Comments on TXT Tab Editor: Large TXT File for Android
★★★★★Geoff Phillips· Jul 20, 2026
Unbelievably great app - the best text app I have tested (and I've tested dozens). Developer is considerate, thoughtful, helpful and responsive. I cannot thank you enough. Keep up the brilliant work! I will be recommending this app as a first choice "ago to" text app.
★★★★★David Mingus· Jul 12, 2026
FINALLY! An app to read my plain text file that has a 1. Small download size 2. Attractive, intuitive interface and 3. ALLOWS LINE NAVIGATION (YOU CAN IMMEDIATELY JUMP TO ANY NUMBERED LINE). I have found many apps with the first 2 but not the 3rd and this is what I was desperately looking for personally. I use the app for my daily Bible reading, a large file that I wanted to jump around which was extremely difficult without line navigation. Love it! Could not be more happy! NO ADS!!
