# InstaSlide vs PSTR

The clearest difference is rating: PSTR at 4.6 against InstaSlide's 1.0. PSTR also leads on review sentiment (40% vs 0%) and ratings volume (298 vs 1). InstaSlide's advantage is ads (none vs shown). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. InstaSlide sells 2 in-app purchases, starting at $4.99 per 7 days and PSTR sells 8 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.

PSTR holds the better App Store score, 4.6 against 1.0. That said, the two scores are not equally well evidenced: PSTR has 298 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 0% of InstaSlide's written reviews are positive against 40% of PSTR's.

InstaSlide ships an update every 3 weeks, PSTR every 8 days. The most recent releases landed on October 14, 2026 and October 21, 2026 respectively.
