# Astro Stacker vs +Frames

The clearest difference is rating: +Frames at 5.0 against Astro Stacker's 1.1. Astro Stacker's advantage is monetization model (free vs freemium) and ratings volume (7 vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Astro Stacker sells 3 in-app purchases, starting at $12.99 per month and +Frames sells 2 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

+Frames holds the better App Store score, 5.0 against 1.1. That said, the two scores are not equally well evidenced: Astro Stacker has 7 ratings behind it against 1, so its average is the more settled of the two.

Astro Stacker ships an update fortnightly, +Frames every 2 weeks. The most recent releases landed on November 9, 2026 and November 5, 2026 respectively.
