Ratings and reviews

I had tried another app, but this is by far the best one I've used. I love how much info you can add about each spider and that you can track other animals too. I love the layout so easy to use. love the day/night option. It would be nice to be able to upload a picture of each of my spiders but that's not available. there's been no issues or glitches. it would be nice if it could do vendors for UK and USA. keep up great work! 😁

Good organizer so far, however I do not get any notifications on my phone for reminders to do stuff, which is really frustrating. Edit: I see the response, that makes sense! Thank you for the clarification.

please god use this instead of arachnafiles. no paywall and the ui is significantly better and isnt constantly cramming affiliate links and ads down your throat. also you can store more than 5 pers without paying. i could cry, i spent 40 minutes making a google sheet and then found this app.A+

What’s new

Added a Pre-Molt toggle for spiders, mantises, and other inverts. Turn it on when your animal stops eating before a molt, and feeding reminders pause until you log the molt. Also fixed feeding-due calculations so a long pre-molt fast doesn't look overdue right after a molt is logged.
