Synalyze It! Pro for Android

Now runs great on Monterey !

I updated to Android 12.3 and now this crashes when trying to open. I checked the system requirements before and saw it needs Android 10.9 or greater, but now on deeper review, it is known to not work with 12.3... So much for trying to research and plan upgrades. Please get it working again.... It was a great program when I could use it.

Deletiing and reinstalling doesn't help. Until that's fiixed, I must giive one star

some UI features seem hidden or possibly missing for the Length item on the bottom bar of the main window, i see you can enter a new length after already selecting some bytes, and the selected bytes change accordingly. but this length is in hex. can u enter the length of a preselected byte range in decimal to change the byte range? also for the Data panel, can we see multiple data items of the same type (e.g. select 8 bytes of the file, see them as two int32 values)? Updated review: developer responded and gave me some hints, thanks! I see there is a "ctrl click" option in the "grammar" / "create struct" that might be what I need. Will update the review when I get a chance to try it out on real data. The hidden options could use some hints on the grammar editor because they seem difficult to find. Also I saw some popup about the application querying your address book for some email addresses? I don't recall exactly what it said. Seems to be an odd thing for a binary editor. I definitely like the "select / copy bytes" then create new file (in the editor) and paste these bytes to fresh file. This lets you easily work with a block of data without having to remember where the block started. Maybe there is a manually mark bytes w/ color or something, but I havent tried to find that yet. Update 2: Tried to create a grammar with seven 4 byte integers in it and that worked ok, but I was unable to figure how to apply this to an arbitrary byte location in the file. I get this error in the bottom panel: "ERROR Failed to map structures." Do grammars have to start at the beginning of the file? Update 3: the bottom small window that shows position and length of selection sometimes disappears or sometimes is there but no data in it. this seemed to happen after i started editing. also i couldnt find if there is a way to select some bytes and zero fill them. when you start typing data to enter, it clears your current byte range selection.' Update 4: this editor seems to be more designed for the concept of parsing files thru a user defined grammer than manual editing. it is very easy to mess up editing a file and/or lose your place and have to start over. editor defaults to Insert editing mode, not Replace. what mode it is in? you have to always check or you will mess up your file. i have not been able to figure how to properly use the grammar maker yet. it seems confusing to me, but maybe you have to do a lot of reading of the manual? Update 5: I ended up writing some ObjC code to to do what I needed w/ binary file format, the editing portions of this app were too jumpy as a beginner at this app. I kept messing up my file and losing my place. Maybe it takes some skill / usage build-up before you get comfortable w/ this app. It was useful for some viewing purposes.

Many (too many) features to review point for point in this limited space, but in short: Does everything expected from a solid and full-featured binary viewer/editor. One notable, *huge* feature is the ability to apply a “grammar” to a file and have the structures of that file type be displayed. Basically, if you’re viewing a JPEG, for example, you would see the header fields (width, height, bits-per-pixel, etc) decoded, alongside the raw data, usually displayed as hex. Those familiar with Ethereal/Wireshark , Hex Editor Neo (on Windows)… will be instantly familiar with this feature. It works really well - even with huge, multi-megabyte files - and the number of grammars is impressive, at least from my albeit limited use so far; it’s offered to download a grammar for nearly every common binary file format I’ve tried (most recently, MP3, which was a welcome surprise). The importance of this feature cannot be overstated! If you work as a developer in low-level protocols or codecs, this saves not just hours, but DAYS of time! I am subtracting 1-Star for a seemingly-small but very annoying and time-wasting bug (*I realize this may be something that only happens on my/some systems. However I think it’s impacting enough to retract a rating point): When I have a file open from a removable drive (e.g. a USB flash drive), and then I finish with it and fully close it in the app, the app still seems to hold on to the file, such that the OS won’t let me eject the drive. I must close the entire app to eject. This is very annoying if I am working with multiple files which I want to continue with, but must replace the USB drive back into the embedded board which I am debugging. (I am running OS X 10.11.6)
