Reliable spelling practice even when wifi drops out. The best offline-capable apps for travel, school connectivity issues, and rural areas.
SpellingJoy Team
Not every learning moment happens within reach of a wifi signal. Whether your school's internet cuts out mid-lesson, your family is on a road trip, or you live in an area where connectivity is unreliable, you need spelling apps that keep working when the wifi does not.
We tested each app in airplane mode to verify what actually works offline versus what just claims to. Some native apps run entirely without a connection, while others let you download content ahead of time. We also included top online-only options for when you do have internet, because the best strategy is usually to have both.
A note on honesty: SpellingJoy is our own product, and it requires internet. We ranked it at #2 because it is the best free option when you have wifi, but if you need true offline capability, native apps like Simplex Spelling are the better choice.
