Observant →

Observant uses YouTube reports and the latest data from YouTube Analytics to identify missed opportunities to grow your Content Owner.

Don't waste time hunting through YouTube Studio to find videos or Content ID assets that you forgot to monetize, ads you forgot to enable, publishing claims you forgot to dispute. Observant finds all these and more, and prioritises them for you based on the latest YouTube Analytics data.

Taking advantage of an opportunity is as simple as following links to the precise page in YouTube Studio where you can take immediate action.

And there's no need to worry about stale data. Observant uses the YouTube Reporting API to automatically check for new reports and spot new opportunities every day.

Spell Tracker for Pathfinder 1e →

Make it easy to track your spellcasting in Pathfinder 1e.

Being a spellcaster can be complicated. Don't make it harder with pen and paper or spreadsheets. Use an app that takes care of everything for you. Enjoy the game instead of doing admin.

Spell Tracker keeps track of everything in one place. It remembers which spells you know. It calculates your spells per day. It updates your remaining spell slots as you prepare and cast spells. It tracks the remaining duration of active spell effects. And it puts the rules at your fingertips.

No hassle. No admin. Just play.
