Used to be better

Recent changes have really bogged down the performance of this app. Now you can choose to also track water consumption, but that also slows down the app quite a bit and makes graphs too small to be useful. But at least you can turn that option off.

Most recent change added a bar chart of past daily total caffeine, which again is nice but now you have to wait a long time for the graphics to update before the app is even responsive! And there is no way to turn off the additional chart. And it too makes the daily caffeine level graph too small to be useful.

Please add the ability to turn off the bar chart, and make the graphics space taller so graphs can actually be read. (It’s fine if you have to scroll slightly to see everything).

For an ad-free app it’s still pretty good.

The best caffeine app!

I’ve used this for years to slowly stop my coffee habit without the crushing headaches. It’s so easy to use and has all the measures I need. I just reduce my sleep ready level slightly every few days and monitor the timing of my daytime coffee. Works a treat

Excellent

This app really helps me make sure I can fall asleep easily at bedtime. I like the ability to customize the target amount of caffeine per day, at bedtime, and adjust bedtime. I find it to be an accurate predictor of how long it will take me to fall asleep.
There is one minor bug in the latest version: when logging a new amount the “sleep ready” time shows the current time. It used to correctly show the time I’d be ready for sleep if I took that amount of caffeine, which was helpful in deciding what to consume.
And there are some quirks, like when you add a new custom amount you can’t rename it until after adding it. And newly added custom amounts appear at the very bottom of the list instead of the top. But for an ad-free app it’s great!

Useless App

Maybe there is something I missed with this app, but bought it a couple days ago and, unless there are directions I am aware of, this app was a complete waste of money. I wish I could return it for a refund!

Great app! Couple minor suggestions

Love this app! Would definitely recommend it if you are at all interested in your daily caffeine consumption/looking at improving your sleep!

For the developer, I have a couple suggestions.

1.) I do shift work, so my bed time is in the morning. Up until midnight, the app will say I’ve consumed too much caffeine because it cannot process the time differential for the next day.

2.) The history on the app could be better to show now much total caffeine you have consumed each day.

The app is great overall still. Very helpful to see real time estimated caffeine levels!
