Holy Grail Tracker

Moved over Excel! I am done with making myself crazy with the formula bar!! Zolia gives me all the fields that I need and the ability to create additional ones, is extremely easy to fill out—just tap an icon— haven’t used the reports yet, but I’m looking forward to it. Well done!

Thank you for the review! Really glad to hear that it has been easy to use. - Christine

Privacy forward and flexible

(ETA: hadn’t opened it for awhile and there’s some really nice new functionality, especially improvements in how editing and the UI work. It’s still very flexible and this is impressive design making the flexibility more cognitively accessible.)

Early days for this app, and a promising and usable start. No account needed, data stored on device, straightforward analytics (no LLM). The flip side of flexible and open ended is, of course, that you have to figure out what to do. There are enough starting points to be getting on with as I figure out how to make it really work for my specific situation. I’m really looking forward to seeing how this develops in the future since I really like what I’ve seen so far.

I do wish you weren’t planning subscription only. I know that everyone’s doing it these days but I strongly prefer being able to just buy software.

Thank you for the review, glad it is working well for you at this point & thanks for sticking with it through the setup. Re the subscription -- I entirely understand where you are coming from. I really wish it were feasible to have the app remain entirely free or be a one time purchase. It's possible that things will change, but currently it doesn't look like that will be sustainable in the long run with continued development. We are planning on keeping a generous free tier and keep pricing as affordable as possible. Best, Christine

Tracker I’ve been looking for

I love this app. As someone with severe ME (aka CFS), it’s been difficult to find trackers that fit my symptoms well and require low effort. This is nearly perfect. Very customizable too! If someone wanted to put in the work, it could literally track basically anything.

Minor issues I’ve run into:

- Took me a bit to figure out the editing system. Once I did, it’s been easy.
- Have struggled to co figure the daily notification time and it’s also stopped notifying me.
- Icon looks like trash with the homesceen set to make all icons monochrome.
- Needs iCloud support.
- Would loooove Shortcuts integration so I could record some things just with Siri or something easy.
- Customizing interface feels cramped on my iPhone 12 mini

Thank you so much for the review! I'm glad it's working out well for the most part. Lower effort tracking has been a big priority. Re issues: - Notifications: There's been a bug on iOS where reminders stop for a big chunk of users. It's fixed in the next update. If setting the time is still confusing after that, please let me know what happens. - iCloud: Working on it now hope to get it out soon. - Icon, Shortcuts and the cramped customize screen: thank you, I've added all three to my list. I hadn't heard about the monochrome icon before, so that's really helpful. - Working on making editing clearer and more intuitive, but it's been a bit of a long road. If you have any other thoughts feedback is always really helpful - hello@zolia.app. -Christine

Flexible tracking

Love how flexible the options are, I can build my own tracker that fits my needs instead of being forced into a template, and I don’t have to compromise on privacy! Highly recommend for anyone who manages ongoing symptoms and values their privacy.
