# SIP vs Water Reminder

The clearest difference is in-app purchases: Water Reminder at none against SIP's 1. SIP's advantage is ads (none vs shown). On price, device support and iOS requirement there is nothing between them.

Both are free to download. SIP sells 1 one-off in-app purchase. Water Reminder asks for nothing beyond the download.
