What's New in TankLog

1.46

October 28, 2026

NEW: TEXT SIZE Bigger text, icons and buttons, all through the app. Open Settings, find Text Size and pick Large. Every screen was laid out again for it, down to the iPhone SE and in all seven languages, so nothing gets cut off or squeezed. It applies to all your tanks, and Default stays the size you know. MADE FOR iPHONE DUO TankLog now fills the whole inner screen on iPhone Duo. On the closed screen, and on the open screen held sideways, the tabs move into the side column by the camera, down where your thumb is, with the aqua wave on the open tab. Fold or unfold and the layout follows right away. Built for iOS 27. DELETE A TANK FROM SETTINGS You can now delete a tank in Settings under Data, right next to its Export button. Wherever you delete a tank from, TankLog asks a second time and says what will be erased. If you use Cloud Sync, it also tells you the tank goes from all your devices. FIXES & POLISH • Tab labels and icons are a little bigger on iPhone, and when the tabs don't all fit, the bar scrolls sideways instead of shrinking them • Exporting a backup saves just the backup file, without an extra text.txt beside it in Files • Cards, banners and page titles that ran over on smaller iPhones in German, French, Spanish, Italian or Portuguese now fit • More labels in your language: the last reading on test tiles, tank age, and Next due in the Activity Calendar Free. No login required. No subscription.
