■ FlashMob is a smart and easy flashlight application for concerts, clubs, sports games, candlelight-rallies and flash mobs. ■ There are many times when we come together with strangers at a place. These strangers together go wild about the same musician, cheer the same team, dance to the same rhythm, or cry for the same idea. Together, we share the same enthusiasm and thoughts gathered in one place. FlashMob was developed as a tool to actively express such thoughts and enthusiasm. ■ Of course, you can also use it when you listen to music at home and you want to feel like you’re at a club. And you can use it to create a mood light in various colors. Or you can type in “yummy” and hold the phone out next to a delicious food when taking a photo of it. If there’s someone to take that photo, of course. Or when you finally meet an alien, you can type in “not for eating” and ask for a handshake. Hm... Please share your tips for using FlashMob in Review. ■■■ Main functions ■■■ 1. FlashMob detects sound and motion, and it controls background, text colors and the flashlight accordingly. 2. You can enter simple texts in the screen. 3. You can freely transform the text’s size and set its position. If the text is too long, you can apply an animation and make it scroll from the right to the left side. 4. You can change the background and text colors. You can also control their setting so the colors respond to sound and motion. 5. Automatic color change – You can set the app so that it changes color according to changing time. If this function is turned on, the app users will see their screens changing to same colors (choose the rainbow button in color selecting menu.) 6. You can enter a simple message on FlashMob’s candlelight image. (The image is a moving image, not a still one.) 7. FlashMob detects various motions including back/forth and left/right movement, which is the most basic motion for cheering, and you can also use the Smart On-Off function. 8. When you use the Smart On-Off function, the flashlight will automatically turn on when you hold it up and turn off when you hold it down. (You can turn this on in the Option menu.) 9. Battery saving function - You can make power-consuming functions turn off automatically when the battery runs out and reaches below the level you set while using FlashMob. (You can turn this on in the Option menu.) ■■■ Interface ■■■ FlashMob’s interface consists of four modes laid out in the shape of a cross, with the main mode in the center. By simply scrolling up and down or sideways, you can quickly move on to the mode you want. 1. Center : Main (Flashlight, microphone, motion sensor, flicker on/off) 2. Top : Options (Motion-sensor’s option, battery saving function, etc) 3. Bottom : Image mode (You can enter simple text on the candlelight image) 4. Left : Flashlight screen mode (You can use the entire screen as flashlight) 5. Right : Text mode (You can select the background color and enter simple text) ■■■ In App Purchase ■■■ Left : Touch-drawing LED Screen ( temporarily FREE ) Down : Rose+Lights Screen ( temporarily FREE ) Top : Upgrade ( Remove Ads )
EasyUnit
Read full descriptionHide full description
Type one value and every other unit is already on screen. There is no "from" and "to" to pick first: kilograms, pounds, grams and ounces sit there together, and they all update as you type. Tap a different card to type in that unit instead. Touch and hold a card to copy its value. It works offline and there is no account. NEW IN 3.0 — A keypad made for converting: add, subtract, multiply and divide right in the field, so "2 × 1.5" cups turns straight into grams — Negative values with ±, for temperatures below zero — Every category on one screen, in groups, with search by unit name or symbol: type "psi" and you land in Pressure — Pin the categories you use, and recent ones stay one tap away — Choose which units each category shows, and in what order FREE CONVERTERS — Length, mass, temperature, volume, speed, area, data and time — Metric, imperial and SI units — Every card shows how its unit relates to the one you typed, like "1 in = 2.54 cm" — Copy a single value, or the whole line ("12 in = 30.48 cm") to paste into a message — Light and dark themes PRO PACK — Cooking: cups to grams by ingredient. A cup of flour is 120 g, a cup of honey is 340 g — Oven: Celsius, Fahrenheit and gas mark, plus the wording recipes use ("Moderate", "Hot") — Shoes: EU, US men's, US women's, UK and centimeters — Clothing: XXS to XXXL across EU, US and UK — Engineering: pressure, energy, power, force, torque, angle and fuel economy Sizes and oven settings are charts rather than formulas, which is why a calculator cannot work them out for you. PRIVATE BY DEFAULT Every conversion happens on your device, and the values you type never leave it. No account, no ads. EasyUnit Pro Pack is a one-time purchase, not a subscription. It unlocks the cooking, oven, shoes, clothing and engineering converters, plus any category added later. The free converters have no limits and no ads. The price for your region is shown in the app before you buy. Terms of Use (EULA): https://apps.tmkm.dev/easyunit/terms Privacy Policy: https://apps.tmkm.dev/easyunit/privacy Made for anyone shopping across EU and US sizes, cooking from a recipe written in the wrong units, or working in units a calculator has never heard of.
