Throwback is your new weekly dose of nostalgia. Are you tired of the same old Instagram feed filled with influencers and their #sponsored posts? Well, Throwback is here to take you back to a simpler time when the only thing you had to worry about was what to wear to your friend's Sweet 16. But here's the catch: Throwback is only open for business on Thursdays. Not kidding. If you're looking for more daily doom scrolling, look elsewhere. Don't worry, the rest of the week you can still add friends, and even send your friends uplifting 'Boosts' (anonymous push notifications to brighten their day!). Each Thursday, we give you a new prompt to take you down memory lane and post pictures of your childhood, those awkward teenage years, or that one time you wore overalls unironically. With Throwback, you'll finally have an excuse to dig through your old photo albums and relive the good old days. So, mark your calendars and get ready to throw it back with us every Thursday. (But don't blame us if your mom starts calling you more often because you're posting pictures of her haircuts from the 90s.) ---------- App made by humans who are always looking for feedback (follow us on Twitter @loopsocialinc), description made by AI which doesn't much care, don't @ us if it's cheesy.

Verdict
The clearest difference is in-app purchases: Throwback by Loop at none against Zync's 2. Throwback by Loop also leads on ads (none vs shown) and update cadence (weekly vs every 3 weeks). Zync's advantage is device support (3 vs 1). On price and iOS requirement there is nothing between them.
