### 4/5 — Doing What I Need, & I Sense 2024 Will Bring Updates

*2024-01-08, version 2.10*

This app has been spectacular for a very specific collection of data I’m trying to record. But, it can also we used widely. It’s excellent for time-stamping, logging progress, and it charts things pretty well for the “analytically inclined”.  (If you’re OCD this app is excellent for you, with a couple minor glitches.)

What’s awesome is that I’ve been able to get in contact with the developer, who has actually taken some of my suggestions and bettered the app! 😁 What more can you ask for?!

My 4-star review could easily be a 5. I’m just trying to motivate him for the new year. 😉

### 4/5 — Very handy for most things one might care to measure!

*2023-07-06*

I use this app pretty religiously, and it’s excellent for almost everything I do. I removed one star ⭐️ (and would’ve rated 4.5 stars if possible) simply because—often as I use it—I’ve found some bugs that just may drive someone like myself who’s meticulously tracking everything a little batty. 😅 With that said, I’ve made prior contact with the developer and he was super responsive 👍🏼—emailed me back directly and worked on some of them. Would/Will happily upgrade to 5 ⭐️ if he’s still so receptive to users’ constructive feedback and willing to fix minor glitches, or even add features!

### 1/5 — No instructions

*2023-06-20, version 2.9*

I’ve had this app on my phone for like two weeks and still don’t know how to use it because the developers I guess just assumed everyone would already know? I’ll change the review to five once that’s added

### 1/5 — Requires payment to use privacy options

*2023-04-19, version 2.9*

How is this legal? Also collects user content identified to you which is the biggest red flag for a non social app, you can find all this and more in their privacy policy link

### 5/5 — Great for exercise tracking

*2021-10-08, version 2.1*

Really like this app! Very good for tracking exercise and keeping results organized. I also use it for keeping track of my coffee intake lol

### 5/5 — Daytum is back!

*2021-10-06, version 2.1*

New version of the app is an excellent way to track whatever you want. Enjoying the new attributes feature too. Thanks!

### 5/5 — Finally!

*2021-10-02, version 2*

I am so happy this app has been brought back to life. Responsive, more modern, and a lower priced subscription. I used Daytum first in 2011, then remembered it existed and how much I loved it during Summer 2020. I used it to track some work from home data and was so sad it was still stuck in time. I’ve subscribed and look forward to using it for years to come.

### 1/5 — Great idea but buggy

*2016-11-21, version 1.0.3*

Completely unusable on ios10.  Crashes constantly, and if you do manage to get some data into it it's going to be lost. Don't waste your time until they update and fix this horrible app

### 1/5 — Doesn't Even Work

*2016-05-13, version 1.0.3*

This app has one job: track numbers in categories.  It fails.  When I try to enter information, it crashes.  I thought I'd found something to easily track my reading pages per day, but I can't enter anything in the App.  Don't waste your time until they complete a major overhaul.

### 2/5 — Good idea. Crashes/freezes often. Confusing to use

*2016-04-20, version 1.0.3*

Please fix. I want to use this app and don't know if a better alternative. But this isn't usable as is.
