# Speed Trigonometry vs TrigQuest

The clearest difference is in-app purchases: Speed Trigonometry at none against TrigQuest's 1. Speed Trigonometry also leads on ads (none vs shown). On price, device support and iOS requirement there is nothing between them.

Both are free to download. TrigQuest sells 1 one-off in-app purchase. Speed Trigonometry asks for nothing beyond the download.
