, so Calculator Pro+ works together with our free companion app, AdvanceSMS. Set AdvanceSMS as your default SMS app once — after that, messages from your private contacts go straight into the Calculator Pro+ vault and never show up in your phone's normal inbox. Replies go out as normal SMS, with no sign you are using a hidden app. ━━━━━━━━━━━━━━━━━━━━━━━━━━ 📞 IN-APP VOICE & VIDEO CALLS Voice and video calls between Calculator Pro+ users over the internet — no carrier minutes, no native call log trace, no SIM required. Full-screen incoming call even on a locked screen. Bluetooth and speakerphone supported. ━━━━━━━━━━━━━━━━━━━━━━━━━━ 📵 SMS & CALL BLOCKER Block unwanted contacts silently through the app. All blocked activity logged privately inside your vault. ━━━━━━━━━━━━━━━━━━━━━━━━━━ ☁️ GOOGLE DRIVE BACKUP & RESTORE Auto-backup on a daily, weekly or monthly schedule. Restore everything in one tap when you switch phones or reinstall the app. Local backup to device storage also supported. ━━━━━━━━━━━━━━━━━━━━━━━━━━ 📱 VIRTUAL NUMBERS Buy a temporary number inside the app and contact anyone without revealing your real phone number. ━━━━━━━━━━━━━━━━━━━━━━━━━━ 🎨 FULL CUSTOMISATION Wallpaper themes, colour themes, dark mode, custom bubble colours, fonts, per-contact ringtones, wallpapers and 300+ emoji. ━━━━━━━━━━━━━━━━━━━━━━━━━━ ✅ WHY CALCULATOR PRO+ ✔ Real working calculator — zero suspicion ✔ Fake PIN decoy inbox ✔ Free app-to-app internet messaging — no carrier charges ✔ VoIP calls — no native call log trace ✔ Disappearing messages & Delete for Everyone ✔ Normal SMS/MMS hidden via free AdvanceSMS companion app ✔ Google Drive auto-backup & one-tap restore ✔ Virtual numbers to mask your real phone number ━━━━━━━━━━━━━━━━━━━━━━━━━━ ⭐ UPGRADE TO PRO Go ad-free and unlock premium themes, custom bubble styles and unlimited colour and font customisation — available as an auto-renewing subscription. ━━━━━━━━━━━━━━━━━━━━━━━━━━ ℹ️ GOOD TO KNOW • Hiding the app icon: on Android 9 and below you can hide the icon completely and open the app through a secret browser link. On Android 10 and above, Android requires the icon to stay visible — it simply appears as a normal calculator. • Hiding normal SMS requires the free AdvanceSMS app set as your default SMS app. App-to-app messaging and calls work without it. ━━━━━━━━━━━━━━━━━━━━━━━━━━ 📲 Download Calculator Pro+ — the messaging app that doesn't look like one.
