### 3/5 — More complicated to import

*2025-05-24*

My favorite feature of ReadMe is the seamlessness of epub import. I just paid $25 for this and the import is completely different, so now I’m stabbing in the dark trying to get the library I already have on the free ReadMe app. What is not making sense is this here maybe yes..?

### 1/5 — Stopped working

*2024-09-22*

Forgets library, constantly reverts to default settings. Needs an update?

### 3/5 — Decent app with some flaws

*2024-06-15*

Overall this works well, I like that it’s fast. The interface is quite clean. 

Like the previous review I used ReadMe and miss the ability to chose where on the page to start speed reading. 

My biggest issue is that the app randomly deletes all the books imported to it. I am not sure if this is a storage issue with iOS but it’s quite annoying to re-add the book I’m reading and find my place in it and my reading speed.

### 1/5 — Horrible update to readme

*2024-05-14*

Where is the customization? I want a black bar with greyed out type for dark mode. I don’t need to know how many words a minute I’m reading. I know. The page progress bar is distracting and the app goes to sleep. Fix please.

### 1/5 — Garbage compared to the old app

*2024-04-01*

This app is useless. Imported 6 books and can’t import any more, but also can’t empty the trash to reduce the number of books to see if that makes a difference.

### 4/5 — For the future.

*2024-03-28*

The application performs the task. 
But:
1) Add pointer for start reeding
2) Add synchronization between devices
3) Improve the time left

### 5/5 — Love Spritz!

*2024-03-19*

The app is obviously still in development but the only feature I’m really waiting for is dark mode since I primarily read at night. 

Using spritz I’ve been able to read a lot more so I'm very grateful! Hope the development continues!

### 3/5 — Old Spritz app worked better

*2024-03-09*

Not sure why the old Spritz was turned off but I figured the alternative was going to be better but it’s just barely good enough for me to continue using.  
The issues I’m having derive from having my stored books STAY within the app for me to use.  I’ve returned to the app many times now to find absolutely nothing saved.  All my stored books have disappeared and need to,  not only be re-loaded to the app but, have their bookmarks redone.  As of today, I’m only loading and reading one book to this app and hoping tomorrow it’s still there.  Sad

### 2/5 — Good start but more to do

*2024-02-23*

I really liked the previous ReadMe! app and I’m glad that ReadOwl is continuing to integrate the spritz reader with epubs. That said I think there are still some usability issues to iron out, including;

When you select text the options for what to do with that text sometimes float on top of the selected text. When that happens it stops you being able to select one of the options.

When using the spritz reader the screen will dim as if you are not using the iPad. If you’re not careful about the pressure you apply to keep the screen on it can lead you to exit the spritz reader.

The spritz reader begins at the start of each page. I preferred how ReadMe! allowed you to choose where on the page to begin using the reader.

The spritz reader in ReadMe! came with more steps to allow you to increase the reading speed gradually. I find the steps in ReadOwl are too big and it hinders progressing to higher reading speeds more gradually.

After you have imported a book you can’t yet organise your epubs into folders.

### 3/5 — Decent has a good ways to go

*2024-01-05*

If this is intended as a replacement for their original app then it has a ways to go. Lacks the ability to jump back a sentence or two while still running the speed reader. Lacks the ability to select start location, no dark mode, speed only available in increments of 50 etc etc. bought it to read my Christmas books this year, but ended up going back to my old favorite app Litz, since defunct & no longer sold, but probably still the best speed reader I’ve come across. Hopefully they plan to improve it & not just offer as a lite version to their original one.
