Weight Tracker is a weight loss diary and BMI calculator combined — tap in today's number and the charts, body-fat estimates and goal card do the rest. Trusted by over 100,000 installs on Google Play.
QR Code Pro is a QR scanner and generator that opens straight to the camera, decodes on-device, and remembers everything you scanned or created — even in airplane mode.
WiFi Manager works as a WiFi analyzer and who-is-on-my-WiFi checker: list every device on your network, find the least crowded channel, and ping-test your router — all without sending your network map anywhere.
Food Diary & Water keeps meal logging and hydration habits easy: favorites for two-tap entries, gentle water reminders, and a weekly view with zero calorie shaming.
Free to use, offline-first, private by design, and made by someone who answers support email personally. If a dottools app misbehaves, writing to [email protected] reaches the developer — usually the fix ships in the next update.
