WhereTimeGo
Tap once and the clock is running: log first, categorise later — three seconds to learn. Entries you forget to file drop into an uncategorised bucket and stay pinned until you fix them. Daily, weekly and monthly pie charts plus time-of-day breakdowns show where your hours actually go, 25/45/60-minute focus timers feed the stats automatically, and goal milestones, widgets and Apple Watch quick logging round it out — all kept on your device by default.
ArtSprout
End the ever-growing pile of children's drawings: scan with automatic edge detection, deskewing and whitening, and each piece files itself into a monthly timeline that records the age it was made at. A gallery wall, short videos and collage posters bring old work back into view, voice notes transcribe on-device, and A4 PDF portfolios print in a click. Fully offline — nothing is collected.
PassKeeper
Turn your phone into a personal digital vault: passwords, bank cards, IDs, keys and backup codes, private notes, Wi-Fi, servers and membership cards across eight types, all encrypted with fully custom fields. Built-in TOTP codes and a strong-password generator, Face ID and gesture unlock, automatic clipboard clearing, and iCloud sync that only ever holds ciphertext.
