thumbzonekeyboard vs Tensora

This keyboard is designed for real mobile users who type with one thumb. It supports standard mode, left-handed mode, and mirror mode so you can choose the layout that feels most comfortable for your hand. The smart thumb layout reduces finger movement and helps you type faster with less effort. * Vowels and consonants are placed in separate zones, and consonants are grouped by similar pronunciation to make keys easier to find with one thumb. There is no learning curve. You can start typing naturally from the first use. It also includes a built-in calculator. You can quickly calculate numbers without leaving the keyboard, making it useful for shopping, work, and daily tasks. Use it for just 5 minutes a day for one week, and you will not be able to go back to the old QWERTY keyboard. Switch modes anytime depending on how you hold your phone. Whether you are right-handed or left-handed, this keyboard adapts to you. Designed for speed, comfort, and real-world use on smartphones.

Tensora works out guitar and bass string tension on your device, for each string, each set and each tuning. Version 3.0 adds unit weights from any string maker's chart, a backup file for everything you save, and Shortcuts actions. NEW IN 3.0 • Your chart, any brand: on any string, enter the unit weight printed in your string maker's tension chart (lb/in or g/m). Tensora uses it for that string and labels it "Your chart". • Backup & restore: save setups, setlists and settings to one file. Restoring adds to what is on the device. It never deletes or overwrites anything. • Shortcuts actions: "Calculate String Tension" takes a gauge, string type, note and scale. "Current Setup Tension" reports on the setup open in the calculator. • Accuracy review: the bundled plain steel, nickel wound, phosphor bronze and bass nickel values reproduce three published manufacturer set charts within 0.5%. Stainless wound is labeled as a modeled estimate, and interpolated gauges are marked. • Higher-contrast text, VoiceOver labels on icon buttons, and Setlist Lab values in your chosen unit. • The old approximate "Whole set" study is removed. Finder's Balance set uses the real catalog for your instrument. WHAT'S INSIDE • Calculator for 6-, 7- and 8-string electric, 6-string acoustic, and 4-, 5- and 6-string bass. Includes multiscale (fanned-fret) scale per string, a 430–446 Hz reference pitch, and results in lb, kg or N. • Finder: find the closest gauge for a target tension, or a balanced set for your instrument. • Setlist Lab: compare up to eight tuning stages on one captured setup and export a string-by-string CSV. • Tuning library, tuning range sweep, two-setup comparison, guides, unit-weight tables and note frequencies. WHAT TO KNOW Tensions are reference estimates from published unit weights. Real strings vary by brand and construction. The comfort colors are the app's own convention, not safety limits. Tensora is not affiliated with any string maker. iPhone and iPad. One purchase. No account, subscription, ads or tracking.
