Top 5 best iOS apps you must try this month
Well, without any further ado, let’s bounce on our listicle for this month.
Lens Distortions
Category: High-quality photo-editing
I get envious when I see someone’s Instagram with photos that seem like they were clicked by a professional. Without any second thoughts, I understand the feeling is mutual for many. Well, you don’t necessarily need a better camera or phone, but it all boils down to how you capture memories and how you process them.
Lens Distortions is a layer-based photo editor that lets you create impressive cinematic content for your social media and beyond. You can add color layers, typography presents, adjustments, deploy erase or mask joins, add photo effects, and more. In fact, the app lets you do just about anything to fine-tune an element or a photo, unlocking possibilities, helping you gain the perfect shot of the day. Imagine your Instagram slays (slang) when you post cinematic content, be it for personal use, for content creation, or business, it will stand out.

SensorScope
Category: Phone Diagnostics
Whether you are buying a new iPhone or iPad or simply upgrading your arsenal with a pre-owned device, this app can be a valuable asset for you. SensorScope pulls out every ounce of information about the sensors on board your iPhone, be it proximity, rotation vector, light sensor, charging status, battery health, camera specs, RAM, NFC, and everything above and beyond.
It is great for those who want to know the specifics of their iPhone and diagnose it properly. This is what helps you find any hardware or capability issues that might be lurking around. I mean, you could find serious issues with a pre-owned iPhone you might be interested in, just in case. If you are buying a new phone (that potentially has a lower chance of pre-fabbed issues), you could be looking at detailed specs that we do not even offer on True-Tech. Call it a superpower and we won’t deny it.

Simple Call Blocker
Category: Call Blocker
I get too many calls from unwanted numbers at times, and it is frustrating if these are more telemarketers wanting to promote their products or services. Your iPhone does have a feature to block spam or unwanted calls, but it has limitations. Simple Call Blocker, as the name suggests, is an app that blocks calls (duh!).
The app supports call blocking for individuals or company numbers. In fact, it has a feature to set a range of numbers to block, where if you find repeated calls from an app/company bearing the same prefix but a different suffix, the app lets you get rid of the entire range of these numbers. For instance, I can block 100 numbers between ‘04 11019 00’ to ‘04 11019 99’, which means even if they change their numbers, the app will detect and block. It just makes your life a bit easier as you no longer have to deal with repeated unknown or spam calls whatsoever.

Cal AI
Category: Calorie Tracker / Lifestyle Enhancer
Watching what you eat is a task. I mean think about it, you have to watch and weigh everything you eat, count its calories, account for how much you need, and other nutritional charts, to know what’s going in your belly.
Cal AI is a great app that makes it a bit easier to track your food. All it takes is the app, the food, and a snap. Once you take a snap, Cal AI will account for nutritional breakdown of the item and give you recommendations, calories you have consumed, and more. It is equipped with various options, tools, and information you’d need to keep a track of your eating habits and take corrective measures for a healthy lifestyle.

RNI Films
Category: Photo-Editing
People usually edit photos on Instagram or other social media to make sure the photos reflect the aesthetic side of the user. With RNI Films, the app lets you edit photos like never before. It has a ton of filters ranging from those of Kodak, Fujifilm, Polaroid, among others. In fact, it has more than 50 different filters just under ‘negatives’, so you can think about other filters.
The app lets you further enhance photos by altering their saturation, brightness, tint, chromatic aberration, adding a date stamp, and a bunch of other tweaks and settings that can be added to grab that perfect shot. Moreover, you can save those settings to apply as a preset to other photos without needing to manually tweak all the levers the next time around. Isn’t it amazing?
