TL;DR - the app is incredible. Completely free, no microtransactions or pitfalls, and is super user friendly!I first heard of this app’s concept through a TikTok ad for a competing app, and thought it was great! But the other app required you to PAY to go through your own photos. You could only go through one month at a time, and had to wait 8 hours between them, or you could pay a monthly fee to go through them all.Once I had enough, I decided to delete it and look for an alternative. That’s when I stumbled across this app! Slider took all the great parts of its competitors, and removed all the bad ones. The first thing I noticed: there are NO microtransactions. There’s not even an OPTION to pay for anything! You can go though all your photos, one by one, all in one sitting. Whether you have 8 pictures or 8,000 pictures, you can review them all! In addition, if you accidentally choose to delete a photo, you can undo your choice for completely free, as many times as you want. The app keeps track of which photos you’ve already reviewed, so next time you open it, you can pick up where you left off! And once you’ve reviewed them all, you can start all over again, or even sort the photos by date!Genuinely, I cannot recommend this app enough. The author created it for completely free and doesn’t even offer a way to be compensated. Believe me, if there was a donation page, I would absolutely send some money! Stop paying for apps that scam you, when this one does it bigger and better, for free!
