Tensora: String Tension
iOS app by Shadowfetch · App Store ID 6777744797 · iOS
Tensora is a precise offline string-tension calculator for guitar and bass players.
Build a setup, choose tuning, gauge, construction, scale length, and reference pitch, then see per-string and total tension update instantly. Tensora supports electric 6/7/8-string, acoustic 6-string, bass 4/5/6-string, baritone, drop tunings, open tunings, multiscale and fanned-fret setups, saved instruments, Finder recommendations, comparison, and reference learning tools.
Version 1.5 adds Setup Risk Brief, a luthier-style preflight card that scores the active setup and flags large tension spread, strings outside the expected comfort band, and interpolated gauge estimates. It helps users decide when to adjust gauges before saving or sharing a set.
Core tools:
- Per-string and total tension
- Pounds, kilograms, and newtons
- Inches and millimetres
- Adjustable A4 reference pitch
- Gauge finder for target tension
- Balanced-set builder
- Side-by-side setup comparison
- Tuning range view
- Unit-weight reference tables
- Guides for scale length, construction, multiscale setups, and low tunings
Tension values are reference estimates based on standard string physics and bundled unit-weight data. Real strings vary by brand and instrument. Use results as a guide and do not exceed your instrument's safe limits.
Tensora works offline and does not require an account.
