After a brief test of several of these, i really liked this app. Had to manually go in and change permissions to allow it to change system settings. However, really like the one time $3.50 purchase option. And it does what i want which is a widget that allows you to switch back and forth between 100% and a font size of your choice. This is helpful for me because I have a harder time at night.

Does what it says very well. Allows you to change system font size beyond what is available through the Settings app. ADVANCED: If you have ADB, you can also use this app to change the system zoom ratio (requires WRITE_SECURE_SETTINGS permission). My new Samsung would only zoom down to 88%. I wanted to set it 75%, and this app did it. This setting is system-level, so it's permanent and survives restart. You don't need to keep the app notification active. ADS: interstitial pop-up ads. Buy it!

Great app for the "old" and "blind"...LOL. I just have one question since some are being answered here. I am on Android 11 (new to me...was on 8 rooted cust rom for the last 3 years on previous phone) and it works great, But when it reboots, the font is still modified, but the font size goes to the very biggest on the scale and I set it for 2 tics below. Was there a way to make it stay that I missed or is that a bug? It's not a big deal to fix, but maybe it can be looked at? Thanks for the Great little handy app!!! Still gonna give it 5 Stars!
