  1. 5/5Terrible update doesn’t let you change the time anymore.

    I use this app to put my medicine in. When I forget to put in I could always go back and put my finger on the line of the medicine i took time after I’ve selected the medicine that I have already put in I could put my finger on the time and it would let me change the time to the correct time. Now I do that it’s blank I cannot change the time so I cannot keep an accurate account the medicines I have taken this was a great app five stars I would’ve even given it a 10 now it’s no longer an app that I can use for my medication. It was the best one I have ever found. This just happened after the new update. I have an 8 plus phone. I have had this app for years. I could bring it up at the Doctors office and show them all the medicine I had taken, even print it out. I now will have to find a new one Sooo disappointed. I hope this is an error in your update and it will be corrected. I should never have updated this. I find most updates only make the apples worst. You don’t seem to follow through to check that everything is done correctly and made better before you update. Sooooooo upset and disappointed.

  2. 3/5Fine, but turns into a worse version of itself if you use it for free for long enough

    Tl;dr: I think this app is rigged to make the ads more annoying after you use it for half a year. I downloaded this app because it was the only one I could find that arranges your entries oldest to newest instead of vice versa like a social media feed. And its minimalistic approach is its greatest strength and weakness. (Sometimes I want to attach photos to an entry.) But one day, the app just switched up on me. Every time I opened it, the ad banner at the top of the screen would load for three seconds and then expand to take up 50% of the screen, so I can’t see what I’m typing until I click the little ‘shrink ad’ button in the corner. This change may have simply been added in an update… But it feels more like the app was programmed to wait until I was a long-time, stalwart user, before hitting me with bigger and better-paying ads, believing I’d be so hooked I would either put up with them, or shell out $5 to remove them. My greatest regret is not making a note of the exact day this happened, so now I have to guess based off of the slow decline of my journal-per-month rate: I downloaded this app in February, and my output peters off at July to September? Anyways, future users beware.

  3. 5/5Quick way to jot down important events… and find them again!

    I am really pleased with the ability to journal, backtrack to enter information for past dates, and physically flip through the pages to retrieve information. I do worry about the developer keeping the app current whenever there are iOS updates, because too many times I have embraced an app and put all of my information into it only to have it no longer work and losing everything! Otherwise it’s a solid app. A couple of suggestions for future updates: the ability to add photos or attachments to notebook entries would be awesome. I would also love the ability to maintain more than one “notebook” for different subjects to make it that much easier to refer back to relevant entries.

  4. 4/5Exceptional! Easy to use!

    I have always kept a manual notebook diary. Recently, I considered transferring my journal to app-based. Before purchasing, I decided to try out available apps. This was my first choice. All went well for the first two days. (deleted the rest of my previous review). With some reservations, I finally bought the app. After several journal entries, I felt a growing sense of doom. How do I get my journals into a different medium, like pdf, intact? How do I preserve my recorded thoughts from vanishing some day? What happens if I were to switch phone carriers? Can I sync my entries to a cloudbased repository to be retrieved at will? The questions are endless, and I hope Koji Ito, the developer will read these reviews, and take our interests and concerns into account. I hope he can read and understand English. Domo Arigato. After using the app for some time, I felt a bit more comfortable with it, hence my reevaluation to 4 stars. The minimalist approach is impressive, but an upgrade that includes a search function would help navigate and locate critical records quickly.

  5. 3/5OK

    I like the simple design, minimal bells and whistles are AOK for me. But the app has several issues. There doesn’t seem to be a way to change or enlarge the font. The page flipping doesn’t work consistently, sometimes it is really hard to get the pages to turn. Also when you want to search for something, you get the results but if you open one up and try to go back to the results, it seems to ‘forget’ the search and you have to start over. Worst of all is the unbelievable number of ads. An amazing variety of advertisers, so good for the developer. But they take up about a third of the page and I’d say at least 30% of the time when I click the down arrow to minimize the ad, if my finger is an iota off, it opens the ad instead. Hope these issues can be addressed in an update. UPDATE: arghh! You just moved ads to top where they take up less room but now they cannot be removed?! Please let us get rid of them entirely after we have seen them as was the case before! Or let us revert to the older version!
