Best Cryptogram Apps for 2026
A comparison of the best cryptogram apps for iPhone and Android in 2026. Features, pricing, and which one is worth your time.
The best cryptogram apps share three things. Clean letter swap. Strong hint system. Quick undo. Below are the top picks for iOS and Android in 2026.
DecodeDaily (our pick)
DecodeDaily runs on iOS and Android. Easy, Medium, and Hard levels. Tap a coded letter, type the real letter, and it fills in everywhere. Hint button. Daily puzzle streak tracker. Free to download. No ads if you go Premium ($2.99/month).
Why we like it: clean interface. The letter swap is the smoothest in the space. And the daily streak feature builds the habit we keep talking about.
Cryptogram by Razzle Puzzles
A long-running cryptogram app on both stores. Big library of quotes and quotes-by-author themed packs. The interface is older. Some testers find it slow. Free with ads.
Best if you like themed quote packs and do not care about a streak tracker.
Crossword Cryptic and Cipher Bundle apps
A few general puzzle apps include cryptograms alongside crosswords. Penny Dell Crosswords is the best of these. The cryptogram options inside are small. You finish all the included cryptograms in a week or two.
Better as variety apps than as a main cryptogram home.
What to look for in a cryptogram app
One-tap letter swap is the top must-have. Without it, you tap each cell separately. That kills the flow.
Hint system. A way to reveal one letter when stuck. Saves you from rage-quitting on a tough puzzle.
Auto-save. Close the app and come back later without losing your spot.
Daily puzzle. A new cryptogram each day keeps the habit going.
Ad-free option. Free apps are fine for trial. Paid is worth it for daily use.
Free or paid for cryptogram apps
Try free for two weeks. If the app sticks (you solve at least 5 puzzles), pay for ad-free. Two to three dollars a month is less than one print book and you get unlimited puzzles.
