# ひとつずつ。 vs Study Log

The clearest difference is in-app purchases: ひとつずつ。 at none against Study Log's 1. ひとつずつ。 also leads on ads (none vs shown). On price, device support and iOS requirement there is nothing between them.

Both are free to download. Study Log sells 1 one-off in-app purchase. ひとつずつ。 asks for nothing beyond the download.
