Frequency Generator (Ape Apps) vs Specgauge

Make sure your device audio is turned on before use (not in vibrate mode)! This frequency generator allows you to generate sine, square, sawtooth, or triangle waves in the 50HZ to 16000 HZ range. The app is easy to use. It can probably be used for multiple purposes, such as dog whistle, noise maker, tinnitus relief, relaxation or meditation, or just annoying your friends. You can set a custom frequency, set a timer, or even tune to a musical note. Let me know what extra features you would like to see added!

Specgauge helps oil suppliers and site operators monitor tank levels in real time, improving efficiency, reliability, and sustainability. Our sensors are installed on oil tanks and securely transmit level data via 4G to a central server. The specgauge app gives you instant visibility of all monitored tanks in one simple dashboard. By knowing exactly when tanks need refilling, you can prevent run-outs at critical sites such as nursing homes, avoid unnecessary deliveries to partially full tanks, and optimize delivery planning. Fewer deliveries mean lower costs, reduced fuel consumption, and a smaller environmental impact—making specgauge better for both your business and the planet.
