GoToSocial★★★★☆A lightweight Fediverse server, with a clean web interface for viewing public posts. Compatible with Mastodon apps and interacts with other ActivityPub platforms.
Instagram★★☆☆☆Like checking out your friends’ vacation photos, but every other photo is an ad, and half of your friends’ pics are full of product placement.

PixelDroid★★★★★Optimized for photo sharing and viewing, works smoothly and integrates well with the system. FOSS, won’t vacuum up your personal data.
Tusky for Mastodon★★★★★Impressed at how smoothly the app works, especially with multiple accounts.
