Frequently Asked Questions
How easy is it to install a Catalyst Waterproof Case on my iPhone?
+ -Super easy! It’s like setting a puzzle piece into place. If you can align your toes into the tip of a shoe, then slide in your foot so the heel fits, you’ve got this. Just follow our step-by-step guide here: Installation Guide. Hint: Rotate the Mute Switch fully clockwise. Then align the bottom edge of the iPhone first, ensuring it fits perfectly on the acoustic membrane, then gently press down to fit it securely into position. Make sure the o-ring is clean & installed correctly and snap the case back into the case front making sure to click all around.
Will the case fit my iPhone?
+ -Absolutely! Our waterproof cases hug your iPhone like a tailor-made suit. Just make sure you’re ordering for the right model—because squeezing an iPhone 14 into a case for an iPhone 13 is like trying to wear shoes two sizes too small. Not sure which model you have? Watch this GIF or check out this guide to find your model — it’s like a cheat code for figuring it out! 🕵️♂️📱
Does it protect against water, drops, and impacts?
+ -You bet it does! This case is like a fortress for your phone—completely sealed to laugh in the face of water, drops, and dust. Go ahead, live dangerously (your phone's got this).
Can I use my waterproof case with a screen protector on my iPhone?
+ -Nope! Our case comes with a built-in screen protector that’s ready to go. Adding another one is like trying to zip up a stuffed suitcase—it’ll make your phone bulge a bit and mess with the fit, functionality, and waterproof seal. Remember, this case is built to handle 10m underwater, so no sneaky extras allowed! Let it do its job and keep your phone snug and dry. 🌊📱
Does the case support the speakers & the microphone of my iPhone?
+ -Of course! Your music will sound so clear, your friends might think you’re hosting a concert underwater. 🎶 And speakerphone? Crisp and loud, like your mom yelling at you from across the house. Just remember to align the bottom edge first so it sits perfectly on the acoustic membrane, then press it down gently—treat it like a diva that insists on perfection, and it’ll perform like a star! 🎤📱
Does the built-in screen protector mess with touch sensitivity?
+ -Nope! Our screen protector is so responsive, you’ll forget it’s even there. Swipe, type, and scroll to your heart’s content—it’s like texting on butter (but without the mess). 🧈📱
Are the buttons easy to use with the case on?
+ -Yep! It takes just a tad more effort to press than a naked iPhone, because your iPhone is essentially wearing a wet suit!
How do you take underwater pictures and videos with your case?
+ -Your iPhone’s touchscreen works using something called capacitive signals—basically, your iPhone’s screen is fancy and uses electrical signals from your skin to work, but guess what? Water is also capacitive, so your screen gets confused underwater as it can't tell any difference between your finger vs. water.
The fix? Open the Camera app before you dive in, then use the volume button to snap pics using the volume button. For videos, hit record before you dive in, unless you’re friends with a dolphin who can press it for you. 🐬📸
And don’t forget to keep your phone secure with the included wrist lanyard—or upgrade to our Floating Lanyard, because nobody wants to go fishing for their phone. 🎣📱🐟
Can I use wireless charging with the case on?
+ -Totally! Wireless charging works like a charm. Just lay your iPhone flat on the charging pad like it’s taking a nap, let it chill, and watch the battery fill up. 📱🔋😴
What can I use to clean and disinfect the waterproof case?
+ -Soap and water work great—think of it as giving your case a relaxing spa day. For serious disinfecting, use EPA-approved cleaners to kick those germs to the curb. Your case will thank you for the glow-up! 🧼💧✨
What does IP68 mean?
+ -It means your Catalyst case is like the superhero of phone protection—tested to survive water, dust, and drops like a champ. The IP68 waterproof rating ensures it can survive submersion in water up to 2m for 30 minutes, making it perfect for splashes, rainstorms, or even pool adventures. And here’s the kicker: we rigorously test each of our waterproof iPhone cases, with some models rated for depths of up to 10m! 💧 Plus, it’s fully dustproof, so dirt and sand don’t stand a chance. Bottom line? IP68 means your case is ready for just about anything life throws at it. 🏖️📱
What does MIL-STD-810G mean?
+ -Cases labeled with "military-grade protection" have passed the MIL-STD-810G test, which basically means they’ve been dropped more times than a bad habit and still kept the phone fully functional. But let’s be real—no case is invincible. Drop your phone from a skyscraper, or land it at just the wrong angle, and even our mighty case might meet its match. So, while your case can handle a lot, try not to test its patience! 🦸♂️📱💥
What are your waterproof cases made of?
+ -Our waterproof cases are like a dream team of materials: tough polycarbonate, flexible TPE (basically a super-smart rubber), and trusty silicone. Together, they shield your phone from water, drops, scratches, and life’s little oopsies—all while keeping it looking stylish. It’s like armor for your phone, but way better looking. 🛡️📱✨
How Can I Prevent My iPhone from Sinking to the Bottom of the Ocean?
+ -Easy—just give your iPhone a floatie! 🛟 The Catalyst Floating Lanyard keeps your phone safely afloat, even in deeper waters. Just attach & clip it to your waterproof Catalyst case, and voilà—your phone is now buoyant and ready for action. Know Your Water: Saltwater = better floating (thank you, science). Freshwater? A little less buoyant, but don’t worry, the lanyard’s got you covered in both. 🌊
Stay Secure: Strap it to your wrist, cinch it tight, and go conquer those waves. If it slips off? No biggie—it’ll float like it’s auditioning for "Finding Nemo." 🐠 Think of it as a life jacket so your phone stays safe 🦺, and you stay stress-free—no more "lost at sea" moments for your tech! 🛟📱
What are the most common everyday uses for a waterproof case?
+ -You’d be surprised! Here are some real-life situations where a waterproof case saves the day:
✅ Rain or Snow – No need to panic if you get caught in bad weather. ✅ Bathroom Accidents – Sink, toilet, or bathtub drops? No problem. ✅ Coffee & Kitchen Spills – Because mornings (and cooking) are messy. ✅ Gym & Outdoor Workouts – Protects against sweat, dirt, and dust. ✅ Beach & Pool Days – Take photos in the water without fear. ✅ Shower Jams – Listen to music in the shower without wrecking your phone.
