Insta Liker lets you earn coins by liking other people's photos, which you can then use to get more likes for your own photos on Instagram. With this app, you can see all kinds of interesting photos that other users have posted and get additional attention for your own photos at the same time.
To begin using Insta Liker, you have to log in to your Instagram account through the app. Once you're in, you'll immediately be presented with a photo by another user that you can like or skip with the prominent buttons below the image. For each photo you like, you'll earn one coin, which then can be used to get additional likes for your own photos. For instance, gaining an additional 25 likes for your images will cost you 50 coins, while adding 1,000 likes will cost 2,000 coins. You choose the photo and then decide how many likes you want to add. There is no way to get coins other than earning them, and you can efficiently switch from earning coins to getting likes by using the large tabs at the bottom of the screen.
This app runs smoothly, and it's free. It doesn't offer a ton of features, but what it does, it does well. Overall, it's not a bad option if you're looking for a new way for getting likes for your Instagram photos, and you don't mind spending some time doing it.
