Lightning fast SSH terminal with remote file access. No other app fuses your SSH servers and iOS devices as well as Secure ShellFish. Tap Get and see for yourself. Terminal supports standard text editing gestures for selection, scrolling and copy/paste as well as custom gestures to send arrow keys and tabulator making shell entry and full screen editing with vim or emacs delightful. Bar above the keyboard makes it easy to type special keys and insert snippets. Select and drag filenames out of the terminal as actual files and drag files from other apps into the terminal to upload. Use built-in tmux support to persist terminal sessions if you lose Internet access, pick existing sessions with thumbnails and Handoff sessions between devices. Server file system is available in the Files app and recently accessed files and directories are cached to make them available when offline.

Verdict
The clearest difference is rating: SSH Client at 4.8 against MarkChart's 4.2. SSH Client also leads on ratings volume (1.5K vs 13) and review sentiment (94% vs 72%). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. SSH Client sells 3 in-app purchases, starting at $2.99 per month and MarkChart sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
SSH Client holds the better App Store score, 4.8 against 4.2. That said, the two scores are not equally well evidenced: SSH Client has 1.5K ratings behind it against 13, so its average is the more settled of the two. Written reviews point the same way: 94% of SSH Client's written reviews are positive against 72% of MarkChart's.
SSH Client ships an update weekly, MarkChart fortnightly. Both last shipped on September 23, 2026.
