I really like this app. I use it to track half a dozen things: meds, exercise, etc. I downloaded it to replace one I had been using for years that was no longer being supported. I sent feedback to the developer to ask for one change: to be able to adjust the period displayed in the graph. And today I looked at the update, and it’s done! Thanks! And for those who complain about the cost: it’s one-time $4, people! A cup of coffee! I am happy to see the developer get some income to encourage continuing support.

Something to consider

Hi, so far I like the app I use it to track my insulin use. I sometimes forget if I took it or not so in the app I mark it so I won’t forget. I would like to see if by any chance it was possible to add a feature where it ask if you would like to repeat the task every day. Example I write insulin on every day of the week and when I take the insulin dose for the morning I mark it off. I have one calendar for AM and one for PM so that is a lot of writing the same thing for every single day of the month. It would be a nice feature to have. Something to consider. Other than that it works great. Thank you!
Developer Response
Thank you for your feedback. We’ve received several requests for a feature to automatically repeat daily tasks. Our team is considering this for future updates, so stay tuned for improvements to make tracking easier.
Exactly what I was looking for
CareyAndrew
A nice calendar on my phone where I can make daily checkmarks to encourage good habits and see the whole month of the glance. I love the OLED black color on this app versus your other app. So much versatility built into it. I love that it’s on the iPad also. I know it backs up automatically, but it would be terrific If there was an automatic sync between the two devices so you wouldn’t have to manually do a restore to get them to be in sync with each other. That’s my biggest suggestion. Thanks for considering it!
Developer Response
Thank you for your feedback. We’re happy to hear our app meets your needs. We’ve received many requests for automatic syncing between devices and are actively looking into adding it. Please look forward to future updates.
PERFECTLY SIMPLE
GabrielGennari
It’s perfect because it’s simple. All the other apps have a bunch of functions and distractions. All I really wanted is a simple thing like this app to simply track my workouts.And this is really perfect.Happy to pay for itIf I could ask for only one small change, is the fact that the counting report consider every mark on the calendar.For example:I went to the gym 5 times this week, so I will put the checkmark 5 times ✅But I will also put 2 times the x ❌For those days that I didn’t work.The problem is that when I see the report, it shows 7 counts. Instead of 5 yes and 2 no’sSo would be fantastic to have a filter according to your emojiThis way I know exactly what is my progress Besides that, everything is perfectThank you to the developer❤️
