# Exoplanet vs CollecTeKs

The clearest difference is device support: Exoplanet at 4 against CollecTeKs's 2. Exoplanet also leads on iOS requirement (13.0 vs 17.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. Exoplanet sells 7 one-off in-app purchases and CollecTeKs sells 2 in-app purchases, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.
