With Synctrain you can securely synchronize files with other devices that have Syncthing installed. You can choose to synchronize full folders, or choose specific files. With Synctrain you can also stream audio and video files from other devices. When you synchronize files, all changes, including deleting files, also happen on your other devices. Do not use Synctrain for back-up purposes, and always keep a back-up of your data. You decide with which devices you share which files. This also means the app makers cannot help you access or recover any lost files. This app is powered by Syncthing. This app is however not associated with or endorsed by Syncthing nor its developers. Please do not expect support from the Syncthing developers. Instead, contact the maker of this app if you have questions.

Say what's on your mind. Derly writes it down. Tap the mascot and talk. When you stop, you get a clear note: a title, the gist in your own words, the points behind it, and any to-dos, with dates when you said them. Everything happens on your iPhone, iPad or Mac. Your voice is never sent to us or anyone else. CHANGE IT BY SAYING SO Open a note and say "drop the part about pricing and add that I'll try it Friday." You see each change before and after, and apply them one at a time or all at once. Every recording is kept. YOURS, AS FILES Every thought is a folder in the Files app: the note as Markdown, the recording, and every edit you spoke. Open them in any app. Nothing is locked in. ALWAYS AT HAND Record from the Action button, Control Center, the Lock Screen, a widget or Siri. A Live Activity shows the time, with pause and stop. SIRI, SHORTCUTS AND SPOTLIGHT Ask Siri to make a note, add to one or read one back. Find any word you said in Spotlight. Build your own flows in Shortcuts, like turning voice memos into notes. TO-DOS WHERE YOU NEED THEM Send to-dos to Reminders with a tap, or have them go there on their own. MAKE IT YOURS Pick the app's color and your mascot's shape and glass, and put them on the app icon too. Tell it your languages, how notes should read, and the names and words it should know. MORE THAN ONE LANGUAGE Talk in the languages you use, even in the same thought. PLANS Free: record as much as you like. Everyday transcripts, notes, to-dos and editing by voice. Plus: Precise transcripts, the most accurate, even with names, jargon and more than one language. Fast transcripts: an hour's meeting in a minute or two. Every color, shape and glass. Your notes on your iPhone, iPad and Mac, through iCloud. Monthly or yearly, with a free week to try it. Prices are shown in the app. Notes are written with Apple Intelligence on devices that support it. On other devices you still get the recording and the transcript. Plus renews automatically unless canceled at least 24 hours before the end of the period. Manage or cancel it in your Apple Account settings.

Verdict
The clearest difference is in-app purchases: Synctrain at none against Derly's 2. Synctrain also leads on iOS requirement (17.0 vs 26.0). Derly's advantage is update cadence (daily vs every 6 weeks). On price, ads and device support there is nothing between them.
