Smart Fonts has everything you need to customize your social media captions, bios, Instagram highlights, stories, and more. Stand out from the crowd on the busy, overcrowded social media apps with Smart Fonts. ———————————————————— Here’s what you can do with the Smart Fonts app: ● Smart Fonts allows you to use hundreds of custom fonts all from your iPhone ● Custom Fonts makes easy for you to stand out in a comment section on Instagram, YouTube, TikTok, et cetera (which helps you to achieve one of top comments) ● You can use your custom fonts keyboard across any other app on your iPhone (every social media platform, email apps, in stories, and more) ● Customize your names on social media using fonts and symbols ———————————————————— ◆ Here’s what makes Smart Fonts different from our competitors ◆ The top custom keyboard apps all required you to give them full access to your keyboard (meaning, they could potentially be data mining every single key you press across all of yours app until you remember to disavow them access). We don’t want full access to your keyboard… we don’t want any sort of access to your personal data. Simply download Smart Fonts, enable the custom keyboard in your settings, and that’s it. You can now access all of the customizable fonts that the other big guys offer, and we’re not harvesting every single key that you press on your keyboard. If you’re using a keyboard app that is demanding that you give them FULL ACCESS to your keyboard, delete it immediately (especially if you do banking or sensitive things like input passwords on your iPhone). ———————————————————— If you want to help us fight against the big apps who shamelessly sell off their users’ data, please consider leaving Smart Fonts a review. Every single review helps and really makes a big impact on helping my app grow and reach more people in the App Store. ———————————————————— Smart Fonts Premium policy: Once you sign up to Smart Fonts Premium, you will have full access to all of Smart Fonts's features. You can cancel your subscription any time and you will be sent a reminder before your Smart Fonts subscription begins after your trial. With Smart Fonts Premium, you get access to the full app: ● Full access to 40+ beautiful fonts and 20+ custom keyboards ● Use your custom fonts and keyboards from any app ● No ads ● Cancel anytime Smart Fonts Premium options: ● Smart Fonts Weekly: 3 days free and then $4.99/week ● Smart Fonts Yearly: 3 days free and then $39.99/year Terms of Service: https://andrewlee.ventures/terms-of-use Privacy Policy: https://andrewlee.ventures/privacy ———————————————————— Connect with us on Instagram and Twitter: @SmartFontsApp Have any questions or recommendations?
